The QSARs estimated half-lives for biodegradation of styrene in water and sediment based upon BIOWIN Ultimate Biodegradation are 360 hours (15 days) and 3240 hours (135 days), respectively.


The QSAR models predicts timeframe within days-weeks for primary biodegradation of styrene and weeks for its ultimate degradation. The hydrocarbons QSAR model estimated half-life for styrene is 3.943 days.
