[Objectives] This study was conducted to investigate the pesticide residue status of bananas in Tangshan area and the dietary intake risk of consumers. [Methods] High-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was applied to detect 70 pesticide residues in 191 batches of banana samples extracted from Tangshan area, and chronic and acute risk assessments were conducted. [Results] Among the 191 batches of bananas, 172 batches of samples were detected to contain agrochemicals, with a detection rate of 90.05%. Seventeen agrochemicals were detected, accounting for 24.29% of the total agrochemicals tested. There was a phenomenon of multiple pesticide residues in a single sample, and high detection rates were found in carbendazim (49.21%), pro-chloraz (41.88%), pyraclostrobin (34.03%) and imidacloprid (30.37%). According to GB 2763-2021 National Food Safety Standards--Maximum Residue Limits for Pesticides in Food, the over-standard rate of imidacloprid was 17.8%; and the chronic and acute dietary risks of the 17 pesticide residues were all less than 100%. [Conclusions] The pesticide residues in bananas consumed by consumers on a daily basis do not pose unacceptable dietary risks. [ABSTRACT FROM AUTHOR]

[Objectives] This study was conducted to understand the status of pesticide residues and dietary intake risk of Chinese chives in Tangshan area. [Methods] Sixty eight kinds of pesticide residues in 415 Chinese chive samples collected from Tangshan area were qualitatively and quantitatively determined by high -performance liquid chrom atograp hy -tan dem mass spectrometry (HPLC-MS/MS) and gas chromatography (GC) in 2020. [Results] The results showed that 41 kinds of pesticide residues were detected in the 415 Chinese chive samples, and the detection rate was 69.4% (288/415), and there was a combination of pesticides in many samples. According to the National Food Safety Standard--Maximum Residue limits of Pesticides in Food (GB 2763-2019), the residues of 12 pesticides exceeded the maximum residue limits (MRLs), and the unqualified rate was 38. 07% (158 / 415). The highest detection rate of clothianidin was 41. 20% (171/415), but there was no MRL in GB 2763-2019. The next was procymidone, the detection rate of which was 35.42% (147/415), and the over-standard rate was 30.12% (125/415). Forbidden and restricted pesticides were detected in some samples. According to the dietary exposure risk assessment, the NEDI/ADI values were all less than 1 and the intake risk was within acceptable range. In Tangshan area, the types of pesticides used in Chinese chive production are complex, and there are risks of multi-residue pollution and use of banned and restricted pesticides and unregistered pesticides. It is suggested that routine monitoring of pesticide residues and management of pesticide use should be strengthened to ensure the quality and safety of agricultural products - [Conclusions] This study provides a theoretical basis for the safe production of Chinese chive and the standardized and rational use of pesticides.
