| monitored in the tissues of some birds of prey (wild birds), some species of algae, fish and crustaceans. The results obtained revealed: (1) The presence of some Organochlorines (OC) in the tissues of many of the tested birds represented in (DDE, Heptachlore, HCH, Dicofole). (2) The presence of high residues of Organophosphorus (OP) pesticides represented in malathion and diazinon in most of the tested birds. But they were not detected with high levels in any of fish, crustaceans or algae. (3) The presence of high concentrations of (OC) compounds in the tissues of algae, crab, mullet and some birds (moorhen-cormorant and gulls). Meanwhile, none of those compounds was detected in the water samples. (4) The presence of high levels of all detected pesticides in the tissues of crab makes it the very acceptable bioindicator to mirror the pollution of the lake, then followed by algae. (5) Pollutants can be transferred through the food chain which causes biomagnification of them in the bodies of the higher organisms in the food chain. It could be concluded that implementation of the environmental management practices in Lake Temsah is still needed to protect these ecosystems from more pollutions which could affect human health and environment.

Rec #: 13020 Keywords: REVIEW Notes: Chemical of Concern: MLN Abstract: Abstract: The prospect of malaria eradication has been raised recently by the Bill and Melinda Gates Foundation with support from the international community. There are significant lessons to be learned from the major successes and failures of the eradication campaign of the 1960s, but cessation of transmission in the malaria heartlands of Africa will depend on a vaccine and better drugs and insecticides. Insect control is an essential part of reducing transmission. To date, two operational scale interventions, indoor residual spraying and deployment of long-lasting insecticide-treated nets (LLINs), are effective at reducing transmission. Our ability to monitor and evaluate these interventions needs to be improved so that scarce resources can be sensibly deployed, and new interventions that reduce transmission in a cost-effective and efficient manner need to be developed. New interventions could include using transgenic mosquitoes, larviciding in urban areas, or utilizing cost-effective consumer products. Alongside this innovative development agenda, the potential negative impact of insecticide resistance, particularly on LLINs, for which only pyrethroids are available, needs to be monitored.

Pesticide Occurrence and Aquatic Benchmark Exceedances in Urban Surface Waters and Sediments in Three Urban Areas of California, Usa, 2008ă˘[Euro]"2011. 2013 May; 185, (5): 3697-710. Rec #: 5360 Keywords: FATE Notes: Chemical of Concern: MLN Abstract: Abstract: Urban pesticide use has a direct impact on surface water quality. To determine the extent of pesticide contamination, the California Department of Pesticide Regulation initiated a multi-area urban monitoring program in 2008. Water and sediment samples were collected at sites unaffected by agricultural inputs in three areas: Sacramento (SAC), San Francisco Bay (SFB), and Orange County (OC). Samples were analyzed for up to 64 pesticides or degradates. Multiple detections were common; 50Ă‚ % of the water samples contained five or more pesticides. Statewide, the most frequently detected insecticides in water were bifenthrin, imidacloprid, fipronil, fipronil sulfone, fipronil desulfinyl, carbaryl, and malathion. Bifenthrin was the most common contaminant in sediment samples. Key differences by area: OC had more pesticides detected than SAC or SFB with higher concentrations of fipronil, whereas SAC had higher concentrations of bifenthrin. The most frequently detected herbicides were 2,4-D, triclopyr, dicamba, diuron, and pendimethalin. Key differences by area: OC and SFB had higher concentrations of triclopyr, whereas SAC had higher concentrations of 2,4-D and dicamba. Detection frequency, number of pesticides per sample, and pesticide concentration increased during rainstorm events. In water samples, all of the bifenthrin, malathion, fipronil, permethrin, and [lambda]-cyhalothrin detections, and most of the fipronil sulfone and cyfluthrin detections were above their lowest US EPA aquatic benchmark. Diuron was the only herbicide that was detected above its lowest benchmark. Based on the number of pesticides and exceedances of aquatic benchmarks or the high number of sediment toxicity units, pesticides are abundant in California surface waters.[PUBLICATION ABSTRACT] Keywords: Environmental Monitoring Keywords: Pesticides -- analysis Keywords: California Keywords: Geologic Sediments -- chemistry Keywords: Water Pollutants, Chemical -- analysis Keywords: Pesticides Keywords: Water Pollution, Chemical -- statistics & numerical data Keywords: Water Pollutants, Chemical Keywords: Rivers -- chemistry Keywords: Cities -- statistics & numerical data Keywords: Environmental Studies English.

