【摘要】 应用气相色谱-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11个被检出含有AP,最高含量为46 ng/L;沉积物中所有样品均检出AP,含量为61~1 236 ng/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含量自湾顶向湾口递增,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.更多还原

【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 1236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 carbon(TOC) content in the sediments.Furthermore,a remarkable correlation between AP content and TOC content is revealed by means of linear regression analysis.更多还原
