In this work, optimized methods for cleaning, infusing reference standards, and polymer extraction are reported along with field comparisons of several silicone materials for polycyclic aromatic hydrocarbons (PAHs) and pesticides. In a final field demonstration, the most optimal silicone material is coupled with LDPE in a large-scale study to examine PAHs in addition to oxygenated-PAHs (OPAHs) at a Superfund site. OPAHs exemplify a sensitive range of chemical properties to compare polymers (log Kow 0.2-5.3), and transformation products of commonly studied parent PAHs. On average, while polymer concentrations differed nearly 7-fold, water-calculated values were more similar (about 3.5-fold or less) for both PAHs (17) and OPAHs (7). Individual water concentrations of OPAHs differed dramatically between silicone and LDPE, highlighting the advantages of choosing appropriate polymers and optimized methods for pollutant monitoring.&lt;/p&gt;

Passive sampling devices (PSDs) are technologically simple analytical tools that sequester and concentrate bioavailable organic contaminants from the environment. Scientists from Oregon State University and the Centre Régional de Recherches en Ecotoxicologie et de Sécurité Environnementale (CERES) in Senegal developed a partnership to build capacity at CERES and to develop a pesticide-monitoring project using PSDs. This engagement resulted in the development of a dynamic training process applicable to capacity-building programmes. The project culminated in a field and laboratory study where paired PSD samples were simultaneously analysed in African and US laboratories with quality control evaluation and traceability. The joint study included sampling from 63 sites across six western African countries, generating a 9000 data point pesticide database with virtual access to all study participants.&lt;/p&gt;

&lt;p&gt;Organizations and developing countries that attempt to assess pesticides and other environmental contaminants face many challenges of how to measure them, such as, the remoteness of sites and subsequently the difficulty of transportation and stability of chemicals in samples from these sites.&amp;nbsp; The Sahel region of Western Africa has many highly engineered agriculture-based irrigated systems that generally have three cropping cycles per year.&amp;nbsp; The need to assess changes in contaminants at these sites requires tools that can characterize contaminants at high spatial and temporal resolution.&amp;nbsp; Modification of farming pest management practices face the challenge of how to measure success; how to assess the changes in bioavailability of contaminants.&amp;nbsp; They need quantitative tools that can characterize contaminants and predict their risk to local organisms and humans.&amp;nbsp; To address these issues we have further developed passive sampling devices (PSDs) that can sequester thousands of bioavailable chemicals.&amp;nbsp; These devices can help organizations and developing countries to evaluate changes in pest management that may produce or release chemicals.&amp;nbsp; PSDs can help organizers characterize exposure more accurately.&amp;nbsp; We are using PSDs to capture relevant non-polar and semi-polar pesticides and other chemicals of interest at multiple sites in Western Africa.&amp;nbsp; PSDs do not require power, transport easily and are easily extracted with organic solvent. We deployed PSDs in irrigation canals at seven agricultural sites in Senegal, Mali, and Mauritania agricultural stations. We were able to screen the PSD extracts for nearly 1,200 potential contaminants with gas chromatography mass spectrometry through the use &amp;nbsp;of libraries we have further developed based on software, including automated compiled mass spectral de-convolution and identification system libraries that contain numerous classes of chemicals of concern (pesticides, PCBs, PAHs, pharmaceuticals, industrially related chemicals, etc.). The results for all sites combined showed positive hits of six PCB congeners, 11 pesticides, 21 PAHs and two legacy pesticides including ethiolate, p&amp;rsquo;p&amp;rsquo; DDD and its breakdown products.&amp;nbsp; Furthermore the compound pentachloroanisole a breakdown product of pentachlorophenol was detected in Mauritania. PSDs coupled with GC-MS screening tools offer a powerful technology to identify persistent organic pollutants present at agricultural sites in three countries in the Sahel region of Western Africa.&amp;nbsp;&lt;/p&gt;
