Comparative analysis of methods for assessing oily solid waste environmental hazard

The article is devoted to an actual problem of applied ecology - reliable determination of hazard class of oily solid waste, formation of which is significant and contributes greatly to the overall level of negative impact on the environment of oil producing and oil refining enterprises. Comparison of determination of an oily solid waste chemical composition with the results of hazard classes determination by computational and experimental methods has revealed a number of fundamental problems. Their solution requires changing scientific and methodological approaches to methods of determining environmental hazard (class of hazard) and biological activity of oily solid waste. In particular, in quantitative chemical analysis of waste it is not appropriate to determine the content of heavy metals. In biological experiments, a comprehensive approach using a wider range of test objects is necessary.
