Toxicity of pure chemicals is assessed using respirometers by adding increasing concentrations to an active culture. The concentration at which oxygen uptake or gas production begins to decrease is known as the “threshold toxicant concentration.”

Physico-chemical parameters alone are not sufficient in obtaining reliable information on treated wastewater. Online toxicity monitoring must be performed in combination with routine chemical analysis. The assessment of biological effects of wastewater discharges in the ecosystems is today considered relevant and ecotoxicological tests identifying the ecological hazard are useful tools for the identification of environmental impacts.
