| recycled Spanish beeswax. RESULTS: Chlorfenvinphos, fluvalinate, amitraz, bromopropylate, acrinathrin, flumethrin, coumaphos, chlorpyrifos, chlordimeform, endosulfan and malathion residues were determined by GC-?ECD/NPD/MS detection. Owing to the extreme instability of amitraz, this analyte was transformed into the stable end-metabolite 2,4-dimethylaniline, later derivatised with heptafluorobutyric anhydride and determined by GC- mu ECD/MS. Recoveries from spiked samples ranged from 86 to 108%, while quantification limits varied from 0.10 to 0.30 mg kg-1 using GC- mu ECD/NPD, and from 12 to 85 mu g kg-1 by GC-MSD. Of a total of 197 samples analysed, only eight samples (4%) were free of residues of chlorfenvinphos (0.019-10.6 mg kg-1), fluvalinate was present in 93.6% of samples analysed (0.027 -88.7 mg kg-1), while coumaphos was confirmed in only five of the 134 samples analysed at concentrations of less than 195 mu g kg-1. The remaining acaricides were identified with different levels of incidence at concentrations from 12 to 231 mu g kg-1. CONCLUSIONS: Residues of acaricides were found in an extensive number of beeswax samples. The contamination with chlorfenvinphos and tau-fluvalinate was very relevant, particularly as chlorfenvinphos is not legally authorised for use in beekeeping. The possible impacts of the main acaricides detected on larval and adult honey bees are discussed.

Development and Validation of a Spectrophotometric Method for Soil Adsorption Study of Malathion on Three Indian Soils. 2010 Nov; 92, (10): 1831-1840. Rec #: 3960 Keywords: FATE Notes: Chemical of Concern: MLN Abstract: Abstract: In view of the widespread use of pesticides in agriculture and its associated toxic effects on environment and human beings, the fate of these chemicals in soil is of major concern. The pesticide adsorption process is one of the major factors affecting its persistence and movement in the soil. With a view of studying the fate of malathion in soil, the adsorption of this insecticide was studied on three Indian soils by using batch equilibrium method. To carry out the adsorption study, a new simple, sensitive, and rapid method was developed, based on microwave-assisted alkaline hydrolysis of insecticide to the dimethyl dithiophosphate and its subsequent reaction with copper(I) perchlorate in acetonitrile. On mixing the reagents, a yellow color developed, which was stable for 120 min and was measured at 419 nm. The adsorption of malathion was studied by using Freundlich's adsorption equation and nf values were observed less than 1 in all the soils. The leaching behavior of the insecticide was studied in terms of ground ubiquity score, which was below 1.8, classifying malathion as non-leacher pesticide, and hence it is not hazardous.

Sharma, Deepti; Shardendu, Shardendu, and Sharma, Deepti. Assessing Farm-Level Agricultural Sustainability Over a 60-Year Period in Rural Eastern India. 2011 Sep; 31, (3): 325-337. Rec #: 6190 Keywords: NO TOXICANT Notes: Chemical of Concern: MLN Abstract: Abstract: Agricultural sustainability is a vital parameter to be ascertained locally and globally if food security is to be achieved and maintained. Agricultural sustainability is the combined product of social, economic and ecological sustainability. It is also a function of temporal and spatial variations, a fact which indicates that area-specific sustainability indices need to be designed. We present here an Agricultural Sustainability Index (ASI) for rural eastern India and use it to calculate the ASI for 150 farms for three decades over a 60-year period, viz., 1950-1960, 1980-1990 and 2000-2010 for a representative Indian village of Gangapur (25 degree 83'N, 85 degree 65'E). The ASI was calculated using 30 variables, 10 each of social, economic and ecological sustainability. An extensive questionnaire-based survey was carried out to collect the relevant data. Our study reveals that over a 60-year period, ASI values do not show a statistically significant change. We conclude that the agricultural practices of the region have maintained sustainability so far although the scope for improvement in several broad areas identified by us is immense. Increased ecological literacy and better implementation of government policies, aiming at health, education and better scientist-farmer interactions, must target improved ASI values in coming decades.

