Assessment of Air and Noise Pollution from Industrial Sources in Ibadan, Southwest, Nigeria

Abstract

This study assessed air quality and noise parameters in Oluyole, an industrial zone in Southwest Nigeria. Twenty three sampling points were randomly selected in the industrial and residential areas, while four points control. The assessment was carried out for eight weeks each during rainy and dry seasons. A multi-gas monitor was used to determine sampling CO, SO2, H2S, and Hydrocarbon (HC), while a Personal Data RAM-1200 was used to measure suspended particulate matter (SPM). Noise levels were measured using a sound level meter, while the coordinates of sampling points were taken with a Garmin GPS. Data were subjected to descriptive analysis and one-way analysis of variance (ANOVA) to separate means. Selected air quality parameters varied significantly (p<0.05) for different locations and seasons. Residential and industrial areas showed significant variation in their levels of Noise, SPM and CO. SPM and H2S levels were higher during dry season while Noise, CO and Hydrocarbon levels were higher during the wet season. Levels of Noise, SPM, H2S and CO decreased with increasing distance from the industrial area but the reverse was the case for Hydrocarbon. Hence, there is a need for adoption of cleaner technologies by the industries and enforcement of environmental standards by regulatory agencies.

Prevalence of Pollutant Gases and the Occurrence of Associated Diseases in Asaba Metropolis, Delta State, Nigeria

“…It can be categorized into natural and anthropogenic sources of air pollution. The natural air pollution includes forest fire, volcanic activity such as ash and gases, smoke, organic decay or soil dispersion by wind-blown dust while the anthropogenic sources of air pollution includes human activities as transportation, combustion of fossil fuel and burning of coal for energy demands (Akinsanmi, Olusegun, & Clement, 2018). The contamination of air arises from the natural and anthropogenic activities has been on increase due to urbanization and industrialization.…”

“…The major sources of air pollutants in the environment include vehicular emission which constitute the main source of fine and ultrafine particles and have a serious impact on urban air quality and public health, combustion of fossil fuel, emission released from industrial processes which contributed significantly to high ground level concentration of air pollutants in the surrounding and distant residential areas, construction of road and building activities, as well as mining (Ogunyemi, Oguntoke, & Adeofun, 2019). Approximately 3 billion people worldwide cook with biomass in form of firewood, coal, and residues agricultural activities (Smith, Bruce, Balakrishnan, Adair-Rohani, Balmes, Chafe, Dherani, Hosgood, Mehta, Pope, & Rehfuess, 2014;Edwards, Princevac,Weltman, Ghasemian Arora, & Bond, 2017).…”