Entry, James a; Sojka, Robert E, and Entry, James A. Matrix-Based Fertilizers Reduce Pesticide Leaching in Soil. 2012 Mar; 223, (3 ): 1295-1302. Rec #: 2790 Keywords: FATE Notes: Chemical of Concern: MLN Abstract: Abstract: The presence of pesticides in groundwater has been documented in several large-scale studies and numerous small-scale investigations. Pesticide leaching through soil has been identified as a major cause for the occurrence of these chemicals in surface and groundwater. We developed matrix-based fertilizers (MBFs) that have been shown to reduce N and P leaching. We tested the efficacy of the ionic bonds in the MBFs to reduce 2,4-dichlorophenoxyacetic acid (2,4-D), metolachlor, thiophanate methyl, carbaryl, diazinon, and malathion leaching in soil columns. After 7 days 2,4-D, thiophanate methyl, carbaryl, and malathion did not leach in sufficient quantities to determine if the MBF fertilizers reduced leaching compared with the control and the slow-release fertilizer Polyon registered . The MBF fertilizers leached from five to 30 times less metolachlor than the control and Polyon registered treatment. Treatments with MBF fertilizers leached from two to 72 times less diazinon than the control treatment. The MBF fertilizer treatment leached from eight to 268 less diazinon than columns receiving Polyon registered . The MBF formulations allow compounds with both anionic and cationic charges to bind with the Al(SO sub(4)) sub(3) 3H sub(2)O and/or Fe sub(2)(SO sub(4)) sub(3) 3H sub(2)O-lignin-cellulose matrix. When pesticides are added to the soil amended with matrix-based fertilizers, the ion exchange matrix will likely bind the metolachlor and diazinon to the Al(SO sub(4)) sub(3) 3H sub(2)O and/or Fe sub(2)(SO sub(4)) sub(3) 3H sub(2)O-starch-cellulose-lignin matrix thereby substantially reducing leaching. The MBFs could be used to limit both nutrients and pesticide leaching from agricultural fields.

Delayed Neuropathy Due to Organophosphate Insecticide Injection in an Attempt to Commit Suicide. 2009 Mar; 4, (1): 84-87. Rec #: 7730 Keywords: HUMAN HEALTH Notes: Chemical of Concern: MLN Abstract: Abstract: Organophosphates (OPs) are commonly used as pesticides throughout the world. Exposures to OPs cause a significant number of poisonings and deaths every year. Organophosphate-induced delayed polyneuropathy is a sensory-motor distal axonopathy which usually occurs after exposure of certain OP insecticides. Neuropathies due to ingestion of OPs have rarely been reported in the literature. Moreover, until now, there is no report of a patient developing organophosphorus injection-induced delayed neuropathy in the literature. We report a patient with serious organophosphorus-induced delayed neuropathy due to malathion injection. The patient was a 32-year-old female who self-injected undetermined amounts of malathion over the median nerve trace on the forearm crease in a suicide attempt which resulted in peripheral neuropathy. eng.

Rec #: 13060 Keywords: HUMAN HEALTH Notes: Chemical of Concern: MLN Abstract: Abstract: Pesticides have been of great benefit to agriculture in the Philippines by decreasing crop losses clue to insects, weeds, plant diseases, rodents, and other pests. However, they may build-up in the food chain and can cause contamination of the environment. We examined farmers' pesticide usage in southern sub-catchments of Laguna de Bay, which is a crucial water resource subject to intensive investigations to identify types and sources of pollution. Before the monitoring of pesticides in surface waters was commenced it was necessary to conduct a survey of the pesticides being used by the growers in the catchment in order to select the pesticides that should be monitored. Our survey found that nearly all growers in Lucban and Laguna, irrespective of crop grown, used the pyrethroid-based insecticides L-cyhalothrin and cypermethrin. In rice, pesticides were applied one to three times per season, while in vegetables, L-cyhalothrin and cypermethrin insecticides were applied five times and the other insecticides were applied two to four times throughout the cropping season. In Laguna other insecticides used were carbofuran, endosulfan and a formulated product of BPMC (fenobucarb) and chlorpyrifos. In Lucban other insecticides used were malathion, profenofos, chlorpyrifos, carharyl, niclosamide and metaldehyde. Butachlor and 2,4-D herbicides were used to control weeds and were applied once throughout the growing. Some fungicides were also applied. An estimation of the potential loads of chemicals moving into waterways has shown that L-cyhalothrin, pretilachlor, niclosamide, butalchlor, carbofuran and profenofos are most likely to be present in waterways in the Lucban and Pagsanjan regions in the largest quantities based on the quantities applied and/or use in a number of crops.

