Abstract

Surface sediment samples were collected at 104 stations in 34 different locations in seasonal periods in 2013–2014 on the southeastern coasts of the Black Sea. Nickel concentrations were measured with ICP-MS after microwave digestion and were higher in two seperate region than that of others. Relatively high Ni concentrations were found in Bafra (148 ± 18 mg/kg), Dereköy (147 ± 24 mg/kg), Canik (95 ± 35 mg/kg), Çaltıburnu (129 ± 13 mg/kg), Çarşamba (127 ± 4 mg/kg), Terme/Ünye (94 ± 28 mg/kg), Akçaabat (95 ± 13 mg/kg), Çarşıbaşı (77 ± 14 mg/kg), Vakfıkebir (64 ± 5 mg/kg) and Görele (53 ± 15 mg/kg). Nickel concentrations were higher than Effects Range-Medium (ERM) limits in the western and middle part of the region. Ni enrichment levels in sediments were calculated from both core data and earth crust values as a background. It was determined that the enrichment factors found by using earth crust values produced quite misleading results due to the geological variation of the region. It is also concluded that Ni concentrations in marine sediments of the southeastern coasts of the Black Sea are related to terrestrial geological structure.

摘要

2013-2014年期间，在黑海东南沿海的34个不同地点的104个站点上收集了地表沉积物样本。微波消解后，ICP-MS测定镍的浓度，在两个独立的区域中镍的浓度高于其他区域。在Bafra（148±18 mg / kg），Dereköy（147±24 mg / kg），Canik（95±35 mg / kg），Çaltıburnu（129±13 mg / kg），Çarşamba（127）中发现较高的Ni浓度±4 mg / kg），Terme /Ünye（94±28 mg / kg），Akçaabat（95±13 mg / kg），Çarşıbaşı（77±14 mg / kg），Vakfıkebir（64±5 mg / kg）和Görele （53±15mg / kg）。在该区域的西部和中部，镍的浓度高于影响范围-中等（ERM）的限值。根据核心数据和地壳值作为背景，计算了沉积物中的镍富集水平。经确定，由于该地区的地质变化，使用地壳值发现的富集因子产生了相当误导的结果。还得出结论，黑海东南沿海海洋沉积物中的镍浓度与陆地地质结构有关。
