Chemical Characterization of PM2.5 at Rural and Urban Sites around the Metropolitan Area of Huancayo (Central Andes of Peru)

Abstract: The purpose of this study was to determine PM2.5 mass concentration and the contents of trace elements and water-soluble ions in samples collected inside the Metropolitan area of Huancayo. Four monitoring stations were installed at three urban areas (UNCP, HYO, and CHI) and one rural (IGP). The sampling campaign was carried out from March 2017 to November 2017. The PM2.5 content was determined by gravimetric method, and fifteen trace elements (TE) and seven water-soluble ions were detected by inductively coupl… Show more

“…The mean air concentration of Pb at Rio Seco was 51 ng/m 3 , 11 to 25 times higher than the other sites (2.0 to 4.6 ng/m 3 ), and the average mass concentration of 277 ppm was also an order of magnitude higher than the other sites (34-46 ppm). The Pb air concentrations at Rio Seco were similar to those observed at some heavily industrialized areas in Peru, such as Huancayo, in which 24-153 ng/m 3 Pb were observed[33]. The elevated concentration and the strong variations of Pb concentrations among the four sites suggest the Pb at Rio Seco could be almost entirely originated from local emissions.…”

“…El modelo AERMOD genero concentraciones de la dispersión de PM2.5 en los receptores discretos (CHI, HYO y UNCP), para HYO (Distrito de Huancayo) donde se tiene mayor nivel de concentración debido que predomina la presencia de 100 pollerías, seguido de la UNCP (Distrito de El Tambo) con 59 pollerías y registrando en CHI (Distrito de Chilca) 35 pollerías. La diferencia entre lo medido por las estaciones de monitoreo de calidad de aire en CHI con lo generado por el modelo AERMOD se debe a que se analizó los aportes de emisiones de PM2.5 de pollerías y no de las demás fuentes de emisión, y está confirmado que los principales aportes contaminantes están relacionados con el polvo del suelo y las fuentes vehiculares (Huamán et al, 2019) Figura 5. Comparación de concentraciones de PM2.5 de estaciones de monitoreo de calidad de aire y los generados por el modelo AERMOD Fuente: Los Autores.…”
