dcterms:description
Article is oriented on the cause of sludge ecotoxicity. The ecotoxicity was studied on Daphnia magna and algae Desmodesmus subspicatus. For decreasing of water extract ecotoxicity to the limit value required by Decree No.294/2005 Coll. the addition of different sorbent (active carbon and Amberlite - XAD nonionic polymeric absorbent) were observed. The behaviour of Desmodesmus subspicatus is influenced by turbidity of water extract after adding of active carbon, concentration of nutrients releasing from sludge and also by presence of pollutants (PAHs, AOXs and heavy metals). The addion of activated carbon decrease the concentration of PAHs below the limit which is hazardous for Daphnia magna, but the decreasing of hazardous elements in water extract was not sufficient. The limit value EC50 published in literature for Pb, Zn and Cu was not reached. Article is oriented on the cause of sludge ecotoxicity.
