Comparison of metal uptake capacities of the brown algae Cystoseira barbata and ‎Cystoseira crinita (Phaeophyceae) collected in Sinop, Turkey.

Abstract

Cystoseira barbata (Stackhouse) C. Agardh, 1820 and Cystoseira crinita Duby, ‎‎1830 widely distributed and dominant in the Black Sea collected from Sinop coastal ‎zone to monitor the current situation of regional metal pollution during the 2015-2016. ‎ Macro-algae, sediments and seawater samples were analyzed for metal contents (Al, ‎As, Cd, Co, Cu, Fe, Hg, Mn, Ni, Pb and Zn) using inductively coupled plasma mass ‎spectrometry (ICP-MS). The methodology was provided by using standard reference ‎material BCR 279 – Ulva lactuca.‎ The general metal uptake of Cystoseira spp. displayed a tendency in the order of ‎Hg2 and BCF>5000) that was a good ‎indicator for Cystoseira species. As a result of measured values, it is seen that Sinop ‎region is below the pollution level. The observed results of the elemental accumulation ‎noticed that Cystoseira spp. could be used regularly as a bio-monitor of coastal pollution ‎in the study area.‎
