Semi-permeable membrane devices (SPMDs) were applied to sample some Organochlorinated Pesticides (OCPs), Polycyclic Aromatic Hydrocarbons (PAHs) and Polychlorinated Biphenyls (PCBs) from the seawater of 14 Chinese coastal areas. The total concentrations of OCPs (∑OCPs), PAHs (∑PAHs) and PCBs (∑PCBs) were in the ranges of 489.2-2174, 589.4-53,160, and 133.2-3658 ng/g lipid, respectively. The ∑PAHs varied significantly with the sampling locations, which were far higher in north Chinese coastal areas than in south areas, whereas ∑OCPs and ∑PCBs only slightly fluctuated along the entire coast line. Comparing SPMD to grab sampler, it was found that the distribution patterns of the PCBs and OCPs in seawater were generally similar. However, the compositional profiles of the PAHs, PCBs, DDTs and HCHs in SPMDs were slightly different to grab samplers and organisms. The SPMDs accumulated less lipotropic compounds, which are inclined to dissolve in water rather than in organisms.
采用半透膜装置(SPMDs)对中国 14 个沿海地区海水中的一些有机氯农药(OCPs)、多环芳烃(PAHs)和多氯联苯(PCBs)进行了采样。OCPs(∑OCPs)、PAHs(∑PAHs)和 PCBs(∑PCBs)的总浓度分别在 489.2-2174、589.4-53160 和 133.2-3658ng/g 脂质范围内。∑PAHs 的分布随采样地点有显著差异,中国北方沿海地区的浓度明显高于南方地区,而∑OCPs 和∑PCBs 仅沿整个海岸线略有波动。与抓斗式采样器相比,发现海水中 PCBs 和 OCPs 的分布模式基本相似。然而,SPMDs 中 PAHs、PCBs、DDTs 和 HCHs 的组成谱与抓斗式采样器和生物体略有不同。SPMDs 积累的亲脂性化合物较少,这些化合物更倾向于溶解在水中而不是生物体内。
