Evaluation of airborne particulate matter pollution in Kenitra City, Morocco

Abstract

Two size fractions of atmospheric particulate matter < 2.5 µm and 2.5-10 µm were collected in Kenitra City from February 2007 to February 2008. The sampling was done using a Gent Stacked sampler on nuclepore polycarbonate filters and the collected filters were analyzed using Total Reflection X-Ray Fluorescence (TXRF) and Atomic Absorption Spectroscopy (AAS). The particulate matter trends show higher concentrations during the summer as compared to other seasons. The highest concentrations were obtained for Ca in coarse particles and Fe for fine particles. However, the lowest concentrations were observed for Cd in both particulate sizes. The principal component analysis (PCA) based on multivariate study enabled the identification of soil, road dust and traffic emissions as common sources for coarse and fine particles.

Trace Metals and Source Identification of Air-Borne Particulate Matter Pollution in A Nigerian Megacity

“…Entrained dust is expected to contribute more to particulate loadings in an environment such as Lagos with many unpaved roads and walkways. PM mass concentrations in this study were similar to those reported for urban sites in Ethiopia [25], Morrocco [26] and Kenya [27]. Table 1 displayed average concentrations, enrichment factor (EF) and pollution indices (PI) of twenty-four elements (Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Se, Br, Rb, Sr, Zr, Cs and Pb) detected in both particulate sizes.…”

Exposure to Air Pollution from Road Traffic and Incidence of Respiratory Diseases in the City of Meknes, Morocco

“…According to a WHO study on urban air pollution, all the studied Moroccan cities exceed the recommended thresholds for suspended particles (PM10 and PM2.5), namely Casablanca, Marrakech, Tangier, Meknes, Fez, Sale, and Safi [12]. This finding has also been raised in different urban areas of the Kingdom by studies that have assessed the quality of urban air, focusing on various pollutants [13][14][15][16][17][18][19][20][21][22][23]. Thus, the eco-epidemiological studies Casa-Airpol [24] and Mohammadia-Airpol [25], have revealed the possible health impacts caused by this form of pollution.…”

Short-term exposure assessment to particulate matter and total volatile organic compounds in indoor air during cooking Ethiopian sauces (Wot) using electricity, kerosene and charcoal fuels

“…Generally, among the substances in polluted air, particulate matter (PM) with different aerodynamic diameters and total volatile organic compounds (TVOC) are major components and they are a health concern in the world nowadays. 16,17 Carbon-based compounds that have high vapour pressures and significantly vaporize and enter the atmosphere are called volatile organic compounds (VOCs). 18 TVOC and PM with different aerodynamic diameters released during the combustion of biomass fuel and traffic emissions are a significant problem for the developing world in general and Ethiopia in particular.…”
