POLUIÇÃO DO AR POR MATERIAL PARTICULADO EM ÁREA INTRAURBANA NO RIO DE JANEIRO: ASPECTOS METODOLÓGICOS Air pollution by particulate matter in intra-urban area in Rio de Janeiro: methodological aspects

The aim of this study was to measure simultaneously the particulate matter concentrations of 10μm, MP10, in two sampling points separated by 280m within the campus of an Institute of Health Research, in city of Rio de Janeiro. The two points were chosen with different environmental physical parameters such as topography, forest attendance, highway proximity and buildings. The specific objective was to detect if there are significant variations in the values of pairs of concentrations measured at the low spatial resolution. Were taken 16 samples for two months, lasting between 4 and 6 hours for each daytime exposure, at the time of large circulation of vehicles. It was concluded that the average values of the concentrations at each sampling point differences in this small scale. In addition, the obtained values were above average recommended by the World Health Organization and considered inadequate by program of monitoring in the air of government of Rio de Janeiro. * Contato com os autores: 1 e-mail: pereira.jlg@gmail.com ( J.
