Neonicotinoid insecticides (NNIs) can harm non-target species. This study examines NNIs’ distribution, sources, human exposure risks, and ecological risks in the Qiantang River’s water sediment. NNIs concentrations ranged from 8.92 to 88.0 ng/L 0.55 16.6 ng/g dw The showed a trend of middle reaches > lower upper reaches. Agricultural activities were main source, followed by wastewater treatment plants. Infants had highest intake, with daily intake 15.4 ng/kg body weight, about 5.4-times higher than adolescents. Using species sensitivity distribution relative potency factor, acute chronic toxicity thresholds for aquatic organisms estimated at HC5 values 3636 40 ng/L, respectively. Species trophic levels more sensitive NNIs. While fauna are low, prolonged poses potential health. These findings contribute enhancement regulatory framework serve as reference policymakers formulating pollution management strategies, thereby advancing sustainable development resources region.
