“…The degree of atmospheric pollution varies from region to region and from cities to cities (Sonibare et al, 2010). In Nigeria, due to population density coupled with intense industrial and commercial activity, the air pollution of Lagos city is of particular interest (Odekanle et al, 2016). Previous studies undertaken in Lagos have reported the significant impact of pollutants on the local air quality when compared with WHO standards (Efe, 2008;Odekanle et al, 2017).…”

“…One of such sources is road transportation. The extent of the significance of road transport as a source of specific pollutants at any point in time depends on the level of traffic and proximity of other sources of specific pollutants as well as meteorological parameters (Odekanle et al, 2016(Odekanle et al, , 2017Onat & Stakeeva, 2013). A study conducted by the Lagos Metropolitan Transport Management Authority, Lagos Metropolitan Area Transport Authority [LAMATA] (2002) on air quality revealed that vehicular activities contribute about 43% to the deteriorated air quality in Lagos.…”

“…The recorded indoor and outdoor inhalable particles in the study area (175.8 and 188.8 μg/m 3 ) were higher than the set limit, although greater concentrations, higher than 300 μg/m 3 , have been recorded in Bangladeshi households as well as in Aba, Port Harcourt, and Lagos–all highly industrialized Nigerian cities. 19 , 27 – 29 …”

Background Airborne particulates are an issue in many urban regions around the world and their detrimental impact on human health has increasingly become a public health concern. Objectives The aim of the present study was to examine particle pollution in an urban settlement in Nigeria. This study examines the extent, spatial variation, and sources of indoor and outdoor particulate matter (PM) concentrations in Ogbomoso, Nigeria. Methods The survey research method was adopted. Sampling included 385 buildings across selected precincts and different residential zones in the town of Ogbomoso. Particulate matter analytes (PM1, PM2.5 and PM10) within/around each building were measured with a particle counter and details on domestic utilities/practices were obtained with a questionnaire. Analysis of variance was used to determine inter-zonal variations in PM levels and simple linear regression was used to analyze the relationship between indoor and outdoor air quality. Results Indoor and outdoor respirable particle (PM2.5) concentrations were lower than the World Health Organization (WHO) Interim Target limit of 75 μg/m3, while concentrations of inhalable particles (PM10) were higher than the set limit of 150 μg/m3 for daily averages. Coarse particles dominated, with an accumulative PM2.5/PM10 ratio of 0.24. The inter-zonal analysis of PM concentrations revealed that indoor and outdoor PM levels varied significantly by residential zone (p = 0.0005; p = 0.01, respectively). Regression analysis showed a significant but weak relationship between indoor and outdoor PM levels (r = +0.221), while the coefficient of determination (R2 = 0.049) showed that only about 5% of the variation in indoor air quality was associated with outdoor air quality. Particle pollution inducers were identified in the residents' waste disposal methods and adopted fuels/energy sources, with firewood and charcoal linked with increased concentrations of particulate matter. Conclusions Air quality was relatively poor in the study area given observed particulate matter concentrations. Cleaner fuels, effective waste management systems and improved roads are needed to foster better air quality in the study area.

“…This growth has also encouraged an enormous increase in transportation. As in most cities in the world, the transportation sector in Lagos is one of the major sources of air pollution (Odekanle, Fakinle, Akeredolu, Sonibare, & Adesanmi, 2016). Factors such as traffic congestion, lack of emission controls on vehicles, and fuel quality have been found to contribute to the elevated vehicle emissions affecting air quality in big cities (Gakenheimer et al, 2002).…”

In response to the growing concern about the contribution of polycyclic aromatic hydrocarbons (PAHs) from vehicular activities in Lagos mega city and their effect on air quality, PAH emissions were estimated using the emission factors approach. To make these estimates, PAH emission factors were calculated from the profile ratio of four PAHs emitted from vehicle sources obtained from the European Environment Agency's emission inventory guidebook, whereas the total number of registered vehicles based on the type of fuel they use for a period of 10 years was obtained from Lagos State Bureau of Statistics. Vehicle emissions were estimated using a combination of individual emission factors, the total number of vehicles in use based on fuel type, and the average mileage covered. The average highest level of emission of PAHs of 3.542 kilograms (kg) for gasoline‐powered vehicles was obtained in 2013, whereas the average lowest level of emission of 2.679 kg was recorded for diesel‐powered vehicles in 2007. In the same manner, 2013 had highest annual average total emission of 6.384 kg, whereas the lowest annual total PAHs emission of 5.727 kg was recorded in 2007. It is therefore advised that effective control measure should be put in place by regulatory agency to prevent personnel exposure to these hazardous substances.
