Additional information

Biodegradation is not a primary route of degradation for this substance. The substance is neither readily nor inherently biodegradable as demonstrated by 30% biological oxygen demand in an OECD 301D study after 28 days with no further loss observed after 84 days and 0% loss of non-purgeable organic carbon in an OECD 302A study. Numerous additional supporting studies, using CO2 and BOD to indicate biodegradation, show that the substance is not biodegradable. Studies that indicate extensive biodegradation based on indirect methods of analysis such as dissolved organic carbon likely over estimate biodegradation due to other mechanisms of removal such as precipitation, sorption, oxidation or photodegradation.
