Technical Abstract: Accurate determination of predicted environmental concentrations (PECs) is a continuing and often elusive goal of pesticide risk assessment. PECs are typically derived using simulation models that depend on laboratory generated data for key input parameters (t1/2, Koc, etc.). Model flexibility in evaluating use scenarios makes them ideal tools for risk assessment; however, poor correspondence between PECs and field based measurement is common and often leads to a lack of confidence in model results. Environmental fate studies that bridge laboratory and field-based investigations are needed to close this divide. In this presentation we will discuss our recent studies and make proposals for a way forward.
