N2 - Sediment samples were collected from three different locations and analyzed for selected parameters to study the effects of selected sediment characteristics and contributing source areas on sediment PAHs concentration. For all cases, the particles in the size range of 180 to 355 μm were most dominant in the sediments. Sediment COD, percent of material weight loss on ignition (material composition analysis) and sediment PAH concentrations showed similar trends of smaller and larger particles associations with higher values than with the intermediate sizes. However, most of the mass of the PAHs were associated with the smaller and intermediate sized particles. Sediments affected by commercial area runoff were found to have higher concentration of PAHs than the sediments affected by noncommercial area runoff.
