“…The sources of Ce were attributed to purely anthropogenic origins while the main source of Cd in the atmosphere was linked to vehicular tires. The observed concentration of Pb was found quite close to reports from other studies . On the average, the number of elements present was almost double than the US EPA limits for urban areas.…”

Like other Asian countries, Pakistan is facing the issue of air pollution due to rapid urbanization, enormous transportation increases, and other related human activities. Moreover, continuously increasing emission sources have not only raised pollutant concentrations but also their types, thus damaging both human health and the environment. Faisalabad is the third largest megacity of Pakistan and its state of air quality is getting worse due to factors such as industrialization, high traffic volumes, and extensive fossilfuel-burning activities. This review article aims to highlight the present status of air pollution in this city with special reference to particulate matter, elemental profiles, gaseous pollutants, organic-inorganic particulate contents as well as their sources. The concentration levels of these entities were also compared with other national and international cities, and related environmental standards. It is found that current levels of these pollutants are beyond safety limits as specified by various environment protection agencies and organizations. Several weak aspects and gaps are also identified along with suggestions for improvements of the present situation and directions for future research.

“…The presence of Yb, Cs, Sc, Rb, Co, Eu, La, Ba, Zn and Hf indicated their geological origin, while Sc was considered to be arising from coal burning. The presence of Cr, Fe, Ce, Pb and Cd was attributed to anthropogenic activities (Qadir et al, 2012). Schneidemesser et al (2010) ) and several other toxic metals (Schneidemesser et al, 2010).…”

In the present study, analysis and source apportionment of the elemental composition of PM 10 was conducted in the urban atmosphere of Karachi. Trace elements such as Ni, Ba, Cd, Ca, Mg, Cr, Mn, Fe, Co, Cu, Sr and Ti were measured. The PM 10 concentration ranged from 255 μg m -3 to 793 μg m -3 , with an average of 438 ± 161 μg m -3 . Among the various elements analyzed, concentrations of Ca, Al and Fe were the highest (> 10000 ng m -3 ), followed by Mg and S (> 1000 ng m -3 ). Elements such as Zn, P, Cu, Pb, Mn, Ti, Sr and Ba demonstrated medium concentrations (> 100 ng m -3 ), whereas the lowest concentrations were found for elements such as Cr, Ni and Se (> 10 ng m -3 ). The Positive Matrix Factorization (PMF) model identified five possible factors that contributed to PM 10 , namely, biomass burning, coal combustion, resuspended road/soil dust, vehicular emissions and industrial dust. Industrial dust was the highest contributor (23.2%) to PM 10 followed by Biomass burning (23%), Vehicular emissions (22.2%), Coal combustion (21.7%) and Re-suspended dust (9.9%). A strong positive correlation (R 2 = 0.98) was observed between the model predicted PM 10 mass and the gravimetrically measured mass collected on filters.