Rec #: 13090 Keywords: CHEM METHODS Notes: Chemical of Concern: MLN Abstract: Abstract: This paper reports the results of a 5-year study to evaluate pesticide levels, derived from orchard activities, on Italy's most common orange cultivar (Citrus sinensis, L. Osbeck, cv. Tarocco). Using a Bayesian approach, the study allowed both the qualitative (number) and quantitative distributions (amount) of pesticides to be determined with its own probability value. Multi-residue analyses of 460 samples highlighted the presence of ethyl and methyl chlorpyrifos, dicofol, etofenprox, fenazaquin, fenitrothion, imazalil, malathion and metalaxil-m. A total of 30.5% of samples contained just one pesticide, 2.16% two pesticides and 0.65% of samples had three pesticides present simultaneously. The most common residue was ethyl chlorpyrifos followed by methyl chlorpyrifos. Estimated daily intake (EDI) values for ethyl and methyl chlorpyrifos, as well as the distance from the safety level (non-observed adverse effect level, NOAEL), were calculated. The risk was differentiated (1) to take account of the period of actual citrus consumption (180 days) and (2) to discriminate the risk derived from eating oranges containing a certain level of chlorpyrifos from unspecified pesticides. The most likely EDI values for ethyl chlorpyrifos derived from Italian blood orange consumption are 0.01 and 0.006 mg/day calculated for 180 and 365 days, respectively. Considering the probability of the occurrence of ethyl chlorpyrifos, these EDI values are reduced to 2.6 x 10(-3) and 1.3 x 10(-3) mg/day, respectively. For methyl chlorpyrifos, the most likely EDI values are 0.09 and 0.04 mg/day, respectively; considering the probability of its occurrence, the EDI values decrease to 6.7 x 10(-3) and 3.4 x 10(-3) mg/day, respectively. The results confirmed that levels of pesticides in Italian Tarocco oranges derived from a known controlled chain of production are safe. Number of Volumes: 7 ISI Document Delivery No.: 457ZW 218.

In 2010, they reached a production of 503,000 tons which accounted for 99% of national production, and created profits over one billion dollars statewide. The major regions growing walnuts in California include the Sacramento Basin, San Joaquin Basin and Tulare Lake Basin. To maximize crop production, a large amount of pesticides was applied to control pests: The amount of active ingredient (AI) used in pesticide products exceeded 1000 tons annually in 1995-2009, which could have posed potential pollution to surface water. This study looked into both pesticide use and its potential impact on surface water from 1995 to 2009 on California walnuts, focusing on the pesticide categories of fungicides, insecticides and herbicides. A pesticide risk evaluation model, Pesticide Use Risk Evaluation (PURE), was applied in this study to quantitatively analyze potential impact of pesticide use on surface water. Results showed that among the three main basins, the Sacramento Basin had the highest fungicide risk intensity on surface water (annual average value: 978.25 R/ha, 42% and 358% higher than San Joaquin and Tulare Lake), due to a heavy use of copper hydroxide and maneb. San Joaquin had the highest insecticide risk intensity (973.73 R/ha, 33% and 56% higher than the Sacramento Basin and Tulare Lake) resulting mainly from chlorpyrifos, azinphos-methyl, chloropicrin, and malathion use. Herbicide showed a consistent low risk intensity (<50 R/ha) in all basins. The Mann-Kendall test showed fungicide and insecticide risk intensity presented a consistently decreasing trend in all basins, while herbicide risk intensity presented an increasing trend in Tulare Lake. A finer spatial scale analysis was conducted at township level (6Ă—6 mile 2 ) to assess the use and risk patterns in more details, the results of which are presented as GIS maps. Finally, based on some lab experiments observing pyrethroid use can cause mite outbreaks, a case study was carried out to examine the relationship between pyrethroid and miticide use on California walnuts and their potential impact on surface water. A developed model captured the relationship as the miticide use intensity is positively correlated with pyrethroid use intensity until it reaches a maximum value. Through a comprehensive pesticide use and risk analysis on California walnut, important conclusions are made. For example, pesticides such as copper hydroxide and chlorpyrifos have high toxicity in surface water. Our analysis indicates that if they were replaced by more environmentally benign pesticides - such as kaolin and petroleum oil - the overall risk scores and environmental impacts would decrease. These results can be useful to help local walnut growers make decisions on pesticide choices, and help regulators to make suggestions and integrated pesticide management on critical regions.

