“…The findings of the current study are consistent with those of Odekanle et al (2022), who detected non-permissible levels of PM2.5, SO2, and NO2 in ambient air in Lagos. The results are also in line with those of Owoade et al (2009) and Chiedu et al (2019), who reported non-tolerable levels of PM2.5 and traces of some elements in industrialized urban areas in Lagos. Similarly, Obanya et al (2018) detected non-permissible levels of PM2.5 and PM10 in Yaba Local Government Area, Lagos State.…”

Particulate matter (PM) exposure from ambient air has been implicated in several diseases, which necessitates periodic air monitoring in every dwelling place, particularly urban centers, to detect overexposure early. The main objective of this study was to determine the levels of PM2.5 and associated elements, namely carbon monoxide (CO), ozone (O3), and nitrogen dioxide (NO2) in Lagos, Nigeria. AnAerosol Mass Monitor was employed to quantify the concentrations of PM2.5, NO2, CO, and O3 at ten selected locations in the city, namely, Allen Avenue, Kolington, Isheri, Badagry, Opebi, Eti-Osa, Ajeniya, Awolowo, Orile, and Ajegunle. The values obtained were thereafter used to estimate the hazard quotient (HQ) of the average hourly dose (AHD) and average daily dose (ADD) exposures to the particles. The results revealed that PM2.5 levels in all the locations were above the 15µg/m3 permissible level recommended by the World Health Organization (WHO), except in Badagry (5.36µg/m3). NO2 was above the 25µg/m3 permissible level in all locations except in Badagry (6.11µg/m3) and Ajeniya (0.00µg/m3). Meanwhile, in all the locations, CO was above the tolerable level (i.e., >7µg/m3) while O3 was within permissible levels (i.e., <100µg/m3). The HQ of the AHD of the pollutants was less than the threshold of 1, but the HQ of the ADD was greater than 1 in many locations. It can be inferred from the results that daily exposure to PM2.5, NO2, and CO in the city can cause serious health consequences for residents. Agencies in charge of health and the environment in the city are advised to formulate policies towards pollution reduction.

“…Among the main industrial sources of Zn are electroplating, ore processing, smelting, and drainage from both active and inactive mining activities. The elements Cr and Cu are produced in iron smelting factories 98 . Elements like Cu, Zn, and Ni, which are often utilized in the steel and metal mechanics sectors, were found in all samples.…”

Meteorological factors play a crucial role in affecting air quality in the urban environment. Peshawar is the capital city of the Khyber Pakhtunkhwa province in Pakistan and is a pollution hotspot. Sources of PM10 and the influence of meteorological factors on PM10 in this megacity have yet to be studied. The current study aims to investigate PM10 mass concentration levels and composition, identify PM10 sources, and quantify links between PM10 and various meteorological parameters like temperature, relative humidity (RH), wind speed (WS), and rainfall (RF) during the winter months from December 2017 to February 2018. PM10 mass concentrations vary from 180 – 1071 µg m−3, with a mean value of 586 ± 217 µg m−3. The highest concentration is observed in December, followed by January and February. The average values of the mass concentration of carbonaceous species (i.e., total carbon, organic carbon, and elemental carbon) are 102.41, 91.56, and 6.72 μgm−3, respectively. Water-soluble ions adhere to the following concentration order: Ca2+ > Na+ > K+ > NH4+ > Mg2+. Twenty-four elements (Al, Si, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Co, Zn, Ga, Ge, As, Se, Kr, Ag, Pb, Cu, and Cd) are detected in the current study by PIXE analysis. Five sources based on Positive Matrix Factorization (PMF) modeling include industrial emissions, soil and re-suspended dust, household combustion, metallurgic industries, and vehicular emission. A positive relationship of PM10 with temperature and relative humidity is observed (r = 0.46 and r = 0.56, respectively). A negative correlation of PM10 is recorded with WS (r = − 0.27) and RF (r = − 0.46). This study’s results motivate routine air quality monitoring owing to the high levels of pollution in this region. For this purpose, the establishment of air monitoring stations is highly suggested for both PM and meteorology. Air quality standards and legislation need to be revised and implemented. Moreover, the development of effective control strategies for air pollution is highly suggested.

“…Furthermore, Zn had good correlation with Pb (R 2 =0.90, Fig. S4) at ULG, which were identified as the significant tracers of industries in Lagos (Owoade et al, 2009), while Zn was identified as the tracer of mobile sources in Hong Kong (Guo et al, 2009a). Moreover, the levels of Cd, Zn and Pb at ULG were much higher than those observed at TC (all p<0.05) (Table 1), indicating more severe pollution caused by industries at ULG.…”

“…Factor 5 at ULG was recognized as the source related to industrial processes due to the high percentages of Cd, Zn and Pb, as well as partial Cu and Ni. In Lagos, Cd was mainly emitted from paint industries, while Zn and Pb were related to the scrap and additives used in the electric-arc furnace section in iron and steel smelting industry (Owoade et al, 2009). Since no measurable EC and OC were found in this factor, we classified it as industrial-related emissions rather than vehicular emissions.…”
