Risk Assessment and Hazard Rank of Pesticide Residues in Jujube from Xinjiang

To clear the hazard and rank of pesticide residues in jujube from Xinjiang,in this paper,124 samples of jujube from Xinjiang 10 producing areas were collected,residues of 37 pesticides in samples were determined,on the basis of above,through chronic dietary intake risk and acute dietary intake risk,the hazard of residues pesticides on jujube quality safety of pesticide residues were assessed;and using the risk matrix,the residues pesticides were ranked. The results showed that 11 pesticides were detected,the%ADI(chronic dietary intake risk)of residues pesticide were lower than 100%;the%ARfD(acute dietary intake risk)of 10 residues pesticide were lower than 100%;comparing the other residues pesticides,the risk values of pyridaben,chlorpyrifos,difenoconazole,cyhalothrin,cyoermethrin,fenpropathrin were higher,greater than 12.05.By above,the intake risks of 6 pesticides residues in Xinjiang jujube were low,pyridaben,chlorpyrifos,difenoconazole,cyhalothrin,cyoermethrin,fenpropathrin should be focused on.
