Metallothionein and lipid peroxidation as markers to assess health status of chronically oiled Magellanic penguins in Argentina Acta Toxicol. Argent.
Romero,María Belén; Polizzi,Paula; Chiodi,Leila; Robles,Alicia; Rodríguez Heredia,Sergio; Gerpe,Marcela.
Chronic oiling affects seabirds, with short (individual survival) and long-term (dynamics of population) effects. Magellanic penguin is the most affected species in Argentina. The aim was to evaluate the use of blood biochemical-molecular biomarkers (MT and TBARs) to assess health status of Magellanic penguin exposed to chronic environmental oiling, in addition with routine hematological analyses (differential WBC count and PCV). Oiled specimens presented significant higher RBC metallothionein and TBARs concentrations than those from shelter; while routine hematological parameters were within normal levels for penguins and did not show any difference between both groups. These results demonstrated the higher sensibility of both biomarkers, evidencing...
