Abstract
Introduction. Different conditions of origin of ash and slag wastes has a significant impact on their final properties. Material and methods. The work is devoted to the search and establishment of dependencies of the influence of the origin of ash and slag waste on their chemical and biological parameters by a comprehensive assessment of the results of the impact of ash and slag waste on the vital signs of hydrobionts. Results. The values of the responses of hydrobionts for ash and slag wastes formed from coals of various origins were investigated. The component composition of aqueous extracts from the studied ash slag samples was evaluated. The dependences of the influence of the conditions of origin of ash and slag wastes on their final chemical and biological properties were established. Limitations. An assessment of the biological and chemical properties of ash and slag waste generated during the combustion of coal from six different deposits was carried out. The total volume was 95 samples. Conclusion. Ash and slag wastes formed from the burning of brown coals have the most pronounced toxic effect on hydrobionts, unlike ash and slag from coal.
