气相色谱法测定云和雪梨农药残留量

Determination of Pesticide Residues in Yunhe Pear by Gas Chromatography

采用气相色谱法对云和境内雪梨主要生产基地进行了雪梨农药残留抽样检测。结果显示,参试20份样品中,仅有1份检出百菌清,含量为0.2μg/kg,远低于最大残留量,可见云和雪梨农药残留较低。

The pesticide residues in Yunhe pear were sampled and detected by gas chromatography from the main production bases in Yunhe County.The results showed that only one of the 20 samples detected chlorothalonil(0.2μg/kg),which was much lower than the maximum residue.It could be seen that pesticide residues in Yunhe pear were low.
