title: Distribution, sources and characterization of polycyclic aromatic hydrocarbons in the sediment of the river Gomti, Lucknow, India.
abstract: Sediment samples were collected for PAHs analysis (upstream, midstream and downstream) from the bank of the river Gomti in Lucknow city, India during 2005-2007. Total concentration of the PAHs ranged from 0.068 to 3.153 microg/g dry weight. A correlation existed between the sediment organic carbon content (f(OC)) and the total PAHs concentration with a correlation coefficient (r(2)) of 0.788, suggesting that sediment organic carbon content played an important role in controlling the PAHs levels in the sediments. According to observed molecular indices, PAHs contamination in the river Gomti seems to be originated both from the high temperature pyrolytic process as well as from the petrogenic source, indicating a mixed PAH input pattern.
