This paper refers to the active biomonitoring moss bag of air quality of Ipatinga - MG, using Sphagnum capillifolium, determining the metals Al, Ca, Cd, Cr, Co, Cu, Fe, In, Li, Mg, Mn , Ni, Pb, Sn, Sr, Tl and Zn adsorbed on plant material through the analytical technique of Optical Emission Spectrometry with Inductively Coupled Plasma (ICP-OES). The self-organizing maps have proved useful to visualize the similarities and differences of samples and variables, making a positive correlation with the experimental observations. Both in the dry and in the rainy season, it was found that the majority of certain metals in plant samples were identified in the southern districts of this research, the regions predominant wind direction and close to local steel. In the dry period were higher concentrations of certain metals.
