西瓦湖中壬基酚和双酚A的污染特征

Distribution Characteristics of Nonylphenol and Bisphenol A in Shihwa Lake

本文研究了西瓦湖内外各环境介质 ,包括表层水体、悬浮物、间隙水和沉积物中的壬基酚和双酚 A的浓度分布。结果表明 ,湖内上述介质中的壬基酚浓度分别为 1 7.4～ 1 1 3.4 ng/ L ,1 5 .6～ 2 8.6 ng/ L,2 4 0～ 3890 ng/ L和 5 .6～ 1 6 2 9ng/ g,西瓦湖外的壬基酚浓度则相对较低。表层水体与其他介质中的壬基酚浓度之间存在显著性相关关系。双酚 A的分布特征与壬基酚相似 ,但前者的浓度较低 ,在上述介质中的浓度分别为 1 3.0～ 5 0 .4 ng/ L,3.2～ 8.5 ng/ L,85～ 2 80 ng/ L和 1 .3～1 1 .2 ng/ g。本文还讨论了西瓦湖中的壬基酚和双酚

The distribution patterns of nonylphenol and bisphenol A in surface water, suspended solids, pore water and sediments in Shihwa Lake were studied. Nonylphenol concentrations in these media of Shihwa Lake were in the range of 17.4～113.4ng/L, 15.6～28.6ng/L , 240～3 890ng/L and 5.6～1 629ng/g , respectively. The concentrat ions outside the lake were relatively lower. Nonylphenol in the surface water showed significant correlations with those in other media. Bisphenol A showed a similar distribution pattern with nonylphenol, but its concentrations were much lower, in the range of 13.0～50.4ng/L , 3.2～8.5ng/L , 85～280ng/L and 1.3～11.2ng/g , respectively in the above media. Possible effects of nonylphenol and bisphenol A pollution on various organisms in Shihwa Lake were discussed.
