“…However, the economic growth over the region drives up anthropogenic emissions. There are increases in industries, including gas flaring (Asuoha and Osu, 2015); local fuel-wood burning for stoves; and traffic Hadji et al, 2012;Liousse et al, 2014). Moreover, the increase in two-wheel vehicles, using very poor quality fuel is suspected to quickly worsen air quality (Ndoke and Jimoh, 2005;.…”

Abstract. Carbon monoxide, CO, and fine atmospheric particulate matter, PM 2.5 , are analyzed over the Guinean Gulf coastal region using the WRF-CHIMERE modeling system and observations during the beginning of the monsoon 2006 (from May to July), corresponding to the Africa Multidisciplinary Monsoon Analysis (AMMA) campaign period.Along the Guinean Gulf coast, the contribution of longrange pollution transport to CO or PM 2.5 concentrations is important. The contribution of desert dust PM 2.5 concentration decreases from ∼ 38 % in May to ∼ 5 % in July. The contribution of biomass burning PM 2.5 concentration from Central Africa increases from ∼ 10 % in May to ∼ 52 % in July. The anthropogenic contribution is ∼ 30 % for CO and ∼ 10 % for PM 2.5 during the whole period.

“…The dry season concentrations of pollutants were considerably higher than the rainy season concentrations and the noise pollution levels were very high too. Asuoha and Osu (2015) investigated the seasonal variation of meteorological factors and the impacts of gas flaring on air quality in the Delta Niger area(Ibeno,Onaa,Esit Eket and Umudike) and discovered a strong positive correlation between air quality parameters(Cl-,SPM and SO2) and meteorological factors(vapour pressure, relative humidity, temperature and precipitation) in the area. Asubiojo (2016) and Taiwo et al (2015) enumerated the major sources of pollution in Nigeria as natural (e.g.…”

Land use is the utilization and reordering of land cover for human comfort. This process disrupts the pristine state of the environment reducing the quality of environmental receptors like water, air, vegetation etc. Air pollution is introduced into the environment as a result of anthropogenic activities from commercial, industrial and residential areas. These activities are burning of fossil fuels for power generation, transport of goods and services, valorization of raw materials into finished products, bush burning, use of gas cookers, generators and electric stove etc. The introduction of pollutants into the planetary layer of the atmosphere has impacted negatively on the quality of the environment posing threat to humans and the survival of the ecosystem. In Lagos metropolis, commercial activities and high population densities have caused elevated levels of pollution in the city. This study aimed to investigate the spatial distribution of pollutant in Lagos metropolis with a view to revealing the marked spatial/temporal difference in pollutants levels over residential, commercial and industrial land uses. Commercial and industrial land uses revealed higher levels of pollutants than the residential areas. Pearson product moment correlation coefficients revealed strong positive relationship between land use and air quality in the city.

Abstract. Carbon monoxide, CO, and fine atmospheric particulate matter, PM2.5, are analyzed over the Guinean gulf coastal region using the WRF-CHIMERE modeling system and observations during the beginning of the monsoon 2006 (from May to July), corresponding to the Africa Multidisciplinary Monsoon Analysis (AMMA) campaign period. Along the Guinean gulf coast, the contribution of long-range pollution transport to CO or PM2.5 concentrations is important. For PM2.5, desert dust decreases from &#8776;38 % in May to &#8776;5 % in July; biomass burning aerosol from Central Africa increases from &#8776;10 % in May to &#8776;52 % in July. The anthropogenic contribution is &#8776;30 % for CO and &#8776;10 % for PM2.5. When focusing only on anthropogenic pollution, frequent northward transport events from the coast to the Sahel are associated with periods of low wind and no precipitation. In June, anthropogenic PM2.5 and CO concentrations are higher than in May or July over the Guinean coastal region. Over the Sahel, air masses dynamics concentrate pollutants emitted locally and remotely at the coast due to a meridional atmospheric cell. Refining the analysis on the period 8&#8211;15 June, anthropogenic pollutants emitted along the coastline are exported toward the North especially at the beginning of the night (18 UTC to 00 UTC) with the establishment of the nocturnal low level jet. Plumes originating from different cities overlay for some hours at the coast, leading to high pollution level, because of specific disturbed meteorological conditions.
