The extent of contamination of the Black Sea by selected organochlorine compounds has been assessed through the analysis of surficial sediments taken from throughout the region. Concentrations of HCHs at sites influenced by the Danube delta are among the highest recorded on a global basis (up to 40 ng g(-1) dry wt). The ratio between the alpha- and gamma-isomers was relatively low indicating contamination through the use of lindane. Concentrations of DDTs (0.06-72 ng g(-1) dry wt) and PCBs (0.06-72 ng g(-1) dry wt) were not especially high in comparison to levels reported from throughout the world. The DDE/DDT ratio was, however, low indicating fresh inputs and hence current usage of DDT within the Black Sea region.
通过对从整个黑海地区采集的表层沉积物进行分析，评估了选定有机氯化合物对黑海的污染程度。受多瑙河三角洲影响的地区，六氯环己烷（HCHs）的浓度是全球记录中最高的（高达40纳克/克干重）。α-异构体和γ-异构体之间的比例相对较低，表明污染来自林丹的使用。与世界各地报告的水平相比，滴滴涕（DDTs）（0.06 - 72纳克/克干重）和多氯联苯（PCBs）（0.06 - 72纳克/克干重）的浓度并不特别高。然而，DDE/DDT比例较低，表明有新的输入，因此黑海地区目前仍在使用滴滴涕。
