Lake Koumoundourou is a shallow meromictic lake located ∼11 km NW of Athens It is surrounded by various industries and oil refineries which contaminate the lake by oil spills and leakage Moreover the lake receives freshwater from underwater springs plus drainage from industrialized catchment and Athens landfill Potential contamination of the lakes’ sediments in heavy metals and metalloids was assessed by means of enrichment factors EFs estimated against local preindustrial core sediment elements were normalized to loss on ignition EFs revealed that surface sediments were enriched in Pb ×102 Cu ×67 V ×51 Ni ×41 and other heavy metals The use of EFs is recommended as a reliable method for heavy metal contamination assessment provided that 1 element contents are corrected following a careful normalization procedure 2 local preindustrial sediment is used as reference and 3 reference sediment should be unaffected by diagenetic alterations
