1 Introduction
Dissolved organic matter (DOM), of allochthonous and autochthonous origin, is
a heterogeneous mixture of organic compounds, with molecular weights ranging from less than 100 to over 300,000 Da in natural waters (Hayase and Tsubota
1985; Thurman 1985; Ma and Ali 2009; Mostofa et al. 2009a). The DOM components are involved into key biogeochemical processes such as global carbon cycle,
nutrient dynamics, photosynthesis, biological activity and finally as energy sources
in the aquatic environments (Mostofa et al. 2009a, b; Hedges 1992). Among the
