In this study, surface seawater and sediment samples were collected from Bohai Sea, China, to investigate the temporal and spatial distributions of perfluoroalkyl substances (PFASs) in that area. The total concentrations of PFASs in seawater and sediment samples ranged from below method limit of quantification (<MLQ) to 99.4 ng/L, and from 0.33 to 2.78 ng/g dw, respectively. PFOA was the predominant PFASs in both of surface seawater and sediment samples, with a median concentration of 4.97 ng/L in seawater and 0.24 ng/g dw in sediment sampled in July, respectively. Seasonal variation of the total PFAS concentrations was found in seawater samples, but not in the sediments. The concentrations of the total measured PFASs in water samples from drain outlets ranged from 103 ng/L to 443 ng/L, which was four times higher than that in seawater from the Bohai Sea, suggesting that discharge of wastewater from drain outlets was responsible for the contamination of PFASs in Bohai Sea area.
在本研究中，采集了中国渤海的表层海水和沉积物样本，以调查该区域全氟烷基物质（PFASs）的时空分布。海水和沉积物样本中PFASs的总浓度分别在低于方法定量限（<MLQ）至99.4 ng/L以及0.33至2.78 ng/g干重之间。全氟辛酸（PFOA）是表层海水和沉积物样本中主要的PFASs，7月采集的海水样本中PFOA的中位浓度为4.97 ng/L，沉积物中为0.24 ng/g干重。海水样本中发现了总PFAS浓度的季节性变化，但沉积物中未发现。排水口水样中测得的总PFASs浓度在103 ng/L至443 ng/L之间，比渤海海水中的浓度高四倍，这表明排水口排放的废水是渤海地区PFASs污染的原因。
