摘要

Short chain chlorinated paraffins (SCCPs) have attracted increasing attention due to their potential risks to the ecosystem and human health. However, there is still a lack of systematic research on their environmental fate in the coastal marine environment. In this study, we collected paired seawater (n = 40) and surface sediment samples (n = 40) from East China Sea, and investigated their spatial distribution, partitioning behaviors and ecological risks. The total SCCP concentrations (∑SCCPs) in seawater and sediment samples were in the range of 12.2-430 ng/L and 89.6-351 ng/g (dry weight), respectively. C10-11 SCCPs and Cl5-7 SCCPs were the predominant homologues in all of the samples. This study first calculated the field-based logKOC values for ∑SCCPs in the marine environment, which ranged from 5.0 to 6.5 (mean 5.5). The logKOC values of SCCP homologues (range 3.6-8.0, mean 5.6) showed a weak correlation with their logKOW (R = 0.214, p < 0.05). A preliminary risk assessment indicated that SCCPs at current levels posed no significant ecological risk. Overall, this study contributes to the further understanding of environmental behaviors of SCCPs in the marine environment.
