arsenic group

Both arsenic ( As) and Sb belong to the same main group, and they are usually associated exist to form a As-Sb combined pollution.

砷与锑属于同一主族且经常伴生存在，因此经常会形成砷锑复合污染。

Selenium at dose of 100 μ g/ kg · bw can weaken some toxic effects of arsenic, such as decrease of erythrocyte count, hemoglobin contents and total concentration of hydrosulfide group in blood, spleen swelling, pathological damages to the liver, kidney and lung.

当硒剂量达100μg/kg·bw时，对砷中毒导致的红细胞数下降、血红蛋白含量降低、血液巯基总量下降、脾肿大、肺、肝、肾等组织的病理学改变具有一定的保护作用。

Samples were treated and detected with alkali-ash method and iodine content in Nang before and after baking of every group with arsenic-cerium oxidation reduction method, respectively. Statistics was taken to analyze the loss of iodine in Nangs of every section.

用碱示灰化法测定处理样品，砷-铈氧化还原法分别测定各组馕烤制前后碘元素含量，用卫生统计学分析各组馕中碘元素损失情况，对碘盐加工烤馕中碘含量损失的进行研究。

results: after intervention, compared with exposed arsenic control group: sod activities in the liver increased while the mda contents in the same tissue decreased in vitamin c group, vitamin e group and dimercaptopropanol group ( p < 0.05).
