Abstract

Due to respiratory and cardiac problems associated with particulate matter (PM) in the atmosphere, analyze the concentration and the chemical composition of Total Suspended Particles (TSP) and Particulate Inhalable (PM10) is relevant to check the air quality of a site. The objective of this study was to determine the chemical composition of TSP and PM10, and know the possible sources of these metals by statistical analysis in a region of the city of Limeira, Brazil. The monitoring was carried out with PM Samplers High Volume (Hi-Vol-TSP and Hi-Vol-PM10), installed at the monitoring station of the Faculty of Technology / UNICAMP. The samples were collected from March 2013 to August 2014, every six days for 24 h, using glass fiber filters. Among the meteorological variables, temperature and humidity were the most affected in both PM, the results showed that when there was an increase, the concentrations of particulates decreased. For chemical determination, the chosen technique was Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES), for its efficiency, high sensitivity, and determine various elements in a few seconds. Were analyzed ten metals of interest, Cd, Ca, Cr, Cu , Fe, Mg, Mn, Na, Zn and Pb, including Cd, Cr, Pb and Zn were not quantified in any of the samples. For both particulates, Ca, Fe and Na (5, ugm³, 3,98 ug/m³, 13,28 ug/m³ respectively for the TSP and 2,94 ug/m³, 1,96 ug/m³ and 7,80 ug/m³ respectively for PM10) were found in higher concentrations. By Principal Component Analysis (PCA) and cluster analysis (CA), the main source of metals in TSP is the soil, and the PM10 can be ground and resuspension of dust from vehicular traffic (AU)
