“…As a trace mineral element, Cu exists naturally in plants where it participates in most decisive vital mechanisms. Cu is considered essential in the regulation of some biological processes and the maintenance of vascular and skeletal integrity (Ibe et al 2019c). Prolonged intake of Cu contaminated water could result in haematuria, gastrointestinal bleeding, intravascular haemolysis, hepatocellular toxicity, oliguria, and acute renal failure (Agarwal et al 1993;Ashish et al 2013;Hefnawy and Elkhaiat 2015;WHO 2004b).…”

The study investigated groundwater sources within reclaimed municipal waste dumpsites around Akachi road in Owerri, Southeastern Nigeria. The research evaluated the pollution and risk inherent in the consumption of groundwater in the vicinity of the reclaimed waste dumpsite using standard procedures. Results showed acidic pH values for some groundwater samples within the reclaimed waste dumpsite. Elevated nitrate (NO3−), aluminium (Al) and chromium (Cr) concentrations above the World Health Organization (WHO) limits for drinking water samples were recorded in some of the groundwater samples from the study area. The observed strong positive correlations between the metallic contaminants indicated that the distribution of the pollutants has a strong relationship with organic contaminants in the reclaimed waste dumpsite. Low contamination factor was exhibited by all metals for the individual samples except for Cr in sample A and Al in sample A and D. The pollution load index for all the samples was low, except for sample C with a pollution load index of unity. Elevated hazard quotient > 1 and hazard index > 1 were observed for both adults and children due to high Cr levels. The chronic daily intake risk assessment revealed values < 1, while carcinogenic risk values greater than 10−6 and 10−4 were observed for the samples suggesting potential health risk for children and adults. The water quality index of samples from the reclaimed waste dumpsite calls for concern due to elevated levels of Al and Cr. These findings, therefore, suggest the need to treat the groundwater from the reclaimed dumpsite before consumption to avert serious health risks. Finally, waste dumpsites should be remediated or allow to undergo natural remediation before reclamation, erecting residential structures, and sinking of boreholes for water supply within such areas.

“…Anthropogenic pollution and the distribution of organic and heavy metal pollutants have been reported in major publications (Wee, Moll and Dirks, 2000;Ossai, 2014;Thompson et al, 2019). Similarly, heavy metals released during metal extraction processes, industrial activities, hazardous electronic wastes, municipal wastes, and agrochemical leachates, as well as oil spillage, can pollute water bodies (Ibe et al, 2018;Ibe et al, 2019;Boateng et al, 2019). As a result, there is an urgent need to regularly monitor the quality of groundwater supplies, particularly in contaminated areas Akakuru et al 2021a;Agidi et al 2022).…”

Non-carcinogenic health risk assessment and predicting of organic and heavy metal pollution of groundwater around Osisioma, Nigeria, using Artificial Neural Networks and Multi-Linear Modeling Principles has been done. 30 groundwater samples were collected systematically and analyzed for organic and heavy metal pollutants. The results of the analysis showed that the heavy metals and organic pollutants within the study area contributed to the pollution of groundwater resources in the locality. However, copper, ethylbenzene, xylene and toluene were within the recommended standard, whereas arsenic, iron, chromium, lead, and benzene were above the recommended standard for drinking water. Correlation matrix and principal component analysis assessment indicated weak correlation and that organic pollutants were major contributors to the loadings. The Contamination factor, Pollution load index, Metal pollution index, Geoaccumulation index, Potential ecological risk index, Elemental Contamination Index, and overall Metal Contamination Index showed no significant pollution, whereas the Heavy Metal Evaluation Index, Pollution Index of Groundwater results showed worrisome impact of the anthropogenic activities on the groundwater quality. Health risk assessment showed that children are more at risk than adults as it related to taking polluted water. MLR models performed better than the ANN. Seven (7) mathematical models were generated for the prediction of pollution indices. Based on the results, this study recommends regular monitoring of groundwater resources and the integration of ANN and MLR modeling approaches for the prediction of pollution indices.

“…The presence of these environmental pollutants most often result in the buildup of heavy metals in the soil which may finally find their way into the plant tissues [ 7 ]. Also, the migration of the spent oil and percolation of leachates from the materials contained in the oil poses serious threats to the surface and groundwater quality [ 8 – 10 ].…”

“…Several earlier reports revealed that human exposure to elevated concentration of heavy metals particularly children may result in several illnesses such as kidney and liver damage, paralysis, convulsion, depression, and pneumonia [ 14 – 16 ]. Other effects of heavy metals on human health have been reported in several key publications [ 10 , 16 – 18 ].…”

“…Therefore, there is an urgent need to regularly assess the impact of automobile mechanic workshops on the environment. The need for monitoring and assessment has become necessary as there could be severe contamination of the surrounding air, surface water, groundwater, soil, and river sediments [ 10 , 22 – 24 ]. Environmental contamination may result from heavy metals, such as Cd, Cu, and Pb, as well as organic contaminants, like PAHs, polychlorinated biphenyls (PCBs), and poly-brominated diphenyl ethers (PBDEs) [ 25 , 26 ].…”

Geo-environmental assessment of activities of auto-mechanics at Alaoji Aba and Elekahia Port Harcourt, both in the Niger Delta region, Southern Nigeria were carried out with the main objective of determining the extent of soil contamination arising from anthropogenic activities within mechanic villages (MVs). Geochemical analysis of soil samples from the study area revealed that the concentrations of the trace metals ranged from <1 mg/kg for chromium (Cr) to 1,925 mg/kg for the lead (Pb). Soil analysis for polycyclic aromatic hydrocarbon (PAH) and total petroleum hydrocarbon (TPH) across the area revealed concentrations ranging from <0.02 to 1.80 mg/Kg and from <1.00 to 38,327 mg/kg respectively. Elevated levels of the heavy metals and TPH were observed at MV in Alaoji Aba when compared to MV in Elekahia Port Harcourt, and the control sites. These could be attributed to contamination due to the presence of these auto-mechanics in the area for over thirty years. The concentration of Pb and Cd recorded in some sample points were above USEPA (United State Environmental Protection Agency) and the National Environmental Standards and Regulations Enforcement Agency (NESREA) permissible limits. Results of PAH analysis showed the presence of naphthalene, phenanthrene, pyrene, fluorene, benzo(a)anthracene, acenaphthene, methylnaphthalene. Risk assessment analysis showed significant geo-accumulation values for Cd and Pb indicating heavy contamination. The monomial risk factor of the heavy metals in the MVs are in the order Cd >Pb>Cr, while potential ecological risk index analysis showed values indicating very high risk, considerable risk and a moderate risk to the area under study as well as the surrounding environment. These results suggest that the soils from the MVs which represent the mechanic workshops at Alaoji Aba and Elekahia Port Harcourt are considered to be of pollution concern due to elevated Pb and Cd levels. Hence, there is a serious need to regularly monitor the activities of auto-mechanics in the study area.
