Profile of air pollution by PM10 in the province of Kadiogo, Burkina Faso
Abstract
PM10 are one of the major air pollutants. There is a paucity of air quality data in Burkina Faso. The present study aimed at assessing the profile of air pollution by PM10 in the province of Kadiogo. Districts of Ouagadougou and rural communes of the province of Kadiogo were the subject to four campaigns of PM10 level measurement in the air, between November 15, 2016, and February 15, 2017, using DUSTMATE series DM 11932 (Turnkey, Cheshire, UK). Measurements of PM10 concentrations revealed high levels in districts 2, 5, and 6 while intermediate levels were observed in districts 4, and 11. For the rural communes, Koubri presented the lowest level of PM10 (86.80 µg/m3 ). The commune of Komsilga presented the highest maximum level (6469,43 µg/m3 ). The largest standard deviation (2532.65) was found in the rural commune of Koubri. Our results revealed that PM10 levels were higher than the WHO defined standards both in Ouagadougou and rural communes of Pabre, Koubri and Komsilga. Further investigations are therefore required to determine in addition to PM10, PM2.5, the levels of PM1, PM0.1 and TSP and their mechanisms of toxic action as well as their impacts on the health of the populations in Burkina Faso.
