Atmospheric Physics; Air Pollution Monitoring and Analysis Using Purple Air Data

Abstract

Air pollution has become one of the agents that leads to the cause of life-threatening diseases in our contemporary world.  Among the major air pollutants is the Particulate Matters PM_2.5 and PM_10.0. Long-time exposure to fine particles PM_2.5 and PM_10.0 in the environment has been linked to serious respiratory and cardiovascular diseases. The purpose of this research is to find the concentration of PM in some selected areas in Nigeria (Africa) namely; Lagos, Rivers and Abuja using Purpleair real time data for 12 weeks duration from 1^st November 2021 to 31^st January 2022. Findings have shown that among the study areas, Port Harcourt has the highest concentration of Particulate Matters followed by Abuja with a 12-weekly average PM_2.5_CF1, PM_10.0_CF1 and PM_2.5_ATM to be 87.80 µg/m³, 101.76 µg/m³ and 63.15 µg/m³ respectively while Abuja has an average PM_2.5_CF1, PM_10.0_CF1 and PM_2.5_ATM values of 70.51 µg/m³, 86.21 µg/m³ and 52.07 µg/m³ respectively. It was also found that the relationship between PM_2.5 and PM_10.0 showed a positive correlation with R = 0.99 indicating strong linear relationship.
