Preliminary Evaluation of Heavy Metal Contamination at Sediment in the Mid-Black Sea Coast of Turkey

Eurasian Journal of Engineering Sciences and Technology, cilt.1, ss.84-91, 2017 (Hakemli Dergi)

The heavy metal compound in the contamination sediments has begun to become a global problem for

developing countries like Turkey. Accordingly, it is aimed to make heavy metal analyzes of sediment

samples taken in the autumn and spring seasons from mid-Black Sea coast of Turkey (Dereköy, Canik,

Terme, Koşuköy, Fenerköy) and to be a reference for ecotoxicological investigations. The degree of

pollution in sediments has been tried to be determined using four different pollution indices. For

this purpose, five heavy metal concentrations were measured by inductively coupled plasma- mass

spectrometer (ICP-MS). The average concentrations (mg/kg) in the sediments were: 3.21 (chromium),

399.54 (iron) ,

0.37 (copper) , 5.47 (zinc) , 0.28 (lead). Sediment enrichment factor, contamination factor,

pollution load index, and geo accumulation 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 accumulations at the sediment layer

were the reason of pollution at the sampling sites.
