“…An examination of the heavy metal concentrations in the soils from the study region brings forward several comparisons to findings from other regions. The soils in schools of this region were reported to hold higher Cu, Ni, and Zn concentrations compared to those in Benin City, Nigeria, as noted by Biose et al [38]. A comparative analysis with soils from Nigeria's Ijero region reveals that the extraction districts of the region under study show greater Cd, Cr, and Zn concentrations [39].…”

An investigation was conducted to determine potential threats of heavy metal contaminants in soil samples from Ado-Ekiti, Southwest Nigeria, across distinct land-use zones. Five soil specimens were systematically gathered from each of the following locales, representing heightened anthropogenic activities: marketplaces, motor parks, schools, mining sites, and residential regions. Using an atomic absorption spectrometer, the soil samples' chemical compositions were scrutinized with a focus on elements such as As, Cu, Cd, Cr, Co, Ni, Pb, Zn, and Fe. Indices, including the geo-accumulation (Igeo), contamination factor (CF), and pollution load index (PLI), were employed for contamination assessment of metals in the soils. Furthermore, Ecological and Human Health Risk Assessments (HHRA), following the United States Environmental Protection Agency (USEPA) guidelines, were carried out to establish the probability of detrimental impacts of heavy metals in the soils on human and environmental health. Mean concentrations (mg/kg) across all zones for As,

“…Similarly, Sarkar et al [ 39 ] reported higher amount of heavy metal in shrimps from some farms in Bangladesh. Reports from studies by Biose et al [ 40 ] and Edogbo et al [ 35 ] also showed higher quantities of heavy metals in vegetables, tubers and soil in different parts of Nigeria. The above therefore highlights the need for a holistic approach to ensure the protection of people from both direct and indirect exposure to heavy metals.…”

Introduction The burden of cardiovascular disease (CVD) is huge due to its associated morbidity, mortality and adverse socio-economic impact. Environmental pollution as a risk factor contributes significantly to the burden of CVD, especially in the low and middle income countries. One of the effective strategies to reduce CVD burden is to prevent or detect cardiovascular risk factors early in at-risk population. This study determined some cardiovascular risk factors, kidney function, and their association with heavy metals among automobile mechanics. Method This was a cross-sectional study involving 162 automobile mechanics and 81 age and sex matched controls. Serum levels of lead, cadmium and some cardiovascular risks were assessed and compared in the two groups. Associations between serum lead, cadmium and some cardiovascular risks were determined using correlation analysis. P value of <0.05 was taken as significant. Results The mean ages of the automobile mechanics and controls were 47.27±9.99 years and 48.94±10.34 years, respectively. The prevalence of elevated serum cadmium was significantly higher in the automobile mechanics (25.9% vs 7.9%; p = <0.001). The significant cardiovascular risk factors in the automobile mechanics vs controls were elevated total cholesterol (32.1% vs 18.5%; p = 0.017), hyperuricemia (20.4% vs 1.2%; p = <0.001), elevated blood glucose (16.0% vs 4.9% p = 0.013); and alcohol use (55.1% vs 30.0%; p = 0.001). Among the automobile mechanics, there were significant positive correlations between serum cadmium, atherogenic index of plasma (AIP) (p = 0.024; r = 0.382) and triglyceride (p = 0.020; r = 0.391). Significant positive correlation was found between serum lead and neutrophil gelatinase associated lipocalin (NGAL) (p = <0.001; r = 0.329). There were significant positive correlation between serum cadmium level, AIP (p = 0.016; r = 0.373) and TG (p = 0.004; r = 0.439); between serum lead and NGAL in all the study participants (p = 0.005; r = 0.206). Conclusion Automobile mechanics have notable exposure to heavy metals and a higher prevalence of some cardiovascular risk factors. Health education and sensitisation as well as policies that would regulate exposure of persons to heavy metals should be implemented in Nigeria.

“…Heavy metals are known pollutants which are toxic and persist in the environment (Pekey, 2006;Nemati et al, 2011;Enegide & Chukwuma, 2008;Nwawuike & Ishiga, 2018) and a source of poor ecological quality (Defew et al, 2005). Several heavy metals such as cadmium (Cd), lead (Pb), arsenic (As), chromium (Cr), zinc (Zn), copper (Cu), mercury (Hg) and nickel (Ni) are among the most hazardous and environmentally relevant heavy metals associated with crude oil pollution (Bamgbose et al, 2012). These metals are not easily degraded (Yan et al, 2020;Guijarro, 2021;Raffa et al, 2021), transferred through trophic processes in both terrestrial and aquatic environments and thus possess substantial ecotoxicological risks (Proshad et al, 2018;Ali et al, 2019;Proshad et al, 2019).…”

The study assessed the impact of crude oil on farmland soils in Ohaji Egbema. Farmlands used for this study are farms that were indirectly impacted through overland flow and acid rain. A total of 42 farmland soil samples were used for this study. The farmland soil samples were collected at a depth range of 0 - 10 cm using a hand trowel through random sampling. The samples were air dried for 72 hours before laboratory analysis for arsenic (As), nickel (Ni), chromium (Cr), cadmium (Cd) and lead (Pb). The results obtained show that heavy metals in farmland soils at different locations in Ohaji/Egbema varied in both concentration and trend. The observed trends at different locations are: Cd>As>Ni>Cr>Pb for Mmahu, Abaezi, Abacheke and Awarra while for Assa and Obitti, it is Cd>Ni>As>Cr>Pb. To establish the extent the farmland soils were polluted, contamination factor (CF), degree of contamination (Cd) and geoaccumulation index (Igeo) were applied. Results of the Cf showed that Ni, Cr and Pb had low contamination, As had moderate contamination while Cd had high contamination in the farmland soils with a range of 155.15 - 206.87 and Cd of 1242.72. The Igeo for Cd ranged from 31.13 to 41.52, an indication of extreme contamination. The associated potential ecological risks were assessed using potential contamination index (PCI), ecological risk factor (Eri) and ecological risk index (RI). It was found that Cd had PCI ranging from 155.22 - 198.51, Eri range of 4654.44 - 6206.11 and RI of 37311.56. This indicates that the farmland soils of Ohaji/Egbema are highly contaminated with Cd and exposed to severe ecological risk.
