Influência da arborização e da edificação na dispersão de material particulado respirável em cidade costeira altamente urbanizada (Fortaleza, CE-Brasil)

Abstract

The present article aims to address the influence between the index of vegetation and edification with respirable particulate matter levels (PM 2.5μm) and atmospheric conditions in areas used for sports and leisure practices in the urban center of Fortaleza, CE, with a view to improving or worse weather conditions at locations predominantly occupied by vegetation or buildings. Thus, primary data of the concentrations of PM2.5 with active sampling and meteorological data were collected with a portable meteorological station in 7 sampling points distributed in the Municipality. The vegetation and edification indexes were made through ArcGIS Software, consisting of the mapping and delimitation of the coverage area by crowns of trees and buildings at the selected sampling points. Thus, the statistical correlation of the data was performed, where as a result the types of correlations were found, classifying them as positive or negative and strong or weak.
