What opportunities for training and professional development has the project provided?Assessing Agrochemical Toxicity-Exposure to Humans & Communicating Risks: One graduate student received his MS. Effects of Agrochemicals on Pollinators: Two technicians and Three undergraduates have received laboratory training for assessing pesticide residues on beehive materials. How have the results been disseminated to communities of interest?The results from both areas have been widely disseminated through publication in the peer-reviewed literature and presentations given at various regional, state, national, and international venues in 2016.

Assessing Agrochemical Toxicity-Exposure to Humans & Communicating Risks: Off-target soil fumigant emissions remain a primary source of inhalation exposure to individuals & communities at urban/agricultural interfaces. The combined efforts from W-2045 state AES (UC-Riverside, FL, WA) & USDA-ARS research have advanced & put into practice containment technologies that appreciably reduce off-target fumigant movement while providing efficacious soil-borne pathogen/nematode control. These improvements in soil fumigant retention has led to substantial reduction of state & national no treatment buffer zones preserving production acreage while benefiting growers & protecting human & environmental health. Inhalation exposure concerns, however, are not limited to the parent fumigant; atmospheric transformation products are sometimes more toxic. We have conducted basic research and developed air sampling systems to measure toxicologically relevant fumigant by-products in air. This research will aid multi-state public health agencies for ascertaining the effectiveness of putative fumigant emission reducing technologies for human health & make available a mechanism for communicating fumigant exposure risks to the community. In 2016, a publication on the influence of temperature on the fumigant MITC was published by our group. Effects of Agrochemicals on Pollinators: Pollinator health will remain an on-going US concern among beekeepers, regulatory agencies, & the public. Although there is no consensus about the cause or combination of causes for Colony Collapse Disorder, certain agricultural pesticides that include the nitroguanidine-substituted neonicotinoid insecticides imidacloprid, clothianidin, thiamethoxam, & dinotefuran have been implicated as contributing to colony losses. We have examined neonicotinoid residues in/on important hive materials (brood wax & stored pollen from bee hives collected in over 150 landscape locations throughout Washington State. This research was published in 2016 and on-going research will increase our understanding of field relevant residue exposures to foraging honey bees that predominately visit vegetation in urban & rural landscapes.
