“…Moreover, the contamination of air with heavy metals in agrarian soil samples in Nigeria has been linked to pesticide use and poor waste disposal systems (Afonne et al, 2022). The presence of trace metals in air-borne particulate matter in Nigerian megacities further underscores the diverse sources of air-borne metals in the country (Gc et al, 2017). The impact of heavy metal air pollution from local metallurgical activities on living organisms, such as albino rats, highlights the potential health effects of air-borne metals in Nigeria (Ugya and Imam, 2018).…”

Heavy metal pollution is a significant environmental concern in Nigeria, posing risks to ecological integrity and public health. This study aims to evaluate the existing policies and regulations addressing heavy metal pollution, assess their effectiveness, and propose recommendations for improvement. The analysis reveals that while Nigeria has established a robust legislative framework, challenges in implementation, enforcement, and funding persist. The impact of reducing heavy metal pollution is influenced by resource constraints, limited capacity, and the need for stronger collaboration between regulatory bodies and industries. Community involvement and education play a crucial role in managing heavy metal pollution, emphasizing the importance of awareness, sustainable practices, and local engagement. Remediation strategies, such as bioremediation and phytoremediation, offer potential solutions. However, gaps in knowledge and research exist, calling for long-term monitoring, ecological impact assessments, and comprehensive health risk assessments. To enhance the effectiveness of current policies, periodic reviews, increased funding, and community-based monitoring programs are recommended. By addressing these gaps and implementing the proposed recommendations, Nigeria can make significant strides towards mitigating heavy metal pollution and achieving environmental sustainability.

The Nigerian city of Lagos experiences severe air pollution as a result of emissions and subsequent atmospheric photochemistry and aerosol chemistry. A year-long study, between August 2020 and July 2021, included measurements of gas-phase and aerosol processes, with surface meteorology at six urban sites. The sites were selected to represent near seacoast conditions, urban sites, and inland locations near agricultural and grassland ecosystems. The observations included continuous concentrations for CO, SO2, NOx, O3, PM2.5, and PM10. Samples were collected and analyzed for speciated volatile organic compounds (VOCs) and particulate chemical composition including inorganic and organic chemical species. The average diel variations in concentrations indicated well-known local photochemistry resulting from the presence of combustion sources, including motor vehicles, petroleum production and use, and open burning. The annual diel characteristics were emission-dependent and were modulated by meteorological variability, including the sea breeze and the seasonal changes associated with monsoons and Harmattan winds. Gases and particulate matter varied daily, consistent with the onset of source activities during the day. Fine particles less than 2.5 μm in diameter (PM2.5) included both primary particles from emission sources and secondary particles produced in the atmosphere by photochemical reactions. Importantly, particle sources included a large component of dust and carbonaceous material. For the latter, there was evidence that particle concentrations were dominated by primary sources, with little secondary material formed in the atmosphere. From complementary measurements, there were occasions when regional chemical processes affected the local conditions, including transportation, industry, commercial activity, and open waste burning.

Wet Deposition of Trace Metals at a Typical Urban Site in Southwestern China: Fluxes, Sources and Contributions to Aquatic Environments

et al. 2017

Abstract:In this study, we quantified the atmospheric wet deposition (AWD) of 13 trace metals (TMs) and estimated their potential effects on the surface water of the Three Gorges Reservoir in China. Precipitation was collected in Wanzhou in southwestern China from March 2015 to February 2016. The concentrations and fluxes of the 13 TMs were in the ranges of 0.16-9.44 µg L −1 and 0.18-10.22 mg m −2 yr −1 , respectively, in the order Al > Zn > Fe > Ba > Pb > Mn > Ti > Cd > Cu > As > V > Ni ≈ Cr. Using principal component analysis, it was found that Al, Ba, Cu, Fe, Mn and Zn were mainly derived from a mixture of soil and road dust, As, Cd, Cr, Pb and Ti primarily originated from the local industries, and Ni and V were related to diesel and gasoline combustion, including both vehicle exhaust emissions and ship emissions from the nearby Yangtze River. The estimated TM inputs to the Three Gorges Reservoir were 11.1, 11.0, 5.7, 5.3, 4.5, 2.7, 2.5, 1.5, 1.0, 0.7, 0.5, 0.2, and 0.2 t yr −1 for Al, Zn, Fe, Ba, Pb, Mn, Ti, Cd, Cu, As, V, Ni and Cr, respectively. The AWD TM fluxes in Wanzhou were lower than those in metropolises and their inputs were limited for surface water of the Three Gorges Reservoir. However, Cd was strongly enriched in precipitation and rainstorms greatly increased the surface water concentrations of Cd and Pb. Therefore, the behavior of Cd and Pb in southwestern mountain areas of China, including emission, transport, transformation, and their ecological effects, should be given more attention in future studies.
