Resumen:
The golden mussel Limnoperna fortunei was used as a biomonitor of environmental pollution in the
Suquý´a River basin around Co´ rdoba City (Argentina). The sampling sites along the river were chosen
according to their increasing levels of pollutants (e.g. heavy metals) as well as biological oxygen demand
(BOD) and chemical oxygen demand (COD). A water quality index (WQI) was constructed from the
interaction of several normalized factors that affect the aquatic environment, such as the mentioned
pollutants and physico-chemical characteristics of the sampling sites. Activity changes of biotransformation
enzyme glutathione S-transferase (GST) and the antioxidant enzymes glutathione peroxidase
(GPx), glutathione reductase (GR) and catalase (CAT), after exposure to pollutants, served as biomarkers.
Membrane bound GST and antioxidant enzymes responded at the most polluted sampling site within 1
day showing increased activities lasting for 4 days. Further sampling was restricted due to no survival of
the animals. Antioxidant enzymes GPx, GR and CAT were sensitive responding to the different pollution
scenarios, showing good correlation to the chemical characterization.
