Residue and Risk Assessment of Propiconazole and Epoxiconazole in Apple
摘要
Abstract
In order to determinate the dietary risk of using propiconazole and epoxiconazole for apple in picking period,the residue test,dietary exposure and risk assessment were conducted by treating apples with 1 000 and 500 times liquid of 25% propiconazole emulsion in water (250 and 500 mg a.i./kg),333 and 167 times liquid of 12.5% epoxiconazole emulsion in water (375 and 750 mg a.i./kg)respectively.The results showed that the original accumulation of the four treatments were 3.37,4.72,1.61 and 2.95 mg/kg respec-tively with the half -life as 7.5,7.8,10.8 and 10.5 days,respectively.The results of dietary exposure esti-mation showed that different age groups had different risk quotient;the risk quotient of children was obviously higher than that of adults.The risk quotient of double application rate was obviously higher than that of the normal rate.During 0 ~45 days after treatments,the risk quotient for seven kinds of typical persons was below 12.0 with the application of 1 000 and 500 times liquid of 25% propiconazole emulsion in water,and below 27.0 with the application of 333 and 167 times liquid of 12.5% epoxiconazole emulsion in water.In conclu-sion,rational use of propiconazole and epoxiconazole for apple in picking period had lower dietary health risk to consumers.关键词
