摘要
对珠江三角洲河流表层沉积物中的壬基酚(NP)进行了分析.结果表明,NP在所有样品中均有检出,其含量范围在110～7808ng/g之间. 其中,珠江广州河段污染水平最高,狮子洋水道明显低于上游珠江广州河段,东江位居其后,西江最低.沉积物中总有机碳(TOC)的分布特征与NP相似,相关分析显示TOC与NP之间显著性相关.
Nonylphenol （NP） in surface sediments from rivers of the Pearl River Delta was analyzed. All the sediment samples were measurable with NP concentration in the range of 110-7808ng/g. The Guangzhou Channel was the highest and there was obviously an decrease in going from the Guangzhou Channel to the Shiziyang River. The Dongjiang River followed the Shiziyang River and the Xijiang River was the lowest. The total organic carbon （TOC） distribution trend in the sediment was similar to NP. The correlation analyses showed the remarkable correlation between TOC and NP.
