The aim of this work was to analyze the temporal behavior of the concentration profiles of PM2.5 (period 2014-2023) and PM10 (period 2010-2023) collected in five district of the Metropolitan area of Lima (MAL). The year 2016 and 2021 showed the highest annual averages for PM2.5 while PM10 reported higher concentrations in 2013, 2016, and 2021 for most stations. For PM2.5 higher peaks were recorded between May and September and lower peaks between January and March. For PM10, higher peaks were found of March-May and August-October, and lower peaks observed between January and June. Daily minimum and maximum values of PM2.5 ranged between 3.74 and 148 μg/m3, while PM10 ranged from 7.16 to 579 μg/m3, respectively. For hourly variations was observed peaks that occurs between 6:00 and 10:00 a.m. and between 6:00 p.m. and 11:00 p.m for both PMs. This information obtained will serve to make important social decisions.
