Determinación de aerosoles sedimentarias en el área urbana del cantón Saragur

Abstract

Abstract:The purpose of this titration study is to determine the concentration of settleable particulate matter (SPM) in the urban area of ​​the Saraguro canton, using laboratory methodologies that include the gravimetric method and the determination of metals present. It also compares the results obtained with current Ecuadorian regulations and those established by the WHO. The study began with strategic planning for the distribution of sampling points and the installation of collectors designed according to Method 502. They were continuously monitored for a period of six months, and SPM concentrations were recorded during the months of April, May, June, July, August, and September. The results revealed the presence of heavy metals such as cadmium, copper, and chromium, and the absence of lead. These findings indicate a potential risk to public health due to air pollution caused by these metals. The statistical analysis performed showed no significant differences in MPS concentrations between the sampled months. However, correlations were identified between MPS levels and the presence of metals, suggesting that human activities, especially vehicular traffic, could be influencing air quality.
