The distribution, composition and sources of PAH mixtures in the sediments of the Gulf of Gemlik, sea of Marmara, and in a freshwater lake at its eastern extension, indicate characteristic spatial variability depending on various anthropogenic inputs. While atmospheric inputs are similar for both cases, other contributions are related to the spatial characteristics of riverine and terrestrial inputs and other activities such as shipping, fishing and agriculture. On the basis of several diagnostic criteria and principal component analysis -multiple regression models used to assess the type of process through which PAHs were generated, pyrogenic origin is dominant, even petrogenic PAHs also occur in combination with pyrogenic PAHs.
