The present study aims to assess the biological effects of different
environmental pollution on the Asian clam Corbicula fluminea. Biomarkers
indicative of oxidative stress (superoxide dismutase, SOD; catalase,
CAT; glutathione peroxidase, GPx; glutathione reductase, GR; and the
phase II biotransformation enzyme glutathione-S-transferase, GST) were
measured in clams collected within the Serbian sector of the Danube
River Basin at three locations: Vinjica, Zemun and Bela stena. Clams
from Vinjica exhibited significantly higher SOD, CAT and GST activities
than clams from the other two locations (p<0.05), whereas GPx and GR
activities do not have such a marked pattern. An alteration in the
activity of SOD, CAT and GST reflects the presence of certain
pro-oxidative chemicals that can lead to oxidative stress in clams at
the Vinjica site. In conclusion, the noted antioxidant disparities among
clam populations from different locations reflected physiological
sensitivity of C. fluminea to environmental change, supporting its use
as a sentinel organism in biomonitoring investigations.
