Pollution analysis and dietary risk assessment of 15 organophosphorus pesticides in 9 medicinal and edible materials were carried out to provide basic data support for the development of rapid screening method for pesticide residues in traditional Chinese medicine.Detection rate and over standard rate were used for pesticide residue analysis.Chronic and acute dietary exposure assessments were calculated for dietary risk assessments.Citri Reticulatae Pericarpium and Gardeniae Fructus had the highest number of pesticides detected,with a total of 8 pesticides detected and 3 of them were prohibited pesticides.Among the banned pesticides,phorate was the most detected,which was detected in 5 traditional Chinese medicine and the detection rate was up to 100%in Angelicae Sinensis.Chlorpyrifos was detected in 6 traditional Chinese medicine,and the detection rate was up to 100%in Lonicerae Japonicae Flos.The over standard rate of the prohibited phorate in Angelicae Sinensis was as high as 69.05%,and the over standard rate of profenofos in Citri Reticulatae Pericarpium was 25.45%.Organophosphorus pesticides in 9 medicinal and edible materials were detected to varying degrees,and the pollution phenomenon was common and the over standard rate was high.Although the current dietary risk assessment results of acute and chronic dietary dietary risk were within the acceptable range,the cumulative risk of pesticide residues was increasing,which would inevitably affect the quality of traditional Chinese medicine and endanger human health.Therefore,it is necessary to scientifically regulate the use of pesticides,and adopt favorable regulatory means to control the quality of traditional Chinese medicine.
