摘要
2017—2019年从成都市20个区县的基地采集531份蔬菜样品,采用GB 23200.19—2016、GB/T5009.144—2003、SN/T 3643—2013、NY/T 761—2008等方法对样品进行66种农药的残留检测,检测结果依据GB 2763—2016进行判定。结果表明,在所有样品中,92份蔬菜样品检出共计32种农药残留,农药检出率达17.33%。其中1份样品超标、9份样品检出蔬菜禁用农药毒死蜱和氟虫腈,不合格率达1.88%。叶菜类蔬菜占检出样品的39.13%,叶菜类蔬菜检出7份样品不合格,占总不合格率的70.00%。蔬菜中农药使用普遍,叶菜类蔬菜农药残留尤为突出,应加强农药质量管理、强化标准化生产管理、完善农药残留限量标准、加大禁限用农药的查处力度、加大基地和市场的检测频率,减少农药残留对人体和环境的影响。
