TRUJILLO-GONZALEZ, Juan Manuel  e  TORRES-MORA, Marco Aurelio. ASSESSMENT OF HEAVY METALS IN ACCUMULATED ROAD DUST IN THREE SECTORS OF THE CITY OF VILLAVICENCIO, COLOMBIA. Luna Azul [online]. 2015, n.41, pp.296-308. ISSN 1909-2474.  https://doi.org/10.17151/luaz.2015.41.16.

Urban dynamics derived from city growth and the population demands for transportation, food production, goods and services in general, are among the responsible on the generation of contaminating factors, where one of them is the presence of heavy metals in accumulated road dust. In this sense, the current study seeks to evaluate the pollution by presence of heavy metals (Pb, Zn, Ni, Cu, Cr, and Cd) in road dust from three sectors on Villavicencio -Meta- (sector Anillo vial sector, Buque sector and Porvenir sector). Among the obtained results, the metals abundance for each sector was as follows: Porvenir (SP), followed by sector Anillo vial (SA) and Buque (SB). The study showed that concentrations of heavy metals in road dust are related to the dynamics of each of these sectors.
