Evaluation of Waste Water Pollution

Noxiousness of waste water is directly proportional to the level of its pollution. Different methods for the evaluation of waste water pollution are used throughout the world, the most common being the experimental evaluation method. The method of establishing the charge of pollution or harmfulness of waste water differs from one country to another depending on economic and political factors. This paper provides an overview of the evaluation of waste water pollution in individual Yugoslav republics and autonomous regions. Due to fundamental differences in methodology, the regulations do not assure an equivalent assessment of polluters throughout the country. Based on our experimental work and experience from other authors, a methodology for the evaluation of waste water pollution for Slovenia is suggested.
