200 g/L氯虫苯甲酰胺悬浮剂施用于稻田的环境风险评估

Environmental Risk Assessments of 200 g/L Chlorantraniliprole SC Applied to Rice Field

本研究依据中华人民共和国农业行业标准,整体评估了200 g/L氯虫苯甲酰胺悬浮剂(SC)施用于稻田后对环境产生的风险。环境风险评估对象主要包含水生生态系统、鸟类、蜜蜂、家蚕、地下水、非靶标节肢动物和土壤生物。评估中使用的模型为TOP-RICE和PECsoil_SFO_China。评估结果显示,按照良好农业规范(GAP),在稻田中施用200 g/L氯虫苯甲酰胺SC对鸟类、蜜蜂、地下水、非靶标节肢动物和土壤生物风险低,属于可接受风险;对家蚕、水生生态系统风险高,为不可接受风险。因此,我们应避免在家蚕养殖地、桑叶采摘地附近施药,同时应远离水产养殖区,以及禁止在施药后将田水直接排入水体,以免其中的有效成分对环境产生不利影响。

The study integrally assessed the environmental risks caused by the application of 200 g/L chlorantraniliprole SC in rice field according to agricultural industry standards of the People's Republic of China.The objects of environmental risk assessments mainly included aquatic ecosystems,birds,bees,silkworms,groundwater,non-target arthropods and soil organisms.The evaluation models were TOP-RICE and PECsoil_SFO_China.The results showed that 200 g/L chlorantrani-liprole SC posed acceptably low risks to birds,bees,groundwater,non-target arthropods and soil organisms,whereas it posed unacceptably high risks to aquatic ecosystems and silkworms when applied to rice field in accordance with Good Agricultural Practice(GAP).Therefore,we should avoid applying 200 g/L chlorantraniliprole SC near the silkworm breeding base and mulberry leaf picking base.Meanwhile,application of 200 g/L chlorantraniliprole SC should be far away from aquaculture areas,and field water was prohibited to directly discharge into the water bodies after application in order to avoid the potential adverse effects of the active ingredients on the environment.