Removal of Malathion Insecticide Fromwater by Employing Acoustical Wave Technology. 2011; 40, (4): 122. Rec #: 3750 Keywords: CHEM METHODS Notes: Chemical of Concern: MLN Abstract: Abstract: Organophosphorus pesticides are one of the most prevalent usages for pest control in the country. Such pesticides enter into water sources by different routes. Since drinking of contaminated water at the higher doses than the standard level, may causes undesirable effects to human health and ecosystem. The object of this research was to investigate the effect of various parameters including time, power and concentration on sonodecomposition of malathion insecticide in the water. The sonochemical degradation of malathion was investigated using acoustic wave technology (AWT). AWT with 130 kHz was used to study the decomposition of insecticide solution. Samples were analyzed using HPLC at different intervals times. Effectiveness of AWT at different times (20, 40, 60, 80, 100, and 120 minutes), concentrations of malathion at 2, 4 and 8 mg/L as well as powers of device (300W, 400W, 500W) are compared. These findings showed that the degradation of the malathion insecticide at lower concentrations was greater in comparison to higher concentrations. Also, there was positive correlation between power increasing and the ability to malathion degradation The sonodegradation of malathion at different concentrations and powers was successfully achieved. It has been shown that acoustical wave technology can be used to reduce the concentration of dissolved insecticide using high frequency.

Rec #: 6070 Keywords: FATE Notes: Chemical of Concern: MLN Abstract: Abstract: In this study, 35 representative farmland soil samples from suburban areas in south Shenyang, the capital city in Liaoning province, China, were collected to evaluate the pollution of 114 pesticides. Surface soil samples were air-dried and sieved. Ultrasonic extraction was used for pesticides preparation prior to analysis with gas chromatography-mass spectrometry. The total concentrations of tested pesticides in the area ranged in 0-51.32 ng/g and the average of concentrations was 6.86 ng/g. Six pesticides, including butachlor(with detect frequency 71.4%), p,p'-DDE (88.6%), p,p'-DDT (77.1%), o,p'-DDD (82.9%), hexachlorobenzene (88.6%) and delta -HCB (77.1%), were detected most frequently. It indicated that DDTs (N.D.-40.25 ng/g) and HCHs (N.D.-42.79 ng/g) were the predominant pesticide pollutants in soil because of their long term persistence. On the contrary, most of organophosphorus pesticides, pyrethroids and carbamates were not detected. Spatial variation of six pesticides with high detection frequency (>70%) in soil was illustrated. Pollution levels, characteristics and the possible sources were also discussed. The data were helpful to figure out the pollution of the pesticides and could be further used to evaluate the health risk associated with food safety.

Rec #: 15870 Keywords: FATE Notes: Chemical of Concern: MLN Abstract: Abstract: We report here the degradation of a pesticide, malathion, by Brevibacillus sp. strain KB2 and Bacillus cereus strain PU, isolated from soil samples collected from malathion contaminated field and an army firing range respectively. Both the strains were cultured in the presence of malathion under aerobic and energy-limiting conditions. Both strains grew well in the medium having malathion concentration up to 0.15%. Reverse phase HPLC-UV analysis indicated that Strain KB2 was able to degrade 72.20% of malaoxon (an analogue of malathion) and 36.22% of malathion, while strain PU degraded 87.40% of malaoxon and 49.31% of malathion, after 7 days of incubation. The metabolites mal-monocarboxylic acid and mal-dicarboxylic acid were identified by Gas chromatography/mass spectrometry. The factors affecting biodegradation efficiency were investigated and effect of malathion concentration on degradation rate was also determined. The strain was analyzed for carboxylesterase activity and maximum activity 210 +/- A 2.5 U ml(-1) and 270 U +/- A 2.7 ml(-1) was observed for strains KB2 and PU, respectively. Cloning and sequencing of putative malathion degrading carboxylesterase gene was done using primers based PCR approach. Number of Volumes: 3 ISI Document Delivery No.: 892MN 584.

