During 2016, 45 specimens of barbel (Barbus barbus (Linnaeus, 1758)) and 45 specimens of bleak (Alburnus alburnus (Linnaeus, 1758)) are collected and examined from the Danube River. The aim of the study is to analyse the lead content in sediments, tissues and organs of two fishes that inhabit different water levels and in their common parasite - P. tereticollis from the Bulgarian section of River Danube. New data for the lead contents in sediments, parasites, tissues and organs of barbel and bleak from the Danube River are presented. From the tissues and organs of the studied fish specimen B. barbus, the lowest concentrations of lead were found in skin, while in A. alburnus the lowest concentrations of lead were found in muscles. The acanthocephalan Pomphorhynchus tereticollis showed significantly higher content of lead than its hosts tissues and organs. Bioconcentration factor for lead (Pb) in the tissues and organs of barbel and bleak and their common parasite Pomphorhynchus tereticollis were presented and discussed with respect to their content in sediments. Highly significant correlation (p<0.01) was fixed for relationship between P. tereticollis Pb-Skin Pb for Barbus barbus. Highly significant correlation (p<0.01) was also fixed for relationship between P. tereticollis Pb-Sediments Pb for Alburnus alburnus.
