Bioaccumulation and Environmental PersistencyNo relevant information is available regarding the potential of petroleum distillates to be bioaccumulated. However, its potential for bioaccumulation is dependent of the bioaccumulation potential of their individual components. In general, lower molecular weight alkenes display higher water solubility and do not tend to bioaccumulate, aromatics may exhibit a moderate tendency to bioaccumulate, and the higher molecular weights alkanes tend to bioaccumulate, as observed in aquatic organisms such as mussels and others after crude fuel spills containing several of the components found in petroleum distillates.
The volatile hydrocarbons tend to be photodegraded in the atmosphere. The hydrocarbons dissolved in water or retained on soil can be biodegraded by microorganisms. In general, the rate of biodegradation is higher for aromatics than for aliphatic hydrocarbons, and for lineal hydrocarbons than for branched or cyclic compounds. Degradation by aerobic microorganisms is usually faster than degradation by anaerobic microorganisms.
