| 摘 要： | 对黄石地区各类水体中砷元素的地球化学特征及污染调查研究表明:1)区域各类水体砷的背景值含量范围为0.52~5.46μg/L,这一值代表了研究区各类水体富砷的化学组成特征.2)区域地质是制约区域水体背景值的主导因素.碎屑岩区水体中As的含量相对较高,pH为中-酸性(6.54~7.14),电导率也很高(R:600~1860μΩ-1).3)区域水环境污染有两类,一类自然污染源是中生代中酸性岩体与与碳酸盐岩接触带夕卡岩型矿体矿化裂隙水及流经二叠系梁山煤组(P1l)和龙潭组(P2l)煤系溪水;另一类是人为污染源,它们是选矿厂、化工厂、有色金属冶炼厂等工业废水.4)各类水体中砷元素的含量、元素组合及pH、Ec等特征明显不同.

| Abstract: | By systematic analysis of each type of water bodies and water pollution in the intermountain basin in Huangshi,where copper deposits are concentrated,we obtain the results as follows.1)The content of As in each type of water bodies is fluctuated between 0.52 and 5.46 μ g/L,which represents the characteristics that the Cu rich region is with high As background water bodies.2)The regional geological setting is the chief factor affecting the background value of As in each type of water bodies,among which the water bodies in the clasolite areas contain relatively higher As,with acidic to neutral pH value (6.15- 7.14) and high electrical conductivity (R:600- 1860 μ Ω - 1).3)The water pollution in the region includes natural pollution and artificial pollution.The former is in the water from the skarn orebody(mineralization)in the contact zone between the Mesozoic acid intermediate rock body and carbonatite and the coal measures of Permian Liangshan group and Longtan group;while the latter is the waste water from dressing plants,chemical plants and nonferrous metal smelteries.4)The different pollution sources vary in the total As contents,the element assemblages,and the physical and chemical characteristics(pH,Ec ets.). |
