| 摘 要： | 对红小豆中精喹禾灵及其代谢物的最终残留进行测定,并评估其长期和短期膳食摄入的风险。结果表明:以0.3~0.6 mL/m^2施药浓度施药2~3次,多种采摘间隔下,红小豆中精喹禾灵残留量为0.03~1.07 mg/kg,精喹禾灵酸残留量为0.05~1.20 mg/kg。红小豆中精喹禾灵及其代谢物的长期膳食摄入风险商和短期膳食摄入风险商分别为1.98%~19.70%,0.50%~1.30%,膳食摄入风险低。

| Abstract: | In order to evaluate the long-term and short-term dietary intake risk of quizalofop-p-ethyl and quizalofop-p-acid in adzuki bean, the final residue of them was determined. Using the application concentration of 0.3~0.6 mL/m2, the application frequency of 2~3 times with various picking intervals, the residue of quizalofop-p-ethyl in adzuki bean was 0.03~1.07 mg/kg, and that of quizalofop-p-acid was 0.05~1.20 mg/kg. The long-term dietary intake risk quotient (RQc) and short-term dietary intake risk quotient (RQa) were 1.98%~19.70% and 0.50%~1.30%, respectively. |
