【摘要】 对巢湖水相、沉积相和生物相中Pb, Cu, Fe的污染状况进行了分析与评价.结果表明,巢湖水体除少数样点Pb, Cu含量达Ⅲ~Ⅴ类水质标准外,其余水质较清洁;底泥Pb, Cu污染较严重,Fe均为自然背景值不存在污染.从水体生物鱼类的检测结果来看,Pb的累积倍数最大,变幅也大;Cu的累积倍数鱼类为10~40倍,而虾类达300倍以上;Fe的累积倍数较小,均在100倍之内.更多还原

【Abstract】 The pollution state of Pb, Cu and Fe in the water, sediment and organism phases of Chaohu Lake was analyzed and assessed. Judged by the contents of Pb, Cu, Fe, the water quality of Chaohu Lake waters was comparatively clean except the Pb and Cu of a few sample reaching Ⅲ~Ⅴ water quality. The sediment was polluted rather seriously by Pb and Cu. Fe had no pollution and all possessed nature backgroup value in the bottom sediment without the trace of external pollution. From the test result of the bionic fish in water, it showed that the accumulation multiple of Pb was the greatest, and its range was also great. The accumulation multiple of Cu was 10~40 in fish and that in shrimp reached higher than 300 multiples. The accumulation multiple of Fe is smaller, all being lower than 100 multiples.更多还原
