Are ready biodegradation tests effective screens for non-persistence in all environmental compartments?

Aug 16, 2023

Persistence assessment is a cornerstone of chemical hazard and risk assessment in numerous regulatory frameworks, as the longevity of a substance in the environment relates to exposure and ultimately the risk it poses. A chemical that is readily biodegradable is...
