Sources and contamination status of PAHs in sediments of Cochin estuary, India. ∑ PAHs ranged from 194 to 14,149 ngg− 1 dry weight. The study revealed petrogenic and pyrogenic sources of PAHs. LMW PAHs increased several fold in monsoon posing sediment contamination. Carcinogenic PAHs were low and remained below the effective range low (ERL) values.
