title: Hazard identification for 3,5-dichlorophenol in the aquatic environment.
abstract: The risk assessment of substances in various environmental compartments is essential for their proper, safe and environmentally friendly production, handling, use and final deposition or destruction. Hazard identification is an important part of risk assessment. The aim of our research was to present a methodology for the hazard identification of substances dangerous to the aquatic environment according to the 93/21/EEC Directive relating to the classification, packaging and labelling of dangerous substances, from the adverse effect assessment of chemicals in European Union. A battery of toxicity tests and biodegradability studies with 3,5-dichlorophenol were performed. The substance was classified as toxic to aquatic organisms with possible long-term adverse effects. The presented methodology assures reliable data for the classification and labelling of substances according to their harmful effect on aquatic biota, suitable for the competent authorities at the national and EU level.
