AbstractIn order to investigate the levels and distributions of parabens in the sediments from typical tidal estuarine zones in China, six paraben analogues, methyl-(MeP), ethyl-(EtP), propyl-(PrP), butyl-(BuP), benzyl-(BzP) and heptyl parabens(HepP) were determined by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The results showed that the total concentration (sum of six parabens:∑parabens) of parabens in the sediment samples ranged from 2.20 to 24.5 ng·g-1, with a geometric mean value of 8.11 ng·g-1. That was slightly higher than those reported from the United States (4.93 ng·g-1), Japan (5.78 ng·g-1) and South Korea (6.46 ng·g-1). MeP was the predominant compound among the six paraben analogues (detection rate:100%, percent contribution:79.9%), followed by PrP (91%, 17.7%). Nevertheless, BuP and HepP were not found in any sediment samples. The total concentration of parabens in the sediments from Jiulong Estuary was the highest (geometric mean ∑parabens:14.6 ng·g-1), while that from Beidai River Estuary was the lowest (4.34 ng·g-1). Principal component analysis suggests the similar source of parabens in the sediment samples from tidal estuarine zones in China.
Other Abstract为了解对羟基苯甲酸酯(Parabens)在我国典型河口潮间带沉积物中的含量水平与分布特征,应用HPLC-MS/MS对采自国内典型河口潮间带沉积物样品中6种Parabens污染物(MeP、EtP、PrP、BuP、BzP和HepP)的含量进行测定.测定结果显示,沉积物中Parabens总含量(∑parabens;6种Parabens单体含量总和)介于2.20-24.5 ng·g-1之间,几何平均含量为8.11 ng·g-1,略高于美国(4.93 ng·g-1)、日本(5.78 ng·g-1)和韩国(6.46 ng·g-1)等地所报道的结果.在6种Parabens单体中,MeP为主要的单体(检出率:100%,贡献率:79.9%),其次是PrP (91%,17.7%);而BuP和HepP在所有测定的沉积物样品中均未检出.九龙江潮间带沉积物中∑parabens的含量水平最高,其几何平均含量为14.6 ng·g-1;而北戴河潮间带沉积物中∑parabens的含量水平最低,其几何平均含量为4.34 ng·g-1.主成分分析结果表明各潮间带沉积物样品中Parabens的来源非常相似.
