呼伦贝尔草原优良牧草及土壤中有机氯农药残留量调查研究

THE DETERMINED AND STUDIED THE ORGANIC CHLORID PESTICIDES RESIDUES IN THE FINE HERBAGE AND SOIL OF HULUNBUIE GRASS LAND

本文根据内蒙古地区草原牧草及土壤中有害物质现状调查技术规范，对著名的畜牧业基地──呼伦贝尔草原优良牧草及土壤中有机氯农药（六六六、ＤＤＴ）残留量进行了调查研究。结果表明，这两种有机氯农药在呼伦贝尔草原牧草及土壤中的残留量低于内蒙古地区的平均水平，更低于国家粮食作物及土壤卫生标准。但其化学性质稳定、脂溶性强，应停止使用。

In accordance with the technical standard for status quo investigation of harmful substances existed in the herbage and soil of lnner Mongolia steppe, we have determined and studiedt he organic ciloridepesticides(BHC, DDT) residues in the fine herbage and soil of Hulunbuir grassland-the famous livesockhusbandry base. The results show that the nsidues of BHC, DDT in the herbage and soil of Hulunbeirgrassland are below the average level of that in the area of lnner Mongolia, and much lower than the statesanitary standard for cereal crops and soil. But for it's stable chemical property and high grease meltability,the use of BHC DDT should be suspended.
