At the first time for the period after the Chernobyl NPP accident the nature of the redistribution of the Sr concentrations in components of the ecosystems of the salt lakes of the Crimea were identified and described. Concentration of Sr in water of the salt lakes depends on the sources of the inflow this radionuclide into aquatic ecosystems and salinity level of lakes water. Until April 2014 the flow of the Dnieper river water through the Northern-Crimean canal was more important factor of contamination of salt lakes of the Crimea by Sr, than atmospheric fallout of this radionuclide after the Chernobyl NPP accident. Concentrations of Sr in water of the salt lakes of the Crimea exceeded 2.4-156.5 times its concentrations in their bottom sediments. The Sr dose commitments to hydrophytes, which were sampled from the salt lakes of the Crimea have not reached values which could impact them during entire the after-accident period.
在切尔诺贝利核电站事故后的这段时期，首次对克里米亚盐湖生态系统各组成部分中锶浓度的重新分布性质进行了识别和描述。盐湖水中锶的浓度取决于该放射性核素进入水生生态系统的流入源以及湖水的盐度水平。直到2014年4月，第聂伯河水流经北克里米亚运河，这一因素对克里米亚盐湖受锶污染的影响比切尔诺贝利核电站事故后该放射性核素的大气沉降更为重要。克里米亚盐湖水中锶的浓度超过其底部沉积物中锶浓度的2.4至156.5倍。从克里米亚盐湖采集的水生植物所接受的锶剂量承诺在事故后的整个时期内尚未达到会对其产生影响的值。
