摘 要:目的 了解海南省境内分布的六大江河水质卫生状况及受污染情况。 方法 采用环境流行病学抽样调查的方法 ,分别对六大江河流域的基本卫生状况进行卫生学调查 ,并分枯、丰水期对各江河流域各断面水质进行 2 9项指标的检测。 结果 ①除南渡江上游外 ,各江河流域上、中、下游均有污染物排放 ,尤以昌化江流域排放量最大 ;②经对六条江河枯、丰水期上、中、下游 3 2个断面 2 9项指标共 2 95 8个数据采样检验分析 ,发现水质感官指标、细菌学指标和铁普遍超标 ,pH值、挥发酚、耗氧量、溶解性总固体、硫酸盐和锰在不同江河段面存在不同程度超标 ,氟化物和汞在南渡江、万泉河和昌化江有不同程度的超标 ,尤其是汞在万泉河中游及昌化江下游严重超标 ,最大超标倍数分别为 2 4倍和 6 9倍。 结论 六大江河污染严重 。Objective To understand the hygienic conditions and polluting status of six rivers in Hainan Province. Methods The general hygienic conditions of the six big rivers and the inspection of 29 indicators concerning the water quality at short and abundant periods were investigated by using environmental epidemiological sampling methods. Results ①pollutants were drained into the upper,middle and lower reaches of 5 of the six rivers excluded Nandujiang River,with Changhuajiang River being the most heavily polluted;②The indicators inspected by sensory organs,microbiological index and iron content solids,sulfate and manganese exceeded the standards at various extents in different parts of the rivers.The contents of fluoride,mercury in the rivers of Nandujiang,Wanquanhe and changhuajiang exceeded the standards at various extents,especially the mercury pollution in the middle reaches of Wanquanhe River and the lower reaches of Changhuajiang River was heavy,2.4 and 6.9 times higher than the hygienic standard. Conclusion The 6 rivers are polluted at various extent and effective measures be taken to improve the water quality.
