Different distribution patterns and potential risks of pesticide residues between soils and sediments: a case study in Lake Taihu Ecological Conservation Area.

ABSTRACT: Pesticides can migrate and accumulate across environmental compartments, necessitating multi-medium risk assessments to ensure sustainable development and safeguard human health. Although soils and sediments are recognized as ultimate sinks for pesticides, differences in their distribution patterns and associated ecological risks remain poorly understood, posing challenges for targeted pesticide management. In this study, we analyzed the temporal and spatial distribution of 39 various historically-used and currently-used pesticides in both farmland soils and their nearby river sediments collected from the Lake Taihu Ecological Conservation Area (TECA), China. A total of 9 and 7 types of pesticides were found in soils and sediments, respectively, which were dominated by p,p'-DDE (in average
