Contaminación atmosférica y aerobiología del casco urbano de Calceta-Manabí

Abstract

air pollution and noise generation represent environmental risk factors for public health in Calceta. Due to the lack of information on air pollutants, the objective of this work was to estimate the concentration of carbon monoxide (CO), sedimentary particulate matter (SPM), sound pressure level (SPL) and aerobic bacteria in the urban area of ​​the Calceta. 18 data collection points were established covering an area of ​​6.9 km2; the concentration of CO was measured with a portable detector; the MPS collection was carried out during 30 days continuously by passive method; for the NPS measurements, the 15-second method (Leq-15s) was applied; Aerobiology was performed in Petri dishes with nutrient medium. The concentration of CO in a sector of the urban area of ​​Calceta has an arithmetic mean of 5804,26 μg/m3 and according to the EPA this level is capable of affecting the population in general. The levels of SPM and SPL reflect the breach of the limits established in the national regulations for both pollutants. Bacterial concentrations were lower than 500 CFU/m3. The present study is a baseline in air quality that will allow in perspective the implementation of measures for the benefit of public health. Index Terms— Environmental monitoring, lung diseases, air