Rec #: 15900 Keywords: CHEM METHODS Notes: Chemical of Concern: MLN Abstract: Abstract: Studies were undertaken to analyze the residues of commonly used pesticides viz. chlorpyrifos, endosulfan, dicofol, cypermethrin, fenvalerate, propargite, malathion, phorate, carbendazim, carbosulfan, thiamethoxam, and mancozeb in apple of integrated pest management (IPM) and non-IPM samples collected from the IPM and non-IPM fields of Shimla. We also present a method for the determination of these pesticides in apple samples. Residues of chlorpyrifos, endosulfan, dicofol, cypermethrin, fenvalerate, and propargite were analyzed by gas chromatography, while residues of carbendazim, carbosulfan, and thiamethoxam were analyzed by high-performance liquid chromatography. Residues of mancozeb were determined by a colorimetric method. Recoveries of all of the pesticides ranged from 61.30 to 95.46% at 0.1, 0.2, and 1.0 mu g g(-1) levels of fortification with relative standard deviations ranging between 0.8 and 8.7. Apples from IPM and non-IPM orchards were analyzed for these pesticides using a developed method. Except for carbendazim and chlorpyrifos, the residues of all of the pesticides analyzed were below detectable limits. Although residues of carbendazim and chlorpyrifos were below the prescribed limits of maximum residue levels in both IPM and non-IPM orchards, residues were lower in apples from IPM orchards.

Dna Damage and Cholinesterase Activity in Occupational Workers Exposed to Pesticides. 2011 Mar; 31, (2): 278-285. Rec #: 3570 Keywords: HUMAN HEALTH Notes: Chemical of Concern: MLN Abstract: Abstract: The present study was designed to evaluate genotoxicity, acetyl cholinesterase (AChE) activity, hepatic and renal toxicity in occupational workers exposed to mixture of pesticides (n =70) with same number of healthy subjects as controls. The mean comet tail DNA % (TD %) and tail moment (TM) were used to measure DNA damage, while AChE activity and other biochemical parameters such as markers of nephrotoxicity (urea and creatinine) and hepatotoxicity (AST, ALT and ALP) were measured as biomarkers for toxicity due to exposure of pesticides. The occupational workers were continuously exposed to mixture of pirimiphos methyl, chlorpyrifos, temephos and malathion on a regular interval as per usage and activity. The comet assay using lymphocytes of exposed workers showed significantly higher TD percentage value (60.43% vs. 31.86%, p <0.001) and TM value (14.48 mu m vs. 6.42 mu m, p <0.001) in occupational workers as compared to controls. AChE activity in erythrocytes was found to be decreased (3.45KAU/L vs. 9.55KAU/L in controls, p <0.001) and associated with the duration of exposure to pesticides used by the workers. Enzyme levels for hepatic and renal functions were also found significantly different in occupational workers than healthy controls (p <0.001). These results suggest that the exposure to mixture of pirimiphos methyl, chlorpyrifos, temephos and malathion may induce DNA damage, decrease in AChE activity, hepatotoxicity as well as nephrotoxicity. Periodic biomonitoring of these biomarkers along with imparting education and training to occupational workers for safe application of pesticides is recommended for its potential hazards.

Removal of Malathion From Aqueous Solutions and Waste Water Using Fly Ash. 2010 Apr; 2, (4): 322. Rec #: 4260 Keywords: CHEM METHODS Notes: Chemical of Concern: MLN Abstract: Abstract: Fly ash, obtained from a thermal power plant, Anpara, Sonebhadra, India has been used as an effective adsorbent for the removal of malathion from aqueous solutions. The time required to attain equilibrium was found to increase from 40 to 60 minutes as the initial malathion concentration increases from 1 to 10 mg/L. The optimum pH value for adsorption was 4.50. The removal of malathion increased by increasing the temperature indicating endothermic nature of removal process. The fly ash exhibited first order rate kinetics and followed both Langmuir and Freundlich isotherm models. Endothermic nature of adsorption process was further supported from increasing values of Langmuir and Freundlich constants with increase in temperature. The adsorbent can be used as an economical product for the removal of malathion from wastewater also. A comparison of the adsorption capacity of fly ash with other adsorbents shows that fly ash can be used for the removal of malathion from aqueous solutions.

