三门湾蛇蟠海域环境质量现状评价

根据 1 997年 8月三门湾蛇蟠海域现场调查结果 ,采用环境质量指数法 ,对该海域的环境质量现状进行了初步的分析与评价。结果表明 ,该海域除营养盐及锌含量超标外 ,其它环境要素基本符合一类海水水质标准及底质标准。水体中营养盐含量普遍偏高 ,无机氮含量 98%超一类海水水质标准 ;活性磷酸盐 66%超一类海水水质标准。沿岸锌矿的开采在一定程度上影响了该海域重金属中的锌含量

Assessment on present environmental quality of Shepan in Sanmen Bay

The results show that the present environmental quality in this sea area is quite well. Except for some nutrient elements and Zn, all other environment chemical elements meet the standard of first grade water quality or sediment. The content of nutrient elements in this sea area is quite high. 98% inorganic nitrogen value exceeds the first grade standard, so does inorganic phosphorus value which is 66%.
