Estudio y evaluación del impacto antropogénico sobre los niveles de calidad del aire, previo y durante la pandemia del covid-19 en la ciudad de Cuenca.

Abstract

Abstract:Air pollution is defined as the presence of substances in the atmosphere that might cause damage to the human being. This work evaluated the impact in Cuenca city air quality, before and during the Covid-19 pandemic, due to human mobility restrictions. For this, the EMOV-EP company s air quality monitoring database in Cuencaas used, to evaluate quantitatively and qualitatively, each pollutant concentration in a temporal scale, based on the current environmental law. The research determined that the criteria pollutants (NO2, SO2, CO Y O3)lowered during the mobility restrictions 42%, 76%, 81% and 10% respectively, except for PM2.5whose reduction was minimum. It was concluded that the first ones were clearly anthropodependent, whereas PM2.5has a dependency onnatural causes. Finally, it was concluded that an action plan based on these restrictions don t generate a favorable impact in the air quality, conversely, it would generate damages in economic and social sectors in the country.
