GB/T 21856-2008
ActiveTesting of chemicals - Ready biodegradability - CO2 evolution test
化学品 快速生物降解性 二氧化碳产生试验
Application Summary AI generated
This standard specifies a laboratory test method for determining the ready biodegradability of chemical substances by measuring the amount of carbon dioxide (CO2) they evolve when exposed to microorganisms in an aqueous medium. It is applied in environmental risk assessment and regulatory compliance for industrial chemicals, detergents, and other organic compounds to evaluate their potential for ultimate aerobic biodegradation in natural aquatic environments. The test is commonly used by chemical manufacturers, environmental testing laboratories, and regulatory agencies to classify substances for hazard labeling and environmental safety approvals.
