This study focuses on the enrichment and degree of contamination of heavy metals (Al, Co, Cu, Cr, Fe, Pb, Mn, Ni and Zn) in contaminated sediment environments at the Mid-Black Sea coast of Turkey. Pollution by these metals were examined using several calculation methods: enrichment factors, modified degree of contamination, pollution load index and geoaccumulation index. For this purpose, in addition to physical and chemical parameter analyzes, heavy metal concentrations were measured by inductively coupled plasma- optical emission spectrometer (ICP-OES) in water and sediment samples collected at five different points for two periods. Sediment enrichment factor, contamination factor, pollution load index, and geoaccumulation index were calculated to evaluate the contamination degree and influence of human activities, chemical and microbiological pollution, synthetic organic contaminants, fisheries resources, aesthetic and recreational activities on heavy metals. It was determined that most of the heavy metal deposits in the sediment were one of the causes of pollution at sampling points.
