To understand the status of fungicide residues in fruits and vegetables sold in Xingtai City, and conduct acute and chronic dietary intake risk assessments on the detected fungicide residues in fruits and vegetables.
A total of 399 samples of fresh fruits and vegetables were collected in Xingtai City from 2021 to 2025. Liquid chromatography-tandem triple quadrupole mass spectrometry was used to detect 10 kinds of common fungicides, and the percentage of acute reference dose and the percentage of acceptable daily intake were calculated to conduct acute and chronic dietary intake risk assessments.
From 2021 to 2025, the detection rate of 10 kinds of fungicides in fruits and vegetables sold in Xingtai City was 39.35%, and the non-compliance rate of samples was 0.25%. Fungicide residues were detected in 8 categories of vegetables and 4 categories of fruits. Among vegetables, the detection rate of leafy vegetables was the highest, reaching 56.47%; and among fruits, the detection rate of stone fruits was the highest, reaching 50.00%. Among the 10 monitored fungicides, dimethomorph had the highest detection rate of 24.56%. The calculated ranges of acute and chronic dietary intake risks were 0.2016%–84.1602% and 0.1264%–47.2337%, respectively, both of which were less than 100%.
From 2021 to 2025, the overall situation of 10 kinds of fungicide residues in fruits and vegetables sold in Xingtai City,Hebei Province is good, and the detected fungicide residues are within the acceptable range for the safety status of fruits and vegetables sold in Xingtai City. However, there are varying degrees of fungicide contamination and mixed use in fruits and vegetables. It is necessary to focus on leafy vegetables, solanaceous vegetables, stone fruits and other categories. Additionally, the intake risk of consumers in the 2–10 years old children group is significantly higher than in other age groups, which requires particular attention.
