The effects of waterborne metals in water on the activities of blood
copper-zinc superoxide dismutase (CuZnSOD), catalase (CAT), glutathione
peroxidase (GSH-Px), glutathione reductase (GR),
glutathione-S-transferase (GST), and acetylcholinesterase (AChE), and on
the concentrations of total glutathione (GSH) and lipid peroxides
(TBARS) in the blood of dice snakes (Natrix tessellata) caught in
Obedska Bara, Sebia (control area), with snakes caught in Pancevacki
Rit, a contaminated area in Serbia were examined. The activities of CAT,
GSH-Px, GR and AChE, and the concentration of TBARS were significantly
decreased, while GST activity and GSH concentration were significantly
increased in snakes from the contaminated area compared to specimens
from the control area. Significantly increased concentrations of Al, As,
B, Ba, Ca, Cu, Fe, K, Li, Mn, Na, Ni and Zn in the water at the
contaminated area as compared to control area were detected. The metals
Ag, Bi, Cd, Co, Hg, In and Tl were not observed in any of the
localities. Cr, Mo and Pb were not detected at the control area but were
observed at the contaminated area. The concentrations of Sr were similar
at both sites. The concentration of Mg was 2-fold higher at the control
site than at the contaminated area. The obtained results show that most
of the investigated blood biomarkers correlate with concentrations of
metals present in the environment. These findings suggest that dice
snakes are sensitive bioindicator species for monitoring the effects of
increased metal concentrations in the environment.
