The seasonal dynamics of Benzo[a]Anthracene, Pyrene, Benzo[b]Fluoranthene, Benzo[k]Fluoranthene, Benzo[a]Pyrene, Benzo(g,h,i) Perylene, Fluoranthene and Indeno(1,2,3-cd) Pyrene was monitored in the superficial sediments from Vridi canal over a year (from April 2014 to March 2015). In conducting this study, monthly sampling was doing at three different stations in this estuary, a collection of 36 samples over the study period. The extracts of these hydrocarbons, obtained from these samples according to MA.400-HAP 1.1 standard, were assayed by high performance liquid chromatography (HPLC) with UV/fluorescence detectors coupled to a GC-MS mass spectrometer. The results show the absence of Benzo (g,h,i) Perylene and Indeno (1,2,3-cd) Pyrene in these entities over the entire study period. The other six polycyclic aromatic hydrocarbons, with a strong seasonal dynamics, were detected in these substrates only in a few seasons and, this with relatively high concentrations (ranging between 0.020 ± 0.001 and 123.40 ± 6.17mg/kg per dry weight). As a result, significant seasonal mean values of &
