Seasonal research of heavy metal accumulation on the species of brown algae Cystoseira barbata found on the shore of Giresun

In this study, heavy metal accumulation in the Black Sea Cystoseira barbata in collected from the region. Three different stations and seasonal collected Cystoseira barbata in Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, Pb examining the accumulation of metals were and compared with similar previous studies. Stations usually results in the highest values were observed in the Merkez stations. As a result of these factors is more than the population density of the Merkez station and the reason could be close to the station of the industry. Looking at the results as most winter seasonal Cr and Ni; Mn, Fe, Co, Cu, Zn, Cd, Pb maximum accumulation was observed in spring season.
