Objective To detect and analyze the residue conditions of 57 kinds of pesticide in commercially available fruits in Handan Area from 2020 to 2024 and assess the health risks of pesticide residues for local residents. Methods Followed QuEChERS extraction, samples were analyzed using liquid chromatography-mass spectrometry and gas chromatography-mass spectrometry. Chronic dietary exposure was assessed via a Monte Carlo simulation-based risk model, whereas acute risk was determined by the acute reference dose. Results The p detection rate of pesticide types in 80 fruit samples was 28.1% with an overall item detection rate of 1.12% and overall sample detection rate of 33.8% in 80 fruit samples. Dimethoate residues exceeded national standards in 6 cherry and 3 jujube samples. Two or more pesticides were detected in 16.2% of the samples. No highly or extremely toxic pesticides were detected. The chronic dietary intake risk of dimethoate was 1.81, exceeded the safe range, while the chronic dietary intake risk of other pesticides were within acceptable limits. The hazard index value was 1.87, exceeded the safe range. Acute dietary risks for all detected pesticides were within safe ranges. Dimethoate and endosulfan were identified as higher-risk pesticides in both acute and chronic assessments. Conclusion The dietary intake risk of pesticide residues in Handan City (2020—2024) is generally within safe limits. However, there are cases of dimethoate exceeding the standard and multiple pesticides detected in the same sample. Dimethoate posed chronic dietary intake risk and the relevant authorities need to maintain ongoing attention.
