N2 - Anthropogenic pollutants rarely occur in the environment as single constituents, thus combination effects rather than separate effects of pollutants are expected to occur in the environment. PAH contamination of soil is often associated with the presence of high levels of potentially toxic metals which may impact on PAH biodegradation.
