Radionuclides and Potentially Toxic Elements in Sediments from the Northern Bulgarian Black Sea Coast

This paper presents data on the content of toxic elements (Mn, Ni, Zn, Cu, Pb, As, Cr, Cd and Co), technogenic (137Cs, 134Cs) natural radionuclides 238U 232Th series (234Th, 226Ra, 210Pb, 232Th) 40K in sediments collected from ten sampling stations along northern Bulgarian Black Sea coast for a period more than twenty years. Measurements were made by Gamma Spectrometry Inductively Coupled Plasma Mass Spectrometry. The results show that nuclides concentration strongly depend nature. obtained create database concentrations Northern can be used assessment ecological status marine environment whole coastal zone.
