化学品 固有生物降解性 改进的MITI试验（II）
Application Summary AI generated
This standard specifies a laboratory test method (the modified MITI test II) for determining the inherent biodegradability of chemical substances in an aerobic aquatic environment. It is applied in chemical safety assessment and environmental risk evaluation, particularly for substances that may be released into water bodies. The test measures the ultimate biodegradation of a chemical by monitoring oxygen consumption or carbon dioxide production over a 28-day period.
