Ecological Risk Assesment and Seasonal-Spatial Distribution of Trace Elements in the Surface Sediment of Trabzon Harbour, Turkey

摘要

A seasonal-spatial distribution and ecological risk assesment of the surface sediment are provided for Trabzon Harbour, located in the Eastern Black Sea Region. Sediments were collected from three stations, one of which was a control station, and a total of nine heavy metals were analyzed. In the sediment samples, concentrations of iron (Fe: 57.972 ± 1.226 − 116.250 ± 0.554 μ g ⋅ g~( − 1) DW), copper (Cu: 5.790 ± 0.250 − 14.770 ± 0.270 μ g ⋅ g~( − 1) DW), cadmium (Cd: 0.070 ± 0.016 − 0.232 ± 0.005 μ g ⋅ g~( − 1) DW), lead (Pb: 55.100 ± 0.540 − 4.652 ± 0.066 μ g ⋅ g~( − 1) DW), chrome (Cr: 9.232 ± 0.046 − 28.640 ± 0.377 μ g ⋅ g~( − 1) DW), zinc (Zn: 4.592 ±? 0.300 − 54.322 ± 0.437 μ g ⋅ g~( − 1) DW), arsenic (As: 2.702 ± 0.233 − 6.332 ± 0.186 μ g ⋅ g~( − 1) DW), manganese (Mn: 21.175 ± 0.374 − 41.465 ± 0.410 μ g ⋅ g~( − 1) DW), nickel (Ni: 9.272 ± 0.042 − 54.230 ± 0.158 μ g ⋅ g~( − 1) DW), total phosphorus (TP: 0.160 ± 0.003 − 0.250 ± 0.001 μ g ⋅ g~( − 1) DW), total nitrogen (TN: 0.111 ± 0.001 − 0.161 ± 0.001 μ g ⋅ g~( − 1) DW), organic matter (OM: 0.767 ± 0.010 − 1.750 ± 0,009 μ g ⋅ g~( − 1) DW), total organic carbon (TOC: 1.450 ± 0.001 − 4.407 style=.
