Gas flaring operations as experienced in the Niger Delta region (NDR) of Nigeria are characterized with release gases, particulates, noise and heat that have adversely affected both human environment. The purpose this paper was to conduct an inventory pollutants (NOx, SOx, CO, NMVOC, PM2.5, organic carbon (OC)) released over half a century order assess environmental health risk region. Data on volumes gas flared country emission factors sourced from literature were used carrying out 1965...

A detailed method used for assessing and mapping noise pollution levels in Ota metropolis, Nigeria using ArcGIS 10.5 Software is presented this paper. Noise readings were measured at a time interval of 30 min each site considered precision grade sound level meter. The map developed was based on the computed values average equivalent (LAeq) selected locations. Results study show that weighted (LAeq), background (L10) peak (L90) vary with location period day due to traffic characteristics...

Sub-Sahara Africa is renowned for poor electricity supply with Nigeria's case being critical. Generator sets, which have been adopted as an alternative and reliable source of power in Nigeria, are linked to emission footprints detrimental the environment human health. The dearth literature open domain on concentrations pollutants potential health risk related use gasoline-fueled generators prompted this study. Concentrations CO2, CO particulate matter (PM2.5) emitted from selected randomly...

Emissions from fossil fuel combustion are of global concern due to their negative effects on public health and environment. This paper is an inventory the greenhouse gases (GHGs) released into environment through consumption fuels (gasoline diesel) in Nigeria 1980 2014. The data for period view were sourced bulletins by National Petroleum Corporation, (NNPC) utilized GHGs estimation based default emission factors (69300 kg/TJ (CO2; gasoline), 74100 diesel), 18 (CH4; 3.85 1.9 (N2O; gasoline)...

Inventories of the greenhouse gases (GHGs) emitted into atmosphere through gas flaring are scarce; hence, need for this study. Formulae reported by Association Petroleum Institute were used estimating GHGs based on data (1965 to 2013) sourced from national agency information production and in Nigeria. Analytica® (4.5) was employed estimate uncertainty associated with emission inventory using a Tier 2 method. In study, 1.87 × 109 tons CO2, 1.09 107 CH4 37.41 N2O estimated have been released...
