中文摘要：

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．

英文摘要：

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 carbon （TOC） content in the sediments. Furthermore, a remarkable correlation between AP content and TOC content is revealed by means of linear regression analysis.
