摘　　要：用气象色谱法试验研究施保功5096WP浸芒果防腐保鲜后的残留消解动态及安全性评价结果表明,施保功处理芒果后其原始沉积量广西为0．8929～1．0433mg／kg,广东为0．8506～0．9522mg／kg,半衰期(T/2)广西为8～9d,广东为8d,经30d降解率>92％。以1000～2000mg／kg施保功浸芒果,储藏期10～30d,其果肉中施保功残留量广西为0．0003～0．0082mg／kg,广东为0．0003～0．0089mg／kg;全果中施保功残留量广西为0．0037～0．1171 mg／kg,广东为0．0030-0．1179mg／kg。用施保功50％WP1000～2000mg／kg浸芒果保鲜,间隔10d以上其残留量均<2mg／kg,说明施用施保功是安全的。Residual dynamics in stored mango treated by 50 % WP sporgon were analyzed by GC with ECDN163. The result shows that the sporgon aggradational amounts of the sporgon-treated stored mango are 0.8929- 1.0433mg/kg in Guangxi Province and 0.8506-0.9522 mg/kg in Guangdong Province. The periods of half-lives are 8- 9 days in Guangxi and 8 days in Guangdong,respectively. More than 92 % sporgon is degraded 30 days after the sporgon is applied. The last residues are 0. 0003- 0. 0082mg/kg in Guangxi and 0. 0003- 0. 0089 mg/kg in Guangdong in mango flesh, and 0.0037-0. 1171 mg/kg in Guangxi and 0.0030- 0.1179 mg/kg in Guangdong in whole mango （flesh and skin）after the mangos are treated with 1000- 2000mg/kg sporgon and stored for 10- 30 days. It is suggested that the application of 1000-2000mg/kg 50 0/6 WP sporgon on the stored mango with at least 10 days interval between two applications is safe to conserve mango with less than 2mg/kg residual in the fruit.
