“…Below, we will use the term 'fuel gas' to refer to natural gas that is flared. The quantity of contaminants expelled at this stage of processing depends on the technology employed, quantity of crude oil processed, flare geometry and design, prevailing meteorological conditions and the composition of the flared gas (E & P Forum, 1994;Ismail and Umukoro, 2014;Johnson and Coderre, 2011;Obanijesu et al, 2009;Ouf et al, 2008;Sonibare and Akeredolu, 2004;Talebi et al, 2014).…”

“…At the local scale, ground-level measurements within one kilometre downwind of the flaring sites have indicated an elevated concentration of particulate and gaseous pollutants (Edwards et al, 2013;Obanijesu et al, 2009;Sonibare et al, 2010). Likewise, on a regional scale, flight campaign during ACCESS (Arctic Climate Change Economy and Society) around oil and gas installations in Heidrun, Norway reported elevated concentrations of NO, SO 2 and CO in the lower troposphere (Roiger et al, 2015).…”

“…In-situ ground measurements of air pollutants around typical oil and gas facilities where varying degrees of gas flaring take place have been undertaken in the US (Edwards et al, 2013;Edwards et al, 2014;Johansson et al, 2014), Mexico (Villasenor et al, 2003, Norway (Roiger et al, 2015) and, Nigeria (Ana et al, 2012;Nwaichi and Uzazobona, 2011;Obanijesu et al, 2009;Sonibare et al, 2010). Continuous noise levels higher than the WHO limit of 70 dB were also observed around some gas flaring sites in Nigeria (Abdulkareem and Odigure, 2006;Avwiri and Nte, 2004).…”

Gas flaring is a prominent source of VOCs, CO, CO2, SO2, PAH, NOX and soot (black carbon), all of which are important pollutants which interact, directly and indirectly, in the Earth's climatic processes. Globally, over 130 billion cubic metres of gas are flared annually. We review the contribution of gas flaring to air pollution on local, regional and global scales, with special emphasis on black carbon (BC, "soot"). The temporal and spatial characteristics of gas flaring distinguishes it from mobile combustion sources (transport), while the open-flame nature of gas flaring distinguishes it from industrial point-sources; the high temperature, flame control, and spatial compactness distinguishes gas flaring from both biomass burning and domestic fuel-use. All of these distinguishing factors influence the quantity and characteristics of BC production from gas flaring, so that it is important to consider this source separately in emissions inventories and environmental field studies. Estimate of the yield of pollutants from gas flaring have, to date, paid little or no attention to the emission of BC with the assumption often being made that flaring produces a smokeless flame. In gas flares, soot yield is known to depend on a number of factors, and there is a need to develop emission estimates and modelling frameworks that take these factors into consideration. Hence, emission inventories, especially of the soot yield from gas flaring should give adequate consideration to the variation of fuel gas composition, and to combustion characteristics, which are strong determinants of the nature and quantity of pollutants emitted. The buoyant nature of gas flaring plume, often at temperatures in the range of 2000 K, coupled with the height of the stack enables some of the pollutants to escape further into the free troposphere aiding their long-range transport, which is often not well-captured by model studies.

“…When AQI is in the range of: with the exploited crude oil is either flared or vented into the atmosphere (Obanijesu et al, 2009). Nigeria is presently the leading gas flaring country in the world, with around 24 billion cubic meters of gas flared in 2004 for instance, or 45 percent of its total gas production (World Bank, 2008) and all these take place in the Niger Delta.…”

“…These pollutants are not usually confined to the emission point sources. For example, pollutants from flared gases have been observed with concentrations beyond recommended exposure limits in residential communities within 60 m range of the emission source (Obanijesu et al [16]). Existing Environmental Impact Assessment (EIA) legislation and other pollution control policies have been disproportionately focussed on regulating the oil and gas industries (Ogunba [11]).…”

Since 1988 the Nigerian Government has introduced environmental legislation aimed at reducing the atmospheric impact of various sources of pollution. Emphasis has often been placed on mitigating pollution from the oil and gas industry. However, various studies indicate significant ambient air pollution from other sources due to vehicular traffic growth in urban areas, increased reliance on petrol and diesel fuelled generators for electricity supply in homes and other public facilities, uncontrolled open incineration of waste and major thermal power stations within the city limits. In this paper, we make the case for the establishment of risk-based air quality management approach based on monitoring, modelling and assessment of these other sources. We outline four important elements that should be considered in order to achieve this recommended approach. These elements are conceptualised within the existing institutional, organisational structures and capacity in Nigeria.