Farghaly, M. and El-Maghraby, S. Investigation of chronic toxicity of (14)C-fenitrothion and its degradation products on stored soybeans. 2009; 27, 1-6. Rec #: 13110 Keywords: FOOD Notes: Chemical of Concern: MLN Abstract: Abstract: Grains of soybeans were treated with the recommended dose of fenitrothion insecticide, 5 mg/kg, and double that dose, before storage for 30 weeks under ambient local conditions. During the storage period. the penetration and distribution of insecticide residues were studied. The amount of surface residues on stored soybeans, internal extractable and bound residues were determined. Surface residues were found to decrease with the increase in time of storage, whereas internal residues showed a gradual increase with time to reach 56%, 54% of applied doses after 30 weeks. The amount of bound residues inside the matrix showed a slow increase with time. Toxicity of the total internal residues of fenitrothion in stored soybeans was studied in mice through a sub-chronic feeding experiment for 3 months. The maximum inhibition in plasma and erythrocyte cholinesterase activity was 37% and 13% after the first month, respectively. Treated mice suffered from deterioration of hepatic and renal functions as indicated by the increase level of blood serum esterase's and blood urea nitrogen. Percentage increase in alanine aminotransferase (ALT) and aspartate aminotransferase (AST) was reached to about 62% and 55%, respectively as compared with control animals with the end of feeding period.

Assessment of Blood Flow Changes in Human Skin by Microdialysis Urea Clearance. 2011; 18, 198-204. Rec #: 13120 Keywords: HUMAN HEALTH Notes: Chemical of Concern: MLN Abstract: Abstract: P>Objective: The aim of this study was to evaluate the urea clearance technique for the measurement of drug-induced blood flow changes in human skin and compare it to two non-invasive techniques: polarization light spectroscopy and laser Doppler perfusion imaging. Methods: Fifteen microdialysis catheters were placed intracutaneously on the volar aspect of the forearms of healthy human subjects and were perfused with nitroglycerine, noradrenaline, and again nitroglycerine to induce local tissue hyperemia, hypoperfusion, and hyperemia, respectively. Results: Urea clearance, but not the other techniques, detected the changes in blood flow during changes in flow. The last hyperemic response was detected by all three methods. Conclusion: Urea clearance can be used as a relatively simple method to estimate blood flow changes during microdialysis of vasoactive substances, in particular when the tissue is preconditioned in order to enhance the contrast between baseline and the responses to the provocations. Our results support that, in the model described, urea clearance was superior to the optical methods as it detected both the increases and decrease in blood flow, and the returns to baseline between these periods.

Studies of the Interaction of Two Organophosphonates With Nanostructured Silver Surfaces. 2012 Oct 7; 137 , (19): 4448-4453. Rec #: 5610 Keywords: CHEM METHODS Notes: Chemical of Concern: MLN Abstract: Abstract: Electrochemical cycling of silver surfaces in the presence of the organophosphonates paraoxon and malathion leads to changes in the electrochemical response of silver and the formation of silver nanostructures. Adsorption of the organophosphonates onto the silver surfaces causes a significant reduction in the observed current response due to an increase in the charge transfer resistance. Surface enhanced Raman spectroscopy (SERS) measurements indicate that paraoxon adsorbs with no structural changes, while malathion decomposes and a thiophosphonate interacts with the surface. The SERS study of these adsorbates was carried out by changing the electrochemical conditions and the concentration of the organophosphonates. The size of the nanostructures greatly influences the SERS signal and it is observed that the strongest enhancement is observed for mid-sized nanostructures with a uniform thickness on the surface. The limit of detection was shown to be in the range of 10 nM to 10 pM for paraoxon and malathion, respectively. eng. Date completed - 2013-01-17. Date created - 2012-08-29. Date revised - 2013-01-25.

