摘要: 应用气相色谱一质谱法研究了伶仃洋水和沉积物中烷基酚(AP)的污染状况.检测12个水样中有l 1个被检出含有AP,最高含量为46ng/L;沉积物中所有样品均检出AP,含量为61~1236ng/g,结果表明,澳门内港AP污染最严重.伶仃洋水体中AP含量有自湾顶向湾口递减的趋势;就沉积物而言,AP含量自湾顸向湾口递增,并在香港附近达到最大值,这与沉积物中总有机碳(TOC)的分布特征相似.相关性分析显示,AP含量与TOC之间显著相关.

Abstract:

The alkylphenol(AP)in the surface water and sediments from Lingding Bay is determined by means of GC-MS method.The results show that 11 water samples out of 12 are polluted by AP,with the highest content up to 46 ng/L,that all the sediment samples contain AP with the content of 61 to 1236 ng/g,and that Macao Harbor is most seriously polluted,the AP content in the surface water in Lingding Bay seaward decreasing while that in the sediments seaward increasing to a maximum near Hong Kong,which is similar to the variation of total organic car-bon(TOC)content in the sediments.Furthermore,a remarkable correlation between AP content and TOC content is revealed by means of linear regression analysis.
