Morphological and Chemical Composition of Total Particulate Matter in Region of Qena/ Egypt
Journal Title: IOSR Journal of Environmental Science, Toxicology and Food Technology (IOSR-JESTFT) - Year 2018, Vol 12, Issue 8
Abstract
This work concerns chemical constituents and morphology of total particulate matter (TPM) using scanning electron microscope SEM, coupled with energy dispersive X-ray (EDX). The samples of TPM are collected in Qena city, upper Egypt during the period from June 2016 to January 2017. Results indicated that the average mass concentration of total suspended particulate matter was 158.3 ± 40.1 μg/m3 , the winter average value was 182.5 μg/ m 3 , while the summer average value was 132.5 μg/m3 . In the entire study period TPM particles have irregular, spherical and aggregated shapes. Elemental analysis indicates that C, Si and Ca were the abundant elements in the particles followed by Al, Na and Fe amongst all the elements. Carbon soot particles were the dominants with high percentage in all the TPM samples. With respect to the crustal and mineral dust particles, Si rich particles associated with Al was present in major amount than other elements. The Ca rich particles were the second abundant. This indicates that TPM particles mainly originated from soil crust and anthropogenic activities.
