lives were estimated with the PBT profiler (US-EPA) which calculates
half life values from ultimate biodegradation
estimations in the Biowin
included in BIOWIN. The calculated half life values for Acetyl tributyl
8.7 days for surface water and 78 days for sediment. To account for the
slower biodegradation under anaerobic conditions in the deeper layers of
the sediment, the overall half life in sediment is estimated to be about
9 times higher than the half life in water. The calculated result has no
impact on classification but can be used for risk assessment.
