ABSTRACT Pesticide spray drift is potentially a significant source of exposure to off‐target, adjacent aquatic habitats. To estimate the magnitude pesticide from aerial or ground applications, regulatory agencies in North America, Europe, and elsewhere rely on models predict deposition for risk assessments. Refined assessments should ultimately depend best‐available data modeling. However, when developing lower tier “screening” designed indicate whether further refinement needed, regulators...
To reduce pesticide exposure to nontarget organisms in the United States (US), mitigations are being proposed a priori for regulatory compliance. Consequently, agricultural best management practices (BMPs) runoff, Environmental Protection Agency's Endangered Species Act (ESA) workplan [USEPA. ESA Workplan Update: Nontarget Mitigation Registration Review and Other FIFRA Actions, 2022. https://www.epa.gov/system/files/documents/2022-11/esa-workplan-update.pdf (accessed Feb, 2023)], were...
Abstract The occurrence of some species listed under the United States' Endangered Species Act in agricultural landscapes suggests that their habitats could potentially be exposed to pesticides. However, potential effects from such exposures on populations are difficult estimate. Mechanistic models can provide an avenue estimating impacts populations, considering realistic assumptions about ecology species, ecosystem it is part of, and within habitat. In present study, we applied a hybrid...
Rising world population and changing diets are increasing the need for efficient effective food fiber production. Pesticides used across US to control pests improve yield quality, but these benefits offset by their potential reach possibly impact aquatic or terrestrial ecosystems. Regulatory agencies rely on prospective exposure models that often start with conservative simplifying assumptions refined additional information if needed. The USEPA ecological risk assessment framework pesticides...
Decision-making for pesticide registration by the US Environmental Protection Agency (USEPA) relies upon crop-specific scenarios in a tiered framework. These standard modeling are stated to represent "…sites expected produce runoff greater than would be at 90% of sites given crop/use."
