Randomized trial evaluates chronic effects of lufenuron on Daphnia magna, indicating significant adverse impacts.

This study aims to assess the chronic toxicity of lufenuron in the aquatic organism Daphnia magna through various biological responses.
Three lufenuron concentrations (0.01, 0.025, and 0.06 µg/L) were tested over 21 days.
Physiological, biochemical, and transcriptional responses were analyzed.
Survival, body length, molting frequency, heart rate, and reproductive performance were assessed.
Chronic exposure resulted in decreased survival, body length, molting frequency, and heart rate.
Reproductive performance showed a reduction in total offspring per female and a delay in the first brood.
Biochemical changes included increased MDA levels and elevated SOD and CAT activities, with decreased GST activity.

Dane et al. (2026) studied this question.