Inorganic and organic contaminants in sediments from an urban playa and associated toxicity among Hyalella azteca. 2012; 94, 1746-1757. Rec #: 13140 Keywords: SEDIMENT CONC Notes: Chemical of Concern: MLN Abstract: Abstract: Playa wetlands are important components of the Southern High Plains (USA) landscape as they are the major aquatic surface feature. Chemical contaminants associated with playas have been documented, particularly for grassland and agricultural watersheds, but not for playas in urban settings. The objectives of this study were to determine concentrations of inorganic and organic contaminants in sediments from an urban playa within the I-20 Wildlife Preserve and Jenna Welch Nature Study Center in Midland, TX, and evaluate toxicity of these sediments to Hyalella azteca. Concentrations of most trace elements were below sediment quality guidelines with exceptions of lead, cadmium, and arsenic. Concentrations of organic contaminants, particularly PAHs, DDT, DDE, and malathion, were above sediment quality guidelines at various locations within the playa. Decreased survival was observed among H. azteca exposed to sediment from a single location when compared those exposed to reference sediments. This location also produced maximum observed concentrations for five of seven trace elements, potentially due to its location at the lowest elevation within the playa. This study documented concentrations of contaminants in sediments of an urban playa associated with past and present land uses in its urban setting, including those from automotive emissions and historical pesticide use.

Reduction of the Movement and Persistence of Pesticides in Soil Through Common Agronomic Practices. 2011 Nov; 85, (8): 1375-1382. Rec #: 3050 Keywords: FATE Notes: Chemical of Concern: MLN Abstract: Abstract: Laboratory and field studies were conducted in order to determine the leaching potential of eight pesticides commonly used during pepper cultivation by use of disturbed soil columns and field lysimeters, respectively. Two soils with different organic matter content (soils A and B) were used. Additionally, soil B was amended with compost (sheep manure). The tested compounds were cypermethrin, chlorpyrifos-methyl, bifenthrin, chlorpyrifos, cyfluthrin, endosulfan, malathion and tolclofos-methyl. In soil B (lower organic matter content), only endosulfan sulphate, malathion and tolclofos-methyl were found in leachates. For the soil A (higher organic matter content) and amended soil B, pesticide residues were not found in the leachates. In addition, this paper reports on the use of common agronomic practices (solarization and biosolarization) to enhance degradation of these pesticides from polluted soil A. The results showed that both solarization and biosolarization enhanced the degradation rates of endosulfan, bifenthrin and tolclofos-methyl compared with the control. Most of the studied pesticides showed similar behavior under solarization and biosolarization conditions. However, chlorpyrifos was degraded to a greater extent in the solarization than in biosolarization treatment. The results obtained point to the interest in the use of organic amendment in reducing the pollution of groundwater by pesticide drainage and in the use of solarization and biosolarization in reducing the persistence of pesticides in soil.

Pesticide Residues in Portuguese Strawberries Grown in 2009-2010 Using Integrated Pest Management and Organic Farming. 2012 Nov; 19, (9): 4184-4192. Rec #: 2450 Keywords: CHEM METHODS Notes: Chemical of Concern: MLN Abstract: Abstract: Pesticides are among the most widely used chemicals in the world. Because of the widespread use of agricultural chemicals in food production, people are exposed to low levels of pesticide residues through their diets. Scientists do not yet have a total understanding of the health effects of these pesticide residues. This work aims to determine differences in terms of pesticide residue content in Portuguese strawberries grown using different agriculture practices. The Quick, Easy, Cheap, Effective, Rugged, and Safe sample preparation method was conducted and shown to have good performance for multiclass pesticides extraction in strawberries. The screening of 25 pesticides residue was performed by gas chromatography-tandem mass spectrometry. In quantitative validation, acceptable performances were achieved with recoveries of 70-120 and <12 % residual standard deviation for 25 pesticides. Good linearity was obtained for all the target compounds, with highly satisfactory repeatability. The limits of detection were in the range of 0.1-28 mu g/kg. The method was applied to analyze strawberry samples from organic and integrated pest management (IPM) practices harvested in 2009-2010. The results showed the presence of fludioxonil, bifenthrin, mepanipyrim, tolylfluanid, cyprodinil, tetraconazole, and malathion when using IPM below the maximum residue levels.

