Spatial distribution and temporal trends of polycyclic aromatic hydrocarbons (PAHs) in sediments from Lake Maryut, Alexandria, Egypt Conference Paper uri icon

abstract

  • Surface and core sediments from Lake Maryut, Egypt, one of the most polluted lakes in Egypt, were analyzed for polycyclic aromatic hydrocarbons (PAHs). The total PAHs concentrations (39 PAH compounds) in surface sediments ranged from 106 to 57,800 ng/g. The most polluted areas are distributed in areas which are mainly influenced by municipal sewage and industrial effluent discharges. PAH concentrations were higher in comparison with those reported for riverine/estuaries systems around the world. Molecular indices, such as petrogenic index, MP/P, HMWPAH/LMWPAH, A-PAHs/P-PAHs, FL/FL+PY, BaP/BaP+C, IP/IP+BgP, and Per/(penta-aromatics) were calculated to evaluate different hydrocarbon origins and their relative importance. Temporal trends of PAH concentrations in both cores sediments was influenced by input pathways and followed the economic development and the environmental policies of the Egyptian Government in the last 15 years. Finally, PAH levels in sediments were compared with Sediments Quality Guidelines for evaluation probable toxic effects on organism.
