15.1Step 3: Collecting and compiling data from key sectorsThe inventory team needs to investigate if the following exist in the country:
The following types of numerical data need to be collected and compiled in the inventory:
Data collection approaches will vary from country to country based on the data gathered in steps 1 and 2; they may be by estimations, using statistical data or possibly measurements. Estimations of POP-PBDEs quantities in the country for major POP-PBDEs former use sectors are provided in chapters 4 and 5. Measurements could be performed by analytical screening on representative samples (see Guidance on Screening and Analysis of POPs in Articles and Products). The focal sectors to be investigated in the national inventory fall under four key areas:
In addition, data collected for the first three key areas will form the basis for the preliminary inventory of the contaminated sites, waste and stockpiles. 15.2Step 4: Managing and evaluating the data15.2.1Data managementSince Parties have different designs and levels of legal framework, political organization and economic support for environmental management, different methodologies will be applied in the data gathering process as described in section 3.3. The management of collected data should be done as consistently and as transparently as possible. During the data processing, all the assumptions and conversion coefficients adopted as a result of expert judgement, where needed, should be noted/recorderd and mentioned when the results are presented. Before the inventory starts, all the data formats including questionnaire survey formats should be determined to anchor the consistency of the data collection as much as possible. If some data conversions and estimations are done by stakeholders, the inventory team must provide training on how to estimate the amount of POP-PBDEs and how to fill out the questionnaire. This will reduce the possibility of errors during the data management activities. Estimations will be needed to provide the total quantities in a country. Estimations are a valuable tool for providing the data needed when resources are limited. Since direct measurements of POP-PBDEs in products and articles are resource intensive, a preliminary inventory could be fully based on estimations in many cases (see section 3.2).
The evaluation includes identification of the following:
important elements in this evaluation step are to identify any gaps and limitations, and the measures needed to make the inventory more complete. Other ways to involve the stakeholders and other data collection strategies (see steps 2-4) could then be considered. A gap analysis in the evaluation of the initial assessment or preliminary inventory could result in the need to contact some of the stakeholders again to get more information or identify other stakeholders to be contacted to help fill the gaps. For inventory sectors with limited information, information campaigns and stakeholder meetings or workshops may be a necessary measure. In some cases, government regulations may be required to ensure that stakeholders report their holdings, cooperate with the national authorities and engage in the national inventory. To draft a regulation and make it come into force can sometimes require a long time (an year at a minimum in some places). Gaps, limitations and necessary actions to complete the inventory will also be valuable information for the NIP, especially for developing countries with need of financial support for their inventory. It is important for developing countries to identify whether and what technical and financial support will be necessary to complete the inventory. Even if the inventory is very incomplete, the NIP is expected to provide information on gaps and the limitations of a country's resources and capacities ― information that is useful to identify technical and financial needs. It is also important to identify whether the current situation meets the requirements of the Convention, including the actions needed to fulfil the obligations in the NIP, i.e. elimination of POP-PBDEs without specific exemption. Information on BAT/BEP measures are provided in the PBDE BAT/BEP Guidance. The inventory will also require revision at a later stage when the action plan is updated. This can also be done using the strategies described in this guidance.
