[目的]监测噻嗪酮在柑橘和土壤中的残留量。[方法]采用气相色谱法测定噻嗪酮在柑橘和土壤中的残留。[结果]噻嗪酮在柑橘全果中的平均回收率为96.17%～97.38%,变异系数为6.10%～9.07%;在果肉中的平均回收率为95.24%～105.46%,变异系数为3.30%～6.01%;在果皮中的平均回收率为88.76%～93.64%,变异系数为5.12%～6.27%;在土壤中的平均回收率为97.79%～104.3%,变异系数为2.45%～9.21%。噻嗪酮在柑橘和土壤中的消解动态以及最终残留结果表明,在湖南长沙、浙江杭州和贵州贵阳3地柑橘中的消解半衰期分别为7.65、7.64、8.40 d,在土壤中的消解半衰期分别为13.75、9.97、10.18 d。[结论]在柑橘上使用25%噻嗪...

[Objective]The paper was to detect the residue of buprofezin in citrus and soil.[Method]Gas chromatography（GC） method was used to measure the residue of buprofezin in citrus and soil.[Result]The average recovery rate of buprofezin in entire citrus fruit was 96.17%-97.38%,and the variation coefficient was 6.10%-9.07%;the average recovery rate in pulp was 95.24%-105.46%,and the variation coefficient was 3.30%-6.01%;the average recovery rate in peel was 88.76%-93.64%,and the variation coefficient was 5.12%-6.27%;the average recovery rate in soil...
