Оценка экологического риска на основе анализа критических нагрузок на экосистему регионального хранилища радиоактивных отходов
2012
Developed method for assessing environmental risk based on the analysis of critical loads on the natural ecosystems exposed to anthropogenic impact is presented in the article. The developed approach consists of five stages. The first stage is to determine the impact indicators and assess their magnitudes. The second stage is to identify reference species and the reference indices. The third stage is to identify and analyze critical loads based on assessment of "dose-response" relationship. The fourth step is to estimate an environmental risk associated with critical loads. The fifth stage is to compare the obtained estimates with acceptable risk values. On the basis of risk data the state of the study area should be recognized as unsatisfactory – the risk exceeds the acceptable level by 43 % and 56 % depending on the critical characteristics.
