摘　　要：以吡虫啉为代表的新烟碱类杀虫剂具有农业用量大、环境残留高和对非靶标生物毒性效应显著的特征,引发的生态环境问题日益凸显。光解是环境中有机农药的主要降解方式之一。根据近年来的文献报道,简述新烟碱类杀虫剂在环境中残留的潜在生态毒性风险和光降解转化行为,以期为正确评估该类化合物在环境介质中残留的环境健康风险提供科学依据。The neonicotinoids insecticides, represented by imidacloprid, have the characteristics of large agricultural consumption, high environmental residues and significant effects on non-target biological toxicity. The ecological environment problems caused by neonicotinoids have become increasingly prominent. Photolysis is one of the main degradation of organic pesticides in the environment. Based on the literature reports in recent years, the potential ecological toxicity risks and photodegradation of nicotinic insecticides in the environment were briefly described. It provides theoretical guidance for the correct assessment of environmental risks of neonicotinoids residues in environment.
