Abstract

In autumn 2005 the sitespecific variability of cytosolic metal and protein concentrations in gills of European chub from the Sava River could be mostly associated with gill mass variability In spring 2006 the correlations of metals and proteins with gill mass were mainly nonsignificant and their sitespecific variability could be presumably associated with river water pollution The spring cytosolic concentrations of Zn Cu and Mn did not differ significantly between the sites medians 837–1134 μg ml−1 682–862 ng ml−1 and 559–686 ng ml−1 respectively Increased cytosolic Cd concentrations were obtained at Oborovo and Lukavec Posavski median 401 ng ml−1—the sites influenced by pollution sources from two major urban areas—compared with the remaining sampling sites median 193 ng ml−1 Cytosolic Fe concentrations were almost two times higher at Jasenovac median 1198 μg ml−1 compared with the concentrations at SavaZagreb median 672 μg ml−1 Labile Fe concentrations measured in river water with passive samplers indicated that cytosolic Fe concentrations in the spring possibly reflected waterborne Fe uptake The spring cytosolic protein concentrations decreased from upstream Otok Samoborski 272 ± 56 mg ml−1 toward the downstream sites Lukavec Posavski 148 ± 28 mg ml−1 possibly because of the influence of organic pollution and water toxicity The spring period seems to be a more appropriate season for the assessment of the river water pollution if chub gills are used as the target organThe financial support by the Ministry of Science Education and Sport of the Republic of Croatia Project No 09809829342721 is acknowledged This study was carried out as a part of the European FP6 Project Sava River Basin SARIB Sustainable Use Management and Protection of Resources INCOCT2004509160 The authors express thanks to all SARIB project participants for the help with fish sampling and dissection
