为了了解氯酚(CPS)和溴酚(M)的分布和形成，我们分析了从韩国核电厂(NPP)附近的河流地区和海洋环境中采集的水样和沉积物样品。在海水中只检出苯并酚(2，4-二溴苯酚和2，4，6-三溴苯酚)，而在河水中检测到对氯苯酚、2，6-二氯苯酚、2，4，6-三氯苯酚和2，4，6-三溴苯酚。核电站附近海域检测到2，4-DBP(0.531~32.7 ng/L)，大部分海水中含有2，4，6-TBP(0.378~20.2 ng/L)。在江水中，工业园区附近的样品总浓度较高(0.510~7.64 ng/L)，工业园区附近的样品总浓度较高(118 ng/L)。在海洋沉积物中，苯并酚(99.0-553 ng/g干重)的含量高于环磷酰胺(0.145-16.1 ng/g干重)。河流沉积物中的苯系物含量(1.01-8.55 ng/g干重)远低于海洋沉积物中的含量(10-500倍)。海洋环境和河流环境中苯系物的分布模式不同，除人为来源外，由于自然形成，海洋环境中苯系物的水平相对较高。NPP的氯化过程似乎也形成了bps(2-溴苯酚、2，4-二溴苯酚和2，4，6-三溴苯酚)。然而，污水对核电站附近(约2公里)的海水产生了影响。在河流环境中，CPS占优势，与工业复合体有关。因此，海洋和河流环境中的CPS和BPS是通过各种途径产生的，如人为形成和生物合成。(C)2009爱思唯尔有限公司。保留所有权利。
To understand the distribution and formation of chlorophenols (CPs) and bromophenols (M), we analyzed water and sediment samples collected from the riverine areas and the marine environments near a nuclear power plant (NPP) in Korea. In the seawater, only BPs (2,4-dibromophenol and 2,4,6-tribromophenol) were detected, while CPs and BPs (4-chlorophenol, 2,6-dichlorophenol, 2,4,6-trichlorophenol and 2,4,6-tribromophenol) were detected in the riverine water. 2,4-DBP (0.531-32.7 ng/L) in the seawater was detected in sites near the NPP and 2,4,6-TBP (0.378-20.2 ng/L) was found in most of the seawater. In the riverine water, the sample near the industrial complex (118 ng/L) showed a greater total concentration than others (0.510-7.64 ng/L). In the marine sediments, BPs (99.0-553 ng/g dry weight) showed higher concentrations than CPs (0.145-16.1 ng/g dry weight). The BPs levels (1.01-8.55 ng/g dry weight) in the riverine sediments were much lower (10-500 times) than those in the marine sediments. The distribution patterns of Us and BPs between the marine and riverine environments differed, with relatively high levels of BPs appearing in the marine environments due to natural formation except for anthropogenic sources. The chlorination process of the NPP also seems to form BPs (2-bromophenol, 2,4-dibromophenol and 2,4,6-tribromophenol). However, the effluents had an influence on the seawater near the NPP (about 2 km). In the riverine environments, CPs; were dominant, which are related to the industrial complex. Thus, CPs and BPs in the marine and riverine environments are generated via various routes such as anthropogenic formation and biosynthesis. (C) 2009 Elsevier Ltd. All rights reserved.
