Application Summary AI generated
This standard specifies a laboratory method for determining the acute lethal toxicity of industrial wastewater to freshwater fish, typically using species like zebrafish or fathead minnows. It is applied by environmental monitoring agencies and industrial facilities to assess the immediate toxic impact of effluent discharges on aquatic life, supporting regulatory compliance and wastewater treatment evaluation. The test measures the concentration of wastewater that causes 50% mortality (LC50) over a 96-hour exposure period.
