Abstract: 【Objective】To clarify the influence of pesticide types and residues on Xinjiang pepper,and explore the types and risk levels of pesticide residues in Xinjiang pepper.【Methods】52 samples from 9 counties（cities） in Xinjiang in 2023 were taken as research objects. Gas chromatography-mass spectrometry and liquid chromatography-mass spectrometry were used to detect pesticides residues in peppers. Acute and chronic dietary intake risk analysis were conducted to evaluate the level of harm of detected pesticide residues to pepper quality and safety.【Results】A total of 29 kinds of residual pesticides were detected in 52 samples,including 4 kinds of restricted and prohibited pesticides.The chronic dietary intake risk（%ADI） value of all pesticide residues was 0.000 000 01%-0.001 425 60%,and the acute dietary intake risk（%ARfD） value was 0.007 613 333%-19.820 044 440%,which was much lower than 100%. It indicated that the chronic and acute dietary risks of pesticide residues were extremely low and at a safe level. According to the analysis of the pesticide residue risk index,there were no high-risk samples among the 52 samples,only 4 medium risk samples,and the rest of the samples were at low risk level or below.【Conclusion】The overall risk of pesticide residue in Xinjiang pepper is relatively low,and the quality and safety situation is generally good,but it is still necessary to strengthen the standardized use and control of pesticides in the future.
