To explore how organochlorine pesticides (OCPs) are perpetual in soils and the risk they may bring, Ningbo, a city with an extensive usage history of OCPs, was selected as case to investigate. Sixty-nine agriculture were taken from 0–20 cm layers, then OCPs analyzed, assessment performed. Results indicate five detected agricultural soils, total concentrations ranging below detection limits 43.08 µg·kg−1 average value 15.58 µg·kg−1. Among them, δ-Hexachlorocyclohexane (δ-HCH) p, p’-Dichlorodiphenyltrichloroethane (p, p’-DDT) primary contributors residual contamination levels. The health indicates that even at maximum exposure levels, non-carcinogenic (1.71 × 10−4) carcinogenic (5.97 10−8) study area significantly thresholds 1 10−6, respectively. Monte Carlo simulation further confirms 95th percentile values for risks (3.39 10−4 1.23 10−7) remain well these limits, suggesting posed by adults negligible. Subsequent ecological revealed vast majority (73.91%) soil samples exhibited medium-low risk, dichlorodiphenyltrichloroethane (DDTs) being contributor risk. Our findings strengthen view although have been banned long time, residuals concern, more effective control methods should be used mitigate them.
