Comparative study of the years 2017, 2018 and 2019 of PM 10 particle sampling of the frontera, Comalcalco and paraíso municipalities

Abstract

Air pollution is currently one of the greatest health risks. Among the effects that have been associated with atmospheric pollution are increases in respiratory and cardiovascular diseases, which are generated by fixed and mobile sources. One of the main pollutants in the atmosphere is particulate matter, which is a complex mixture of substances in a liquid or solid state that remains in suspension for a certain period of time. Due to this, the following work was carried out to evaluate the periods of highest concentrations of PM10 particles of the years 2017, 2018, and 2019 and compare them with meteorological data; temperature, and humidity of the municipalities of Centla, Comalcalco, and Paraíso. To achieve the development of this research, the data from each of the meteorological settled stations were downloaded, in order to give each one a previous treatment of the data in Excel by averaging the sampled days. For the treatment of the data, an Excel database was created to later manage them in the Minitad software to obtain the scatter plots where the concentrations of each of the municipalities were compared. In conclusion, we can say that the only municipality that exceeded the Metropolitan Air Quality Index (IMECA) was the municipality of Comalcalco where 11 dates were presented that exceeded the LMP, with values ranging from 76 µg /m3 to 110 µg /m3 . In graphs 4, 5, and 6, we can say that despite having ascending regression lines and positive correlations ranging from r= 0.1 to 0.4, we could not interpret that there is a correlation between both variables. As graphs 7, 8, and 9 show, we could also observe ascending and descending regression lines with mostly negative correlations ranging from r= -0.1 to -0.4, so we could say that their correlation is inverse, that the higher the increase in relative humidity, the lower the concentration of particulate matter.
