Evaluación de la concentración de partículas sedimentables en el área urbana de la ciudad de Loja

Abstract

Abstract: This titration work focuses on determining the concentration of material sedimentable particulate in the city of Loja, using a gravimetric method and comparing these results with the current Ecuadorian regulations. To achieve this, They distributed sampling points and installed sensors throughout the urban area, classifying them according to land use. The collectors, designed according to Method 502 and ministerial regulations, were monitored continuously for six months, collecting monthly samples for subsequent gravimetric analysis in the laboratory. HE quartz filters were used for the filtration of settleable particles, the concentrations according to standard gravimetric formulas. The results obtained They showed concentrations of sedimentable particles in different urban areas. To the compare them with the limits of the Ecuadorian regulations (TULSMA) and by the recommendations of the World Health Organization (WHO), it was observed that the majority of the stations exceeded local limits, although they met the standards of the WHO. Industrial and residential areas exhibited higher levels compared with commercial areas, which could be attributed to the influence of vehicular traffic, ongoing industrial activities and other possible sources of pollution.
