Biodegradation is the process of degradation of organic components. Biodegradable profiles of chemicals are important as these compounds can stay for a long time in the environment, causing distinct adverse effects. In this endpoint, biodegradation is analysed on chemical compounds following the Japanese Ministry of International Trade and Industry (MITI) protocol. Under this protocol, compounds are distinguished between having and not having ready biodegradability based on biological oxygen demand (BOD) values.
