About Paper:

The existence of air and noise pollution in Africa is a growing concern, being that the identity of these particles are unknown, thus their health advantages or disadvantages is unknown as well. The record and identification of these coarse particles in the air is the center of this project. Using a high-power energy-dispersive X-ray fluorescence (EDXRF) device, air filters collected from over two residential sites in Accra, Ghana was used for the assessment of heavy metals concentrations, as well as lead (Pb) and nickel (Ni) speciation in airborne particulate matter (PM10). Particulates, also known as atmospheric particulate matter, are microscopic particles of solid or liquid matter that are suspended in the air. Types of atmospheric particles include suspended particulate matter, such as respirable and inhalable coarse particles, noted as PM10: coarse particles with a diameter of 10 micrometers (?m) or less; fine particles, noted as PM2.5, with a diameter of 2.5 ?m or less; ultrafine particles, with a diameter of 100 nm or less, and soot. The EDXRF was calibrated for the detection of the particles within these air filters by way of utilizing sample standards spotted at different concentrations for their detection using the XDR machines present in the labs. In order to measure the air particles, air filters are loaded into the XDR machines and run in 5 hour intervals. Keywords: [no keywords provided]
