Biomonitoramento passivo com casca de aroeira vermelha (Myracrodruon urundeuva Lorenzi Harri) para verificar a variabilidade espacial da poluição atmosférica em uma região do Distrito Federal, Brasil

Abstract

Biomonitoring is an alternative technique that uses living organisms to verify changes in the environment caused by pollution of water, air and soil. Focusing on atmospheric emissions at Fercal, located in the Federal District region, the present study aimed to collect samples of the bark of the species Myracrodruon urundeuva to verify the spatial variability of the chemical elements present in the study area. The principal component analysis (PCA) allowed to group the elements into three factors: factor 1: Zn, Fe, Al, S, and Ba; factor 2: Cu, P, Ca, and Sr; and factor 3: Mg and K. Factor 1 is the one that best describes the research object. This study has demonstrated the feasibility of the method of biomonitoring with the bark of aroeira vermelha (Myracrodruon urundeuva) as an instrument for measuring air pollution
