Seasonal variations of total PAHs were observed during this study. The highest concentrations were observed during
winter season while lower concentration observed during summer season (Table 5). Based on our data, the GIS
maps were representing the concentrations of total PAHs measured during different seasons (Fig.3).
The predominant light PAHs compounds were acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene
and carbazol. While the dominant heavy PAHs compounds were floranthene, pyrene, benzo(a)pyrene, benzo(a)
anthracene, and
benzo(k)flouranthene. Benzo(a)anthracene and benzo(a)pyrene are the most effective carcinogens
have been found (Patel et al., 2015).
