Safety Evaluation of Pesticide Residue in Five Fruits by Dietary Risk Index

Abstract

In order to determine the residual characteristics of pesticides in fruits and their effects on human health, monitoring of pesticide residues were conducted in apples, peaches, pears, grapes and citrus from the major cultivation areas in 2010. Safeties of the pesticides detected from the fruits were evaluated using the amounts of pesticide residue detected and dietary risk index (DRI). Samples were taken from 4-5 major fruit cultivation areas and then pesticide residues in the test fruits were analyzed with a liquid chromatographymass spectrometry (LC-MS/MS). Mean residue levels of the pesticides in fruits were 0.001-0.144 mg/kg. The DRIs were 0.55 for apple, 0.066 for peach, 0.008 for pear, 0.025 for grape, and 0.37 for citrus, respectively. The results indicated that the amounts of pesticide residues in domestic fruits might be safe, considering the regulatory concerning level 1.0 Key words

Suppression of Melanose Caused by Diaporthe citri on Citrus Leaves Pretreated with Bio-sulfur

“…Imprudent application of fungicides may cause high residue of fungicide in the crop product. Thus, new protection strategy which has less risk by misuse of systemic fungicide needs to be developed (Lee et al, 2014a). …”
