In a significant study published in the ABUAD Journal of Engineering Research and Development, researchers have unveiled alarming insights into the air pollution levels emanating from construction activities on Lagos Island, Nigeria. The research, led by Temiloluwa Oluwapelumi Susan Owolabi from the Department of Architecture at Caleb University, highlights the pressing need for robust environmental assessments in urban construction practices.
As Lagos continues its rapid urbanization, construction sites are becoming hotspots for air pollutants, with potentially serious implications for public health and environmental quality. Owolabi’s study meticulously measured pollutants such as carbon monoxide (CO), nitrogen oxides (NO and NO₂), ozone (O₃), and particulate matter (PM₂.₅ and PM₁₀) using advanced instrumentation like the Earth Sense Zephyr and the ARA n-FRM Sampler. The findings revealed that construction activities, vehicle emissions, and industrial sources significantly influenced air quality, with CO and NO levels peaking during certain months.
“The construction sector must recognize its role in contributing to air pollution,” Owolabi stated. “Our findings underscore the urgency of implementing effective dust control measures and adhering to stringent regulations to protect public health.”
The research identified a concerning trend: particulate matter concentrations soared during the dry season, attributed to construction dust and the absence of rain, indicating that weather conditions play a crucial role in air quality. This seasonal variability poses challenges for construction firms, which must adapt their practices to mitigate dust emissions, particularly during peak construction periods.
The implications for the construction industry are profound. As awareness of environmental issues grows, clients and stakeholders are increasingly prioritizing sustainable practices. Companies that proactively address air quality concerns may find themselves at a competitive advantage, attracting environmentally conscious clients and avoiding potential regulatory penalties.
Owolabi emphasized the need for a shift in mindset, saying, “Promoting sustainable construction practices and enhancing public awareness about air pollution can lead to healthier urban environments.” This perspective aligns with a broader trend in the construction sector, where sustainability is no longer just an option but a necessity.
As cities like Lagos grapple with the dual pressures of development and environmental stewardship, the research serves as a clarion call for the construction industry to innovate and adapt. By integrating sustainable practices and investing in cleaner technologies, the sector can not only improve air quality but also enhance its commercial viability in an increasingly eco-conscious market.
This study is a pivotal step towards understanding the dynamics of air pollution in construction, and it lays the groundwork for future research and policy formulation. For more information about the lead author’s work, visit Caleb University.
