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 μg⋅g−1 DW, copper Cu: 5.790 ± 0.250 − 14.770 ± 0.270 μg⋅g−1 DW, cadmium Cd: 0.070 ± 0.016 − 0.232 ± 0.005 μg⋅g−1 DW, lead Pb: 55.100 ± 0.540 − 4.652 ± 0.066 μg⋅g−1 DW, chrome Cr: 9.232 ± 0.046 − 28.640 ± 0.377 μg⋅g−1 DW, zinc Zn: 4.592 ± 0.300 − 54.322 ± 0.437 μg⋅g−1 DW, arsenic As: 2.702 ± 0.233 − 6.332 ± 0.186 μg⋅g−1 DW, manganese Mn: 21.175 ± 0.374 − 41.465 ± 0.410 μg⋅g−1 DW, nickel Ni: 9.272 ± 0.042 − 54.230 ± 0.158 μg⋅g−1 DW, total phosphorus TP: 0.160 ± 0.003 − 0.250 ± 0.001 μg⋅g−1 DW, total nitrogen TN: 0.111 ± 0.001 − 0.161 ± 0.001 μg⋅g−1 DW, organic matter OM: 0.767 ± 0.010 − 1.750 ± 0,009 μg⋅g−1 DW, total organic carbon TOC: 1.450 ± 0.001 − 4.407
