The aim of this study was to compare environmental quality in two sites of the river in Western Ukraine, rural (R) and industrial (I) during three seasons via a set of biochemical markers in carp Cyprinus carpio L. Upon comparing the values of the I-site with those of the R-site, we found that Mn- and Cu, Zn-superoxide dismutase (SOD) activities decreased and O-center dot production increased; metallothionein (MT) and glutathione levels increased in most cases, and acetylcholinesterase (AChE) activity decreased in summer. This confirms our hypothesis about continuous environmental press at the I-site. The higher activity of catalase and lipid peroxidation (TBARS), as well as the increased levels of vitellogenin-like proteins at the R-site, compare to the I-site in spring reflects the permitting effect of agricultural discharges. According to the results of PCA, the most sensitive biomarkers of pollution are MT, TBARS, and AChE in liver. (c) 2008 Elsevier Inc. All rights reserved.
