✦ Synopsis

The risk assessment of two kinds of wastewaters from a hardboard mill were determined by acute toxicity tests. Three different bioindicators-water fleas from a local stream (Daphnia pulex ), local fish hatchery specimens (Salmo gairdneri ), and a bacterial test (Vibrio fischeri Microtox test) were considered. The three tests showed a wide range of sensitivities and presented different but compatible LC 50 /EC 50 values, with S. gairdneri being the most sensitive. The obtained toxicity values could serve as a reference to evaluate the toxicity of wastewater from this type of industries.
