For this reason the effect of these pollutants on living organisms must be monitored accurately. Analysis of oxidative stress generated by exposure to pollutants can be used as a reliable biomarker; and House Sparrow (Passer domesticus) may be used as an ecological indicator due to its worldwide distribution, non-migratory status and its association with anthropic areas. In this study, several markers of oxidative stress have been evaluated in blood of House Sparrow using a non-invasive sampling method. Populations from urban and rural areas with differential pollution levels were analyzed. Results showed significant differences in two oxidative stress markers: haemoglobin (Hb) and total antioxidant capacity (TAC), both lower in urban populations. Environment pollution degree may affect oxidative stress status of erythrocytes, therefore these biomarkers could be a useful tool to evaluate the effects of pollutants on living organisms.engjournal articlehttps://www.sciencedirect.com/science/article/pii/S1470160X13003130restricted access598.8504.5Urban air pollutionBioindicatorHouse SparrowBloodOxidative stressNon-invasive methodAvesFisiología animal (Biología)Medio ambiente natural2401.20 Ornitología2401.13 Fisiología Animal
