Additional information

LAS and salts are conisdered biodegradable.

This class of substance that includes LAS-Na and Ammonium are also readily biodegradable and these can be considered as equivalent to purposes of environmental fate.

Biodegradation of LAS-Na in sediment is rapid.Mineralisation was best described by a First Order Model (r2 > 0.99), indicating that parent and metabolites were equally bioavailable to undergo mineralisation. The rate constant for mineralisation was 0.06 day-1.

Half-life in sludge-amended soil after application of sludge of LAS-Na was >7 -<22 days based on recovered LAS-Na.
