Abstract

The monitoring results of organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) in Ukranian and world surface river waters were summarized. Total concentrations of OCPs, PCBs and PAHs in surface waters of Ukrainian rivers (Dnieper and Dniester) were 1.4–17.1; 2.8–57.2; 7.5–378.6 ng/dm3 , respectively. These pollution levels are medium on a global scale. Higher concentrations were recorded in the surface water of China, India and other Asian countries. Distribution of these organic ecotoxicants between water and suspended particulate matter (dispersionphase distribution) was analyzed and it was shown that in the majority of river waters ≥50% of them are associated with suspended particles. By the case of River Dnieper antibate correlations between watersoluble parts of individual OCPs, PCBs and PAHs and coefficient of their hydrophobicity were recorded. These correlations were presented graphically. In addition, relevant correlation coefficients and criterions of probability were calculated. The clearest correlation was established for PCBs.

地表水和悬浮颗粒物中有机氯农药、多氯联苯和多环芳烃的监测与分布

综述了乌克兰和世界各国地表水中有机氯农药(OCPs)、多氯联苯(PCBs)和多环芳烃(PAHs)的监测结果。乌克兰河流(第聂伯河和德涅斯特河)地表水中OCPs、多氯联苯和多环芳烃总浓度为1.4 ~ 17.1;2.8 - -57.2;7.5-378.6 ng/dm3。这些污染水平在全球范围内属于中等水平。在中国、印度和其他亚洲国家的地表水中记录到较高的浓度。分析了这些有机生态毒物在水体和悬浮颗粒物之间的分布(分散相分布)，结果表明，在大多数河流水体中，有机生态毒物中有50%以上与悬浮颗粒物有关。以第聂伯河为例，记录了各有机磷化合物、多氯联苯和多环芳烃水溶性组分之间的相关性及其疏水性系数。这些相关性用图形表示出来。并计算了相关的相关系数和概率判据。多氯联苯的相关性最明显。
