| 为了筛选防治芹菜上重要害虫的替代药剂,在上海市及银川市开展5%吡虫啉颗粒剂、0.5%阿维菌素颗粒剂及5%氯虫苯甲酰胺悬浮剂在芹菜上的田间试验,通过液相色谱-串联质谱法检测3种农药在芹菜上的残留量,并分别对3种农药进行膳食暴露风险评估。结果表明,5%吡虫啉颗粒剂、0.5%阿维菌素颗粒剂及5%氯虫苯甲酰胺悬浮剂分别以推荐剂量施用于芹菜后，收获期吡虫啉及阿维菌素在芹菜上最大残留量分别为0.97 mg/kg及0.01 mg/kg，氯虫苯甲酰胺安全间隔期内（1 d）在芹菜上的最大残留量为5.24 mg/kg，均低于其在芹菜上的最大残留限量值。中国居民摄入吡虫啉、阿维菌素、氯虫苯甲酰胺的慢性暴露风险(%ADI)最大值为5.17%,急性暴露风险(%ARfD)最大值为11.20%,均远低于100%,膳食暴露风险低。结果表明吡虫啉、阿维菌素、氯虫苯甲酰胺可替代高毒农药用于芹菜上关键虫害的防治。 |

| The objective of this study was to discover alterative insecticides for celery (Apium graveolens var. dulce). Residue experiments of imidacloprid 5% GR, abamectin 0.5% GR and chlorantraniliprole 5% SC in celery were carried out in Shanghai and Yinchuan. The ultra-high performance liquid chromatography-tandem mass spectrum (UPLC-MS/MS) was used to determine the residues of these insecticides in celery. Dietary intake risk assessments were performed. Field experiments showed that the final maximal residues of imidacloprid 5% GR, abamectin 0.5% GR and chlorantraniliprole 5% SC in celery collected at safe intervals were 0.97 mg/kg, 0.01 mg/kg, and 5.24 mg/kg respectively, when they were applied at their recommended dosages. All of the final concentrations were below their maximum residue limits in celery. The risk assessments showed that the maximum value of %ADI of imidacloprid, abamectin and chlorantraniliprole was 5.17%, and that of %ARfD was 11.2%, which were far below 100% with a low exposure risk. Therefore, imidacloprid, abamectin and chlorantraniliprole were applicable as alterative insecticides for celery. |
