ActiveChemicals—Surface water-sediment Misgurnus anguillicaudatus toxicity test
化学品 地表水系统-沉积物中泥鳅毒性试验
Application Summary AI generated
This standard specifies a laboratory test method for assessing the acute or chronic toxicity of chemicals to the loach species *Misgurnus anguillicaudatus* in a simulated surface water-sediment system. It is applied in environmental risk assessment and chemical management, particularly for evaluating the ecological impact of pollutants on benthic organisms in freshwater ecosystems. The test is used by regulatory agencies and research institutions to determine safe concentration thresholds for industrial chemicals, pesticides, or wastewater discharges.
