Report on the Safety Risk of Chlorpyrifos in Rice in Cixi County

  • Online:2015-03-20 Published:2015-03-20

摘要: 利用气相色谱和田间试验,分析研究了毒死蜱在稻谷上的安全使用技术。结果表明,毒死蜱在稻谷中的降解呈现前期快、后期慢的特性,半衰期为8.0 d。不同浓度、不同施药时间稻谷中毒死蜱残留结果表明,毒死蜱在稻谷中的残留期超过45 d,且采收前30 d内使用农药均会产生稻谷中毒死蜱含量超标的风险。

Abstract:  It was an analysis report of the safe use of Chlorpyrifos in rice by gas chromatography and field test. The results showed that the degradation of Chlorpyrifos in rice showed characteristics of early faster , late slower and the half-life of 8.0 d. The study of different concentrations and different time of applying chlorpyrifos showed that the residual period of Chlorpyrifos in rice was more than 45 days, within 30 days before harvest, the use of chlorpyrifos can cause the risk of exceed the standard.

Key words: chlorpyrifos, rice, risk, degration dynamics