A novel method for pesticide analysis in refined sugar samples using a gas chromatographyÇômass spectrometer (GCÇôMS/MS) and simple solvent extraction method. 2011 May 1-; 126, (1): 379-386. Rec #: 1580 Keywords: CHEM METHODS Notes: Chemical of Concern: MLN Abstract: A sensitive method for the quantification of 11 pesticides in sugar samples to the ++g kg êÆ1 level has been developed. These pesticides are often used in an agricultural context. A simple solvent extraction followed by selective analysis using a gas chromatographyÇômass spectrometric method was used. This method was accurate (_+99%) as it possesses limits of detection in the 0.1-++g kgêÆ1 range, and the coefficients of variations are less than 15% at the low ++g kgêÆ1 end of the methodÇÖs linear range. The percent recovery of all the pesticides at the lowest levels of detection ranges from 82% to 104%. This method was used for the quantification of pesticides in sugar samples collected from different factory outlets from different parts of India. In this study, 27 refined sugar samples were analysed in which one sample showed a detectable level of the chlorpyrifos pesticide. This study showed that Indian sugar is free from the commonly-used pesticides at the low ++g kgêÆ1 levels.

[Echinocytosis and Changes of Medium Weight Molecules Content in Endo- and Exogenous Intoxications]. Rec #: 9470 Keywords: NON-ENGLISH Notes: Chemical of Concern: MLN Abstract: ABSTRACT: The purpose of this study was to detect the interrelationship between the increased serum concentration of the medium weight molecules (MWM) and echinocytosis, to establish the rate of echinocyte appearance in blood in endogenous and exogenous intoxications and the dependence of echinocytosis on phosphacol and carbophos doses or the degree of endogenous intoxication. Two series of studies were conducted. In the 1st series, the experiments were conducted on outbred albino rats. Rats of the 1st group received phosphacol in doses equal to 0.5, 5.0 and 50 LD50, while the rats of the 2nd group were given carbophos in doses equal to 0.1 and 1.0 LD50. In the 2nd series, the blood of cats with chronic renal failure at uremic stage was studied (as an example of endogenous intoxication). In all the animals, serum MWM concentrations were measured together with the relative echinocyte content and echinocytes were examined with electrone microscope. The ability of MWM to influence erythrocyte deformation was evaluated. Increased MWM concentrations and echinocyte content was found in association with the increase of intoxication severity, while echinocyte percentage in cats' blood was augmented under the action of MWM.

Rhinitis Associated with Pesticide Use Among Private Pesticide Applicators in the Agricultural Health Study. 2010; 73, 1382-1393. Rec #: 15910 Keywords: HUMAN HEALTH Notes: Chemical of Concern: MLN Abstract: Abstract: Farmers commonly experience rhinitis but the risk factors are not well characterized. The aim of this study was to analyze cross-sectional data on rhinitis in the past year and pesticide use from 21,958 Iowa and North Carolina farmers in the Agricultural Health Study, enrolled 1993-1997, to evaluate pesticide predictors of rhinitis. Polytomous and logistic regression models were used to assess association between pesticide use and rhinitis while controlling for demographics and farm-related exposures. Sixty-seven percent of farmers reported current rhinitis and 39% reported 3 or more rhinitis episodes. The herbicides glyphosate [odds ratio (OR) = 1.09, 95% confidence interval (95% CI) = 1.05-1.13] and petroleum oil (OR = 1.12, 95% CI = 1.05-1.19) were associated with current rhinitis and increased rhinitis episodes. Of the insecticides, four organophosphates (chlorpyrifos, diazinon, dichlorvos, and malathion), carbaryl, and use of permethrin on animals were predictors of current rhinitis. Diazinon was significant in the overall polytomous model and was associated with an elevated OR of 13+ rhinitis episodes (13+ episodes OR = 1.23, 95% CI = 1.09-1.38). The fungicide captan was also a significant predictor of rhinitis. Use of petroleum oil, use of malathion, use of permethrin, and use of the herbicide metolachlor were significant in exposure-response polytomous models. Specific pesticides may contribute to rhinitis in farmers; agricultural activities did not explain these findings. Number of Volumes: 20 ISI Document Delivery No.: 647GM 595. Slauter, R.

