地下水嘧磺隆污染分析研究

目前国内外学者对嘧磺隆研究主要集中在其防除杂草的效果和用量方面,而对环境产生的生态效应研究仍然是一个空白。本文以某市用地下水灌溉蔬菜后相继出现受害事件展开调查,通过实地勘察农作物及其他野生植物的受害症状和特征,对污染区的潜水进行了全量分析,排除了地下水中无机物污染的可能。通过相关有机物的确认模拟试验,初步认定潜水遭受污染可能与嘧磺隆有关。在检测污染区及非污染区潜水中嘧磺隆含量和分析污染区地貌、水文地质条件的基础上,进行综合分析论证,得出了地下水确系嘧磺隆污染的符合实际情况的结论,为受害区农业生产污染防治提供了依据。

Analyzed research of groundwater pollution by sulfometuron methyl

Sulfometuron methyl that had new, low toxicity and high effect properties and used forest or non-cultivated land was an unselected and broad pedigree herbicide. Scholars at home and abroad focused on researches in weed-control effects of sulfometuron methyl and applied amounts at present. Research on ecological effect was still blank. The affairs that vegetables were damaged with irrigating groundwater at a certain city were set off in this research. The preliminary results were concluded that pollution of groundwater had a relation with sulfometuron methyl by investigating the injured farm crops and other wilding plants and analyzing contents of inorganic and organic matter in groundwater. At the same time the possibility that groundwater was polluted by inorganic matter was ruled out. On the base of simulating experiments of organic matter confirmed, clarifying the geography of pollution area, and explaining hydrogeological conditions, synthetical studies were proceeded and conclusions that groundwater was really polluted by sulfometuron methyl were reached finally. These accorded with the actual situations. Above achievements provided basis for pollution area to prevent contamination in agriculture production.
