摘要

目的。测定沃林地区卡明-卡什尔斯基、柳别什夫斯基和马内维奇行政区居住区范围内水体中放射性核素137Сs、90Sr和重金属的含量。在考察和实验室工作中,根据现行的放射化学、放射光谱学、鱼类学、水化学、统计分析等方法,采用了标准的取样、制备和测量方法。采用常规方法在实验室条件下测定重金属总含量。结果。本研究基于自身的分析,以及水管理与生态监测与优化用水科学信息中心的库存资料。考虑了Volyn地区放射性污染带内水库(水、沉积物、鱼、鸟)中137Сs、90Sr核素的分布特征。测定了研究区内137Сs、90Sr的最大浓度。查明了部分受污染地区某些水体生态系统环节中有毒物质的人为影响和超过最大允许浓度和最大允许水平。结论。通过对调查地区(居民点范围内)水中137Сs和90Sr及重金属浓度水平的研究,发现Prylisne村、Velyka Osnytsya村、Manevitsky区的Cherevakha村、Kamin-Kashirsky区的Nuyno村和Lyubeshiv行政区的Vetly村的水库受到137Сs和90Sr浓度最高的影响。在水库中记录了重金属盐的显著含量,即在Serhiv村-铅,在Manevytskyi区Prylisne村-锌,镉;柳别斯希夫区的别列兹纳·沃利亚村-铜;在卡明-卡什尔斯基地区的努伊诺村。

Radiological Assessment of Reservoirs in Volyn Region that is Under Radioactive Contamination
Purpose. To determine the content of radionuclides 137Сs, 90Sr and heavy metals in water bodies within the boundaries of settlements of Kamyn-Kashirsky, Lyubeshivsky and Manevychi administrative districts of Volyn region. Methods. During the expedition and laboratory work, standard methods of sampling, preparation and measurement of samples were used according to the current methods of radiochemical, radiospectrometric, ichthyological, hydrochemical, statistical analyses, etc. The determination of the total content of heavy metals was performed in laboratory conditions by conventional methods. Results. The research is based on its own analyses, as well as the stock materials of the Scientific Information Center for Water Management and Ecological Monitoring and Optimization of Water Use. Features of 137Сs, 90Sr radionuclides distribution in reservoirs (water, sediments, fish, birds) within the zone of radioactive contamination in Volyn Region are considered. The maximum concentrationі of 137Сs, 90Sr in the studied area were determined. The anthropogenic impact and excess of the maximum permissible concentrations and maximum permissible levels of toxic substances in the ecosystem links of certain water bodies of the partially contaminated region are identified. Conclusions. As a result of the study on the level of concentrations of 137Сs and 90Sr and heavy metals in water (within the boundaries of settlements) of the investigated area, it was found that reservoirs in village of Prylisne, village of Velyka Osnytsya, village of Cherevakha in Manevitsky District, village of Nuyno in Kamin-Kashirsky District and the village of Vetly in Lyubeshiv Administrative Distict are affected by the highest concentrations of 137Сs and 90Sr. The significant content of heavy metal salts is recorded in the reservoirs, namely in the village of Serhiv – lead, village of Prylisne in Manevytskyi District– zinc, cadmium; in the village Berezna Volia in Lyubeshiv District – copper; in the village of Nuyno in Kamin-Kashirsky District – lead.
