Discussion of trends in the ATMP category

The results do not show significant biodegradation in the short term. Based on evidence from a number of studies ATMP and its salts are considered to be essentially non-biodegradable by WWTP organisms, though the soil degradation result implies that it would be unreasonable to assume no degradation in the environment. There is evidence of degradation mechanisms that could prevent long-term persistence.
