PRI is an environmental consulting firm providing research, analysis, technical services and expert consulting on the chemistry and toxicology of pesticides. We conduct human and ecological risk assessment, develop tools to assess the relative risks associated with use of different pesticides, provide guidance and input on pesticide regulation and policy, and develop integrated pest management (IPM) approaches that solve pest problems with minimum pesticide use. PRI also conducts environmental monitoring, with a focus on air, water, beehive matrices, and other environmental media.
