Abstract 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 ug/g dry weight and 3.32 to
55.8 ug/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.
