While diamide insecticides (DAIs) are new alternatives to conventional pesticides with improved selectivity, their environmental footprint needs an investigation. To that end, a nationwide study published in Environmental Chemistry and Ecotoxicology created a pollution snapshot to elucidate the widespread occurrence of DAIs in rivers across nine major Chinese basins, "We found four DAIs across rivers in 47 Chinese cities," shares corresponding author Yanhao Zhang. "The compounds were found at concentrations from below detection limit to 119 ng/L, with a national median total concentration of 40 ng/L." Cyantraniliprole (CYTP) was the predominant contaminant, with a median concentration of 17 ng/L and a 100% detection frequency. "The chemical composition patterns varied by regions," says Zhang. "CYTP contributed most in southern basins, while broflanilide (BFA) made a larger contribution in northern basins." Local crop-planting patterns and crop-specific pesticide-use potentially shaped the regional pollution signatures. Land-use and meteorological variables did could not explain the differences of nationwide distribution. Notably, there was a mismatch between concentration and ecological risk. "BFA was not the most abundant pollutant, yet it became the main screening-level driver for the benthic midge Chironomus dilutus because its species-specific chronic effect threshold was much lower," shares Zhang. "BFA screening RQs exceeded 1...

Background and Aims There is little epidemiological evidence linking the exposure of organophosphate pesticides (OPs) to liver function or liver injury in the general population. We used data from t...
