Abstract

Monitoring of wastewaters is crucial for the protection of surface waters and should contain quality and toxicity analyses to ensure safety of aquatic organisms. In this study, the impacts of industrial and municipal wastewaters were assessed by examining the responses of organisms from different trophic levels, Pseudokirchneriella subcapitata (microalgae) and Daphnia magna (crustaceans), together with physical and chemical water parameters and total metal(loid) concentrations, separately in wastewater lagoons and four nearby sites in the karst Krka River in spring, summer and autumn. The sites in close proximity to the inappropriately treated wastewaters exhibited diminished ecological status, especially regarding COD, nutrients, turbidity, mineral oils, and elevated concentrations of metals (Cd, Co, Cu, Fe, Na, Ni, and Zn). Toxicity effects were confirmed for surface river water near the municipal wastewater outlet (hazard class III) and for basins with industrial wastewater (hazard class IV). Although such approach enabled determination of the toxic hazard of complex mixtures in aquatic environments, literature overview by CiteSpace showed that data in this field are limited and that European countries dominate in this area of research. In addition, multivariate statistical analysis confirmed association of water quality data and toxic effects and the importance of microbiotests in assessment of ecologically relevant risks for aquatic organisms.
