4.5. Bioaccumulation, Movement and Partitioning

Considering the bioconcentration factor (BCF) for fish and the octanol/water partition coefficient (Pow), the bioconcentration potential for styrene is low. As shown in Figure 7, the primary removal mechanism from water is volatilisation. The exposure of aquatic species will be limited to several hours when exposed to water, which is initially saturated with styrene. As previously indicated the mobility of styrene in soil is considered to be moderate to low. The primary mechanisms for styrene removal from soils are biodegradation, solubilisation by infiltrating water and, in shallow soils, volatilisation.
