摘要
采用田间试验方法,应用HPLC法测定了阿维菌素在水稻水、土壤及稻米中的残留。结果表明:阿维菌素在稻田水、土壤及稻米中的平均添加回收率分别在85.51%～87.98%、78.57%～83.09%、82.74%～86.80%之间。阿维菌素的最小检出量为4.824×10-10g,水、土壤、稻米中阿维菌素的最低检测浓度分别为0.001 mg/kg、0.014 mg/kg、0.01 mg/kg。该药属易分解农药(T1/2<30 d),按推荐使用剂量使用时收获的稻米是安全的[1]。
A field experiment was conducted to reveal the residue of Abamectin in water,soil and rice.The results showed that the recovery rate in the wate,soil and rice were 85.51%-87.98%,78.57%-83.09%,82.74%-86.80% respectively.The minimum detectable limits of the method was 4.824×10^-10 g.The limit of quantification was 0.001 mg/kg for water,0.014 mg/kg for soil and 0.01 mg/kg for rice.It was suggested that Abamectin belonged to non-persistent pesticides（T1/230 days）.