Effects of Insecticides on Postmortem Interval: Implications for Forensic Investigations. 2011. Rec #: 8030 Keywords: HUMAN HEALTH Notes: Chemical of Concern: MLN Abstract: Abstract: Postmortem interval (PMI) is the length of time that occurs between death of a person and the subsequent discovery of the body. PMI can be determined in a variety of ways depending on how long the body has been exposed to the environment. Forensic entomologists can use the identity and growth stages of insects to determine the PMI. During the initial stages of decomposition, the primary insects to attack the body are blow flies and flesh flies. The abundance and age of the fly larvae are used to calculate the PMI according to established life cycle times for each species. Several factors can alter the apparent PMI via alterations in the insect activity. These factors include temperature, humidity, sunlight, and chemicals present in or on the body. This research focused on the alteration of PMI by insecticides applied to the body after death. Readily available insecticides were chosen from three classes of pesticides: malathion, an organophosphate; carbaryl, a carbamate; and permethrin, a pyrethroid. Pig carcasses were coated with a 0.5% solution of one of the three pesticides and placed in a remote site protected from predation. The pigs were monitored daily for the appearance of fly larvae. Larvae were collected and analyzed by GC/MS for the presence of the insecticides. The insecticides deterred the arrival of flies in the following decreasing potency: permethrin, carbaryl, and malathion.

Low Temperature Followed by Matrix Solid-Phase Dispersion-Sonication Procedure for the Determination of Multiclass Pesticides in Palm Oil Using Lc-Tof-Ms. 2011 Feb 28; 186, (2-3): 1308-1313. Rec #: 3620 Keywords: CHEM METHODS Notes: Chemical of Concern: MLN Abstract: Abstract: A simple and effective multiresidue method based on precipitation at low temperature followed by matrix solid-phase dispersion-sonication was developed and validated to determine dimethoate, malathion, carbaryl, simazine, terbuthylazine, atrazine and diuron in palm oil using liquid chromatography time-of-flight mass spectrometry (LC-TOF-MS). Liquid-liquid extraction (LLE) followed by low temperature method were optimized by studying the effect of type and volume of organic solvent (acetonitrile, acetonitrile:n-hexane (3:2 v/v) and acetone) and time of freezing to obtain high recovery yield and low co-extract fat residue in the final extract. The optimal conditions for matrix solid-phase dispersion (MSPD) were obtained using 5g of palm oil, 2g of primary secondary amine (PSA) as dispersing sorbent, 1g of graphitized carbon black (GCB) as clean-up sorbent and 15mL of acetonitrile as eluting solvent under conditions of 15min ultrasonication at room temperature. Method validation was performed in order to study sensitivity, linearity, precision, and accuracy. Average recoveries at three concentration levels (25, 50 and 100 mu gkg super(-1)) were found in the range of 72.6-91.3% with relative standard deviations between 5.3% and 14.2%. Detection and quantification limits ranged from 1.5 to 5 mu gkg super(-1) and from 2.5 to 9 mu gkg super(-1), respectively.

A Simple and Efficient Multi-Residue Method Based on Quechers for Pesticides Determination in Palm Oil by Liquid Chromatography Time-of-Flight Mass Spectrometry. 2012 Sep; 184, (9): 5821-5828. Rec #: 2530 Keywords: CHEM METHODS Notes: Chemical of Concern: MLN Abstract: Abstract: In this study, a rapid, specific and sensitive multi-residue method based on acetonitrile extraction followed by dispersive solid-phase extraction (d-SPE) clean-up was implemented and validated for multi-class pesticide residues determination in palm oil for the first time. Liquid-liquid extraction followed by low-temperature precipitation procedure was evaluated in order to study the freezing-out clean-up efficiency to obtain high recovery yield and low co-extract fat residue in the final extract. For clean-up step, d-SPE was carried out using a combination of anhydrous magnesium sulphate (MgSO sub(4)), primary secondary amine, octadecyl (C sub(18)) and graphitized carbon black. Recovery study was performed at two concentration levels (10 and 100 ng g super(-1)), yielding recovery rates between 74.52% and 97.1% with relative standard deviation values below 10% (n=6) except diuron. Detection and quantification limits were lower than 5 and 9 ng g super(-1), respectively. In addition, soft matrix effects ( less than or equal to plus or minus 20%) were observed for most of the studied pesticides except malathion that indicated medium (20-50%) matrix effects. The proposed method was successfully applied to the analysis of suspected palm oil samples.

