Seasonal and offshore concentration variations for selected sixteen priority
pollutant polycyclic aromatic hydrocarbons (PAHs) in surface sediments and water of Car
Wash and Kisat areas of Winam Gulf, Lake Victoria, have been investigated. PAHs
concentrations in sediments and water range from 0.4 to 31.95 μg/g dry weight and 3.32 to
55.8 μg/L, respectively. Statistical analysis of the PAHs concentrations showed that the most
contaminated samples are found during rainy season (April, 2006), 5 m offshore for
sediments and 10 m offshore for water. Dry season (October, 2005) generally recorded
lower concentrations. The variations showed significant difference (p≤ 0.05) with season
and distance of sampling from the shore.
