Effects of air pollution on hematological parameters in passerine birds.
The effects of atmospheric air pollution on some hematological, and bioquimic parameters, of passerine birds were analyzed. The studies were undertaken in the area of Cercs (polluted area in Spain), where there is a coal-fired power plant that emanates SO2, NOx, and particles, and the area of St. Jaume de Frontanya (nonpolluted area) located 40 km from the area of Cercs with similar climatology, relief, and altitude, but without air pollution. The results showed that there was a significant decrease in the erythrocyte count, and an increase in erythrocyte size in specimens from the polluted area. An increase in pre-albumines and a decrease in beta-globulines in Emberiza cia was observed, while an increase in transaminases (GOT and GPT), and a decrease in weight in Turdus merula from the polluted zone was observed.