Determination of Organophosphorus Pesticides Using Dispersive Liquid-Liquid Microextraction Combined With Reversed Electrode Polarity Stacking Mode-Micellar Electrokinetic Chromatography. 2012 Aug 30; 98, 62-68. Rec #: 2570 Keywords: CHEM METHODS Notes: Chemical of Concern: MLN Abstract: Abstract: A rapid and sensitive method using two preconcentration techniques, dispersive liquid-liquid microextraction (DLLME) followed by reversed electrode polarity stacking mode (REPSM) was developed for the analysis of five organophosphorus pesticides (OPPs) by micellar electrokinetic chromatography (MEKC). Parameters that affect the efficiency of the extraction in DLLME and preconcentration by REPSM, such as the kind and volume of the extraction and disperser solvents, salt addition, sample matrix and injection time were investigated and optimized. Under the optimum conditions, the enrichment factors were obtained in the range from 477 to 635. The linearity of the method for parathion, azinphos and fenitrithion was in the range of 20-1000 ng mL-1, and for malathion and diazinon in the range of 50-1000 ng mL-1, with correlation coefficients (r2) ranging from 0.9931 to 0.9992. The limits of detecton (LODs) at a signal-to-noice ratio of 3 ranged from 3 to 15 ng mL-1. The relative recoveries of five OPPs from water samples at spiking levels of 20 and 200 ng mL-1 for parathion, azinphos and fenitrithion, and 50 and 500 ng mL-1 for malathion and diazinon, were 69.5-103%. The proposed method provided high enrichment factors, good precision and accuracy with a short analysis time.

Therefore, monitoring of pesticide residues was carried out on stored maize, cowpea and millet from eight localities. The determination of residues of organochlorines (lindane, alpha-endosulfan and beta-endosulfan), organophosphorus compounds (malathion and pirimiphos-methyl), synthetic pyrethroids (permethrin) and carbamates (carbufuran) was performed using GC-ECD/NPD and GC-MS for confirmation. Organochlorine pesticides were detected more frequently and in higher concentrations, ranging from 0.02 +/- 0.01 mgkg(-1) for beta-endosulfan in millet to 9.53 +/- 4.00mg kg(-1) lindane in maize, than organophosphorus compounds, with concentrations varying from 0.04 +/- 0.03mg kg(-1) for pirimiphos methyl to 0.23 +/- 0.38mg kg(-1) for malathion in maize. Permethrin was found only in maize at 0.39 +/- 0.23mg kg(-1). No carbofuran was found. More than 75% of samples contained pesticide residues above the maximum residue limit (MRL); showing a potential human dietary risk related to consumption of these grains.

Fingerprinting Biological Materials Based on Fourier Transform Infrared Spectroscopy. 2009. Rec #: 8170 Keywords: CHEM METHODS Notes: Chemical of Concern: MLN Abstract: Abstract: At the start of the twenty-first century, infrared spectroscopy is one of the standard workhorses of the manufacturing world, whether in semiconductor production, process control in chemical engineering, or environmental monitoring. It is relatively inexpensive, rapid, very sensitive, and can provide quick and efficient information on chemical reaction conditions through its ability to detect characteristic vibrations of molecules of interest in the process under investigation. In the recent years, successful identification and detection of Bio-chemicals have been attracting great interests and have many applications on biomedicine and national defense and security. In practice this goal has been limited by the detection technology. With increasing technology in infrared spectroscopy, especially Fourier Transform Infrared Spectroscopy (FTIR), along with advanced development of sample preparation techniques, computer filtering and manipulation of the results, samples in vapor, liquid and solid forms all can be measured quickly and accurately now. In this thesis, targeted for future sensor design, a Chalcogenide glass based waveguide is designed for bio-sensors in the infrared optical frequency range, and various bio-chemicals have been fingerprinted from Mid-IR to THz by utilizing the tremendous power of FTIR in the spectroscopic characterizations. The studied bio-chemicals were carefully selected based on their potential impacts, such as pharmaceutical and medical related insulin and glucose, national defense and security concerned sucrose, malathion and albumin as simulants for explosives, VX nerve agents and proteinaceous toxin, respectively. As results, the designed waveguide structure has great potential in the application on bio-sensing, and the identified vibrational peaks for these bio-chemicals created a solid foundation for future bio-sensor design and therefore would contribute huge impact on pharmaceutical/medial and national defense and security.

