阿特拉津生态风险及其检测和修复技术研究进展

Advances of studies on ecological risk of herbicide atrazine and its determination and remediation.

随着农药等化学品在农业生产上的广泛应用 ,它们所带来的生态与环境问题日益严重 .在世界许多国家及地区的地表水和地下水中以及大气沉降物中检测出了阿特拉津的残留物 ,它对生态环境的影响具有全球性 .阿特拉津在土壤中的持留期较长并具有生物蓄积性 ,对粮食和食品安全构成潜在威胁 .动物试验结果表明 ,阿特拉津具有生物活性 ,因此深入研究阿特拉津的生态风险问题是当务之急 .文中提出了有关阿特拉津生态风险研究的一些观点 .随着各种检测分析手段的发展 ,阿特拉津的检测技术日臻成熟 ,为研究阿特拉津生态风险创造了有利条件 .

With wide application of chemical such as pesticide in farming, the coming problems of ecological risks and environmental pollution were increasingly serious. Residual material of atrazine was founded in the surface water, underground water, and atmospheric sedimentation, and it resulted in the global ecological influences. For atrazine could exit in soil for a long time and enrich in organism, it would bring about potential threaten on the safety of food. The results from experiments on animal indicated that atrazine had biological activity. So, there is an increasing demand for further studying on its ecological risks. In this paper, some viewpoints of the researches on atrazine were introduced. With the development of analytical techniques, the opportunities were created to study on the ecological risks of atrazine, and people should attach serious importance to the bioremediation techniques.
