Implication

Comparative modeling analysis reveals persistence and transport patterns for current-use pesticides, indicating the need for updated regulatory screening frameworks.

Key Points

To evaluate the long-term environmental persistence and long-range transport potential of current-use pesticides using standard screening criteria and multimedia fate modeling.
Analyzed regulatory simulation test data for 45 active ingredients of current-use pesticides.
Evaluated chemicals against Stockholm Convention persistent organic pollutant criteria and calculated overall persistence and characteristic travel distances using a multimedia environmental fate model.
Under Stockholm Convention criteria, two of 45 pesticides met screening benchmarks for both persistence and long-range transport potential, 13 met persistence criteria alone, and one met transport potential alone.
Multimedia modeling showed that three chemicals exceeded overall persistence boundaries, none exceeded air travel distance criteria, and 19 chemicals were transported over longer distances in water than in air.
