Surface water samples were regularly sourced for a period of 18 months; February 2013 – July 2014, from five (5) sampling stations on the Falcorp mangrove swamp and Ifie creek, respectively. The water samples were subjected to PAH and PCB analyses which were conducted in accordance with standard procedures which included; gas chromatograpy coupled with flame ionization or electron capture detector. The collated data were subjected to statistical analysis and multivariate analysis, respectively. The differences in the mean Naphthalene, Acenapthylene, Acenapthene, Fluorene, Fluranthene, Pyrene, Chrysene, Benzo[k]fluranthene, Benzo[k]pyrene and Dibenzo[a,h]anthracene values recorded across the five (5) stations was statistically insignificant.................................................................................................................................
