Implication

Randomized trial assesses ecological risks of six pesticides in farmland and aquatic ecosystems, highlighting potential impacts on non-target organisms.

Key Points

Evaluate ecological risks posed by six pesticides to farmland and surface water ecosystems using toxicity data.
Constructed species sensitivity distribution models based on toxicity data for terrestrial and aquatic organisms.
Calculated hazard concentration (HC5) values for pesticides in terrestrial ecosystems.
Assessed ecological risk using hazard quotient (HQ) values for non-target organisms.
HC5 values for bifenthrin and pymetrozine exceeded the trigger threshold of 5, indicating significant risks.
Acute toxicity HC5 values ranged from 1.0 × 10–6 to 29.883 mg L–1 for aquatic organisms.
Findings validate the need for careful pesticide application to mitigate ecological risks.
