Six volatile halogenated organic compounds (VHOC), namely, chloroform, carbon tetrachloride, trichloroethylene, bromodichloromethane, dibromochloromethane, and bromoform, were studied in the Yellow Sea and East China Sea from April to May, 2009. The spatial variability of these VHOC was influenced by various factors, including anthropogenic inputs, biogenic production and complicated hydrographic features such as Changjiang Diluted Water, Yellow Sea Cold Water Mass, and Kuroshio Current. Diurnal study results showed that factors such as solar irradiation, biological activity, and tide affected the abundance of these VHOC. Correlation analyses revealed that bromodichloromethane was positively correlated with chlorophyll a in surface seawater. Principal component analysis suggested that chlorinated compounds like carbon tetrachloride originated from anthropogenic sources whereas brominated compounds such as bromodichloromethane originated from biogenic sources. Sources of other chlorinated and brominated compounds may not be governed by biological processes in the marine environment.
2009年4月至5月,对黄海和东海中的六种挥发性卤代有机化合物(VHOC),即氯仿、四氯化碳、三氯乙烯、二溴一氯甲烷、一溴二氯甲烷和溴仿进行了研究。这些VHOC的空间变异性受多种因素影响,包括人为输入、生物源生产以及长江冲淡水、黄海冷水团和黑潮等复杂的水文特征。昼夜研究结果表明,太阳辐射、生物活性和潮汐等因素影响了这些VHOC的丰度。相关性分析显示,表层海水中的二溴一氯甲烷与叶绿素a呈正相关。主成分分析表明,像四氯化碳这样的氯化化合物源自人为源,而像二溴一氯甲烷这样的溴化化合物源自生物源。其他氯化和溴化化合物的来源可能不受海洋环境中生物过程的控制。
