Ambient air quality in Cluj County is determined by the number of pollutants, including heavy metals represented by As, Cd, Cr, Cu, Hg, Ni, Se, Zn and especially Pb, especially due to the relatively large quantities found in the environment. Lead can’t be degraded naturally, affecting the environment and human health, including the accumulation in the food chain. The amount of lead in the ambient air can be determined theoretically from the emission inventories and in practice by laboratory processing of the filters that particulate matter sampling was performed, followed by the mineralization of samples and the determination of heavy metals by atomic absorption spectrometry (AAS). All the data in this article was obtained from activities carried out in collaboration with the Regional Agency for Environmental Protection Cluj-Napoca. Air Quality in Cluj County has been monitored between 2007 and 2011 by determining the concentration of Pb in particulate matter (PM10), determined gravimetrically with automatic monitoring stations for air quality. Emissions inventory conducted in collaboration with Regional Agency for Environmental Protection Cluj - Napoca showed that Pb emissions dropped significantly in recent years, in Cluj county. The paper concludes with recommendations to local government to reduce pollution in general and lead in particular.
