The paper deals with the examination of samples of sewage sludge mixed with charcoal. The aqueous extracts were prepared from the experimental samples of the sewage sludge mixing with charcoal. The extracts were monitored by the selective physicochemical parameters. The ecotoxicological properties of charcoal with the addition of sewage sludge were evaluated based on the ecotoxicological tests performed in this experiment. Our investigation obtained results and it is considered to improve the properties of sewage sludge in its future recovery and minimize the negative impacts on the environment, which are to a large extent, sewage sludge unsuitable for further use.

Keywords: sewage sludge, charcoal, nutrients, ecotoxicological tests
