The Ecological Assessment of Petroleum Industry Wastes

摘要

The ecological assessment of waste is an important indicator of industrial enterprise operations. The article discusses the results of research (type of environment, salt content, heavy metal and petroleum product content), encompassing ten types of different petroleum industry waste. During the research the radioactivity levels of samples were determined, and the biotesting was carried out. The main focus was on the influence of the water extract from waste on living organisms. The biotesting was carried out on water fleas, ciliates, aquarium fish and high flora seeds. Besides, the ecological characteristics of waste were studied with help of microorganisms. Based on the complex analysis of samples it was determined that the studied waste types belong to either the IV or V hazard classes (low hazard) according to national norms. As a result of the research possible methods of waste recycling were offered.
