As元素及其化合物进入人体血液循环后直接作用于毛细血管壁,使其通透性增强,麻痹毛细血管,造成组织营养障碍,产生急性和慢性中毒。通过测定比拉都地区水系沉积物中As元素含量,运用地质累积指数法和平面等值线法,在该区域圈出三个污染区,并对三个污染区的污染程度进行等级划分。Ⅰ号污染区总共四个污染级别,从轻度污染-偏重度污染;Ⅱ号污染区总共四个污染级别,从轻度污染-偏重度污染;Ⅲ污染区总共三个污染级别,从轻度污染-中度污染。三个污染区的污染源都在最高污染级别所圈定的区域内。
As元素及其化閤物進入人體血液循環後直接作用于毛細血管壁,使其通透性增彊,痳痺毛細血管,造成組織營養障礙,產生急性和慢性中毒。通過測定比拉都地區水繫沉積物中As元素含量,運用地質纍積指數法和平麵等值線法,在該區域圈齣三箇汙染區,併對三箇汙染區的汙染程度進行等級劃分。Ⅰ號汙染區總共四箇汙染級彆,從輕度汙染-偏重度汙染;Ⅱ號汙染區總共四箇汙染級彆,從輕度汙染-偏重度汙染;Ⅲ汙染區總共三箇汙染級彆,從輕度汙染-中度汙染。三箇汙染區的汙染源都在最高汙染級彆所圈定的區域內。

As and its compounds will have a direct effect on the capillary wall after they enter into the blood circulation , which makes the permeability enhancement , paralysis capillaries , results in organization dystrophy , produces acute and chronic poisoning . By measuring the content of As in sediments of bela , we circled three contaminated areas in the region , and contamination levels were graded with geological accumulation index method and planar isoline method . There are four contamination levels from light pollution to emphasis pollution in No .Ⅰcontaminated areas and No .Ⅱcontaminated areas and three contamination levels from light pollution to middle pollution in No .Ⅲcontaminated areas .The contaminated sources of three contaminated areas are in the area delineated according the highest contamination levels .
