重庆市基地蔬菜农药残留污染现状及控制对策

Pesticide Residues in Vegetables from Chongqing and Suggested Control Strategy

为了摸清重庆市蔬菜农药污染现状,2004—2005年分别对重庆市51个主要蔬菜基地和主城区流通市场中蔬菜产品中农药残留进行了调查监测。结果表明,51个蔬菜基地有29个基地未检出禁用农药,占总数的56.8%;基地蔬菜中主要农药残留污染为甲胺磷、氧化乐果、水胺硫磷、对硫磷和克百威;叶菜类农药残留超标率最高,根茎类次之,瓜果类再次之,豆类最低。据此提出的对策主要有:对无公害蔬菜生产应加强领导,优化无公害蔬菜基地布局,树立"积极发展远郊,适度发展近郊,保护治理城郊"的战略思想;加强无公害蔬菜基地的管理和监督,强化无公害蔬菜监测体系的建立和产品质量安全监督检测;完善重庆市的蔬菜质量安全检测体系建设,建立市、区(县)、基地三级监测体系,努力实现蔬菜质量安全的全覆盖监测;建立蔬菜质量安全预警机制,确保蔬菜的质量安全。

Pesticide residues in vegetables have been receiving a great attention by relevant government departments in Chongqing, a metropolis in China with large industry and agriculture. In order to clarify current state of pesticide pollution in Chongqing, fifty-one vegetables have been collected and monitored. In addition, some research and evaluation on pollution characteristics of pesticide residues were carried out. The results showed that： illegal pesticides were not detected in twenty - nine vegetables, accounting for 56.8% of the total fifty - one bases in Chongqing in 2005, while it was not detected in seven districts （municipalities）, accounting for 33.3% of the total 21 districts.
