ECORIVER - Ecotoxicological evaluation of municipal and industrial waste waters
The projects main objective was to demonstrate the importance of eco-toxicology for wastewater management and to establish planning and controlling techniques for industrial and municipal wastewater networks. The project was implemented in the river TrancÃ£o and adjacent basin (a small, but is located in a heavily industrialised and densely populated area and flows into the Tagus estuary). The project integrated an eco-toxicological and psychochemical study of wastewaters from industries in different sectors, wastewater treatment plants as well as receiving waters. Some main conclusions and recommendations are: (1) DTA methodologies are available and should be used in evaluating and controlling wastewater eco-toxicity; (2) following eco-toxicological studies, the use of a selected test battery with bacterium, algae and crustacean is proposed; (3) the eco-toxicological approach is useful in the hazard and risk assessment of discharges into receiving waters; (4) modelling has proved to be useful in evaluating the impact of effluents on the receiving waters and also suggested management actions and identified risk areas.