Fianko, Joseph R; Donkor, Augustine; Lowor, Samuel T; Yeboah, Philip O, and Fianko, Joseph R. Agrochemicals and the Ghanaian Environment, a Review. 2011 May; 2, (3): 221. Rec #: 6410 Keywords: REVIEW Notes: Chemical of Concern: MLN Abstract: Abstract: Agrochemicals are generally recognized as a significant factor in enhancing the ability to meet Ghana's need for sufficient, safe and affordable food and fiber, however, increased usage have led to environmental deterioration. In Ghana agriculture and public health sectors remain the major contributors of pollutants into the environment. This is a systematic review of studies done in Ghana to give an integrated picture of agrochemicals especially pesticides exposure to humans, animals, plants, water, soil/sediment and atmosphere in Ghana. Although the widespread usage of agrochemicals in Ghana has contributed immensely to increased food supply and improvement in public health, it has caused tremendous harm to the environment. Water bodies, fish, vegetables, food, soil and sediment have been found to be pesticide contaminated. There is considerable evidence that farmers have overused agrochemicals especially pesticides. It is evident from biological monitoring studies that farmers are at higher risk for acute and chronic health effects associated with pesticides due to occupational exposure. Furthermore the intensive use of pesticides involves a special risk of for field workers, consumers and unacceptable residue levels in exportable products may serve as barrier to international trade. This review will set the future course of action of different studies on agrochemical usage and pesticide exposure in Ghana. Keywords: Environmental Studies English. Date revised - 2011-07-01.

Development, Validation and Application of a Methodology Based on Solid-Phase Micro Extraction Followed by Gas Chromatography Coupled to Mass Spectrometry (Spme/Gc-Ms) for the Determination of Pesticide Residues in Mangoes. 2010 Apr 15; 81, (1-2): 346-354. Rec #: 7030 Keywords: CHEM METHODS Notes: Chemical of Concern: MLN Abstract: Abstract: A method was developed for the simultaneous analysis of 14 pesticide residues (clofentezine, carbofuran, diazinon, methyl parathion, malathion, fenthion, thiabendazole, imazalil, bifenthrin, permethrin, prochloraz, pyraclostrobin, difenoconazole and azoxystrobin) in mango fruit, based on solid-phase micro extraction (SPME) coupled to gas chromatography-mass spectrometry (GC-MS). Different parameters of the method were evaluated, such as fiber type, extraction mode (direct immersion and headspace), temperature, extraction and desorption times, stirring velocities and ionic strength. The best results were obtained using polyacrylate fiber and direct immersion mode at 50 degree C for 30 min, along with stirring at 250 rpm and desorption for 5 min at 280 degree C. The method was validated using mango samples spiked with pesticides at concentration levels ranging from 33.3 to 333.3 mu g kg super(-1). The average recoveries (n = 3) for the lowest concentration level ranged from 71.6 to 117.5%, with relative standard deviations between 3.1 and 12.3%, respectively. Detection and quantification limits ranged from 1.0 to 3.3 mu g kg super(-1) and from 3.33 to 33.33 mu g kg super(-1), respectively. The optimized method was then applied to 16 locally purchased mango samples, all of them containing the pesticides bifenthrin and azoxystrobin in concentrations of 18.3-57.4 and 12.7-55.8 mu g kg super(-1), respectively, although these values were below the MRL established by Brazilian legislation. The method proved to be selective, sensitive, and with good precision and recovery rates, presenting LOQ below the MRL admitted by Brazilian legislation. Keywords: Pollution Abstracts English.

Rec #: 5510 Keywords: MIXTURE Notes: Chemical of Concern: MLN Abstract: Abstract: The potential of zero valent iron (ZVI) for remediation of contaminated groundwater from an abandoned chemical disposal site was examined through batch and column experiments. The key contaminants were organophosphate pesticides but the chemical analysis also comprised additional 22 compounds including synthesis intermediates and degradation products of organophosphates. The ZVI treatment showed that all the contaminants were degraded with the exception of two diesters (phosphorothioates). The most rapid reduction was found for methyl parathion, ethyl parathion and malathion, which had first-order degradation rate constants on the order of 10(-3) min(-1).
