Chemical contamination of the coastal marine environment by polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) was assessed along with emerging contaminants such as polybrominated diphenyl ethers (PBDEs) in an industrially well-developed country (France) and a fast-developing country (Korea). Other chemicals, i.e. nonylphenol (NP) and 5 beta(H)-cholestan-3beta-ol (coprostanol) were determined to trace industrial waste and/or domestic inputs. These compounds were analyzed in coastal sediments and mussels in two enclosed coastal water bodies: Masan Bay (South Korea) and Thau lagoon (France). The overall levels of target organic contaminants were higher in Masan Bay than in Thau lagoon. The mean concentrations of 17 PCDD/Fs, 13 PBDEs, NP and coprostanol in Masan Bay sediments were, respectively, 1.3, 11, 248 and 291 ng g(-1) dry weight (d.w.); in Thau lagoon sediments they were, respectively, 0.39, not detectable (nd), 23 and 395 ng g(-1)d.w. Mean concentrations in mussels (coprostanol and cholestanol were not measured) were 0.0093, 13, 140 ng g(-1)d.w. in Masan Bay and 0.016, 0.94, 38 ng g(-1)d.w. in Thau lagoon. Principal component analysis of the contaminants and chemical tracers indicates possible point sources of pollution for Masan Bay and Thau lagoon. This study highlights a growing pollution problem in Asia and in particular a tremendous uptrend in Korea, in comparison to more controlled discharges and releases in Western Europe.
对工业化程度较高的国家（法国）和发展迅速的国家（韩国）的沿海海洋环境中的多氯二苯并对二恶英（PCDDs）和多氯二苯并呋喃（PCDFs）等沿海海洋环境中的化学污染物以及新兴污染物（如多溴二苯醚（PBDEs））进行了评估。其他化学物质，即壬基酚（NP）和 5β（H）-胆甾烷-3β-醇（粪甾醇），被用来追踪工业废物和/或国内投入。这些化合物在两个封闭的沿海水体中，即马山湾（韩国）和索恩泻湖（法国）的沿海沉积物和贻贝中进行了分析。目标有机污染物的总水平在马山湾高于索恩泻湖。马山湾沉积物中 17 种 PCDD/Fs、13 种 PBDEs、NP 和粪甾醇的平均浓度分别为 1.3、11、248 和 291ng/g（干重）（d.w.）；索恩泻湖沉积物中的平均浓度分别为 0.39、未检出（nd）、23 和 395ng/g（d.w.）。贝类（未检测到粪甾醇和胆甾醇）中的平均浓度分别为 0.0093、13、140ng/g（d.w.）在马山湾和 0.016、0.94、38ng/g（d.w.）在索恩泻湖。污染物和化学示踪剂的主成分分析表明，马山湾和索恩泻湖可能存在点污染源。本研究突出了亚洲日益严重的污染问题，特别是与西欧更受控的排放和释放相比，韩国的污染呈巨大上升趋势。