Sozeri, B.; Gulez, N.; Aksu, G.; Kutukculer, N.; Akalin, T., and Kandiloglu, G. Pesticide-Induced Scleroderma and Early Intensive Immunosuppressive Treatment. 2012; 67, 43-47. Rec #: 15970 Keywords: HUMAN HEALTH Notes: Chemical of Concern: MLN Abstract: Abstract: The authors report 2 children with generalized cutaneous sclerosis exposed to pesticides containing malathion and diniconazole. Treatment with immunosuppressives resulted in partial improvement in the cutaneous signs, particularly over the face, trunk, and proximal limbs. The considerable exposure to chemicals related with the initiation of symptoms and absence of organ involvement suggested a diagnosis of chemically induced scleroderma-like disorder. Although autoantibodies were negative, previously reported relevant associations of anti-kinetochore and anti-topoisomerase function of active ingredients-diniconazole and phosphorodithioate-and solvents of these pesticides are also discussed. Careful follow-up for systemic involvement is warranted, since these agents may have triggered systemic scleroderma in these patients. Elimination of chemical exposure of children is stressed.

Monitoring of Pesticide Residues in Market Basket Samples of Vegetable From Lucknow City, India: Quechers Method. 2011 May; 176, (1-4): 465-472. Rec #: 3500 Keywords: CHEM METHODS Notes: Chemical of Concern: MLN Abstract: Abstract: The study was conducted on 20 vegetables including leafy, root, modified stem, and fruity vegetables like bitter gourd, jack fruit, french-bean, onion, colocassia, pointed gourd, capsicum, spinach, potato, fenugreek seeds, carrot, radish, cucumber, beetroot, brinjal, cauliflower, cabbage, tomato, okra, and bottle gourd. Forty-eight pesticides including 13 organochlorines (OCs), 17 organophosphates (OPs), 10 synthetic pyrethriods (SPs), and eight herbicides (H) pesticides were analyzed. A total number of 60 samples, each in triplicates, were analyzed using Quick, Easy, Cheap, Effective, Rugged, and Safe method. The quantification was done by GC-ECD/NPD. The recovery varies from 70.22% to 96.32% with relative standard deviation (RSD) of 15%. However the limit of detection ranged from 0.001--0.009 mg kg-1 for OCs, SPs, OPs, and H, respectively. Twenty-three pesticides were detected from total 48 analyzed pesticides in the samples with the range of 0.005--12.35 mg kg-1. The detected pesticides were: Delta *S-HCH, Dicofol, Delta *S-Endosulfan, Fenpropathrin, Permethrin-II, Delta *b-cyfluthrin-II, Fenvalerate-I, Dichlorvos, Dimethoate, Diazinon, Malathion, Chlorofenvinfos, Anilophos, and Dimethachlor. In some vegetables like radish, cucumber, cauliflower, cabbage, and okra, the detected pesticides ( Delta *S-HCH, Permethrin-II, Dichlorvos, and Chlorofenvinfos) were above maximum residues limit (MRL) (PFA 1954). However, in other vegetables the level of pesticide residues was either below detection limit or MRL.

Staley, Z. R.; Rohr, J. R., and Harwood, V. J. The effect of agrochemicals on indicator bacteria densities in outdoor mesocosms. 2010; 12, 3150-3158. Rec #: 16000 Keywords: BACTERIA Notes: Chemical of Concern: MLN Abstract: Abstract: P>Water bodies, which are monitored for microbial water quality by quantification of faecal indicator organisms (IOs), can contain various zoonotic pathogens contributed by livestock waste and other sources. Sediments can serve as reservoirs of IOs and other enteric microorganisms, including pathogens. Agrochemicals may influence the survival of these microorganisms in water bodies impacted by livestock waste by enhancing or reducing their survival. Complex, 1100 l, freshwater mesocosms containing leaf litter, zooplankton, periphyton, phytoplankton, and invertebrate and vertebrate animals were used to investigate the Directory: pesticides -> nas nas -> Appendix 1-10: Summary of Diazinon Monitoring Data nas -> Description of revision nas -> Appendix 2 Chlorpyrifos Species Sensitivity Distribution Analysis for Fish nas -> Appendix 2 Open Literature Review Summaries for Malathion Download 5.18 Mb.
