Abstract

Particulate matter (PM) is one of the most important pollutants present in the air, representing an environmental risk to health. Particles with a diameter of 10 microns or less (PM10), being inhalable, can penetrate and lodge deep in the lungs, contributing to the risk of developing cardiovascular and respiratory diseases, as well as lung cancer, mental illness, dermatitis, eye damage and even increased mortality rates. The objective was to determine the indoor air quality associated with the immission of particulate matter (PM10) in East Zone 2, an industrial sector located in the districts of San Juan de Lurigancho and Lurigancho-Chosica, Peru. To this end, the use of dual indicators is proposed: ecological and social. According to the ecological indicators explored, the average concentration of PM10 in outdoor air (CME) exceeded the limit of 100 μg/m3 established by MINAM. Although the CME median (93.7μg/m3; 95% CI=89.07-98.33) was below this limit, the upper quartile exceeded it, understood as point elevations of up to 131μg/m3 (Figure 2 ), potentially harmful to human health. Spearman's correlation coefficient of 0.921, obtained from the bivariate analysis between the daily average concentration values of outdoor and indoor PM10, prior to the installation of filters in the ventilation systems, is suggestive of the effect that the immission of ambient air can have with particulate matter as a vector of indoor air pollution. When considering the values of the average daily concentration, obtained in the 15 days after the installation of the filters (CMIFI), it is observed that the average concentration of PM10 in the interior decreased in relation to the previous fortnight. Spearman's correlation coefficient of 0.869 between the CMIFI and CME indicators allows us to propose that, in this second phase, indoor air quality was influenced to a lesser extent by particulate matter contamination in the ambient air, that is, there was less PM10 immission, thanks to the filtering process, which reduces the risk to the health of workers.
