“…Earlier assessment of herbal preparations from the study area [15], suggests that there is possibility of heavy metal intoxication of the inhabitants in addition to attenuation of the phyto-potency of the preparations by the heavy metals. This is supported by earlier fi ndings on the concentrations of these heavy metals in the soil, water and foods from this area and its environs [16][17][18].…”

Background: Human exposure to xenobiotics, especially priority heavy metals (lead, cadmium, arsenic, mercury and chromium), is unavoidable because of their involvement in industrial applications, accumulation in the environment over time and non-biodegradability. Unfortunately, they induce unprecedented biochemical and pathological changes on those exposed to them, causing oxidative damages and organ toxicities. Aim: This study investigated the frequencies of priority heavy metals and their impact on some micronutrient elements (copper, iron, zinc) in the blood of inhabitants of a lead-zinc mining community in southeastern Nigeria.

“…factors) between rock weathering and precipitation segments (Fig. 8) signified chemical dilution of rock minerals by influence of precipitation (Okogbue and Ukpai 2013). It means that percolation of precipitation (rain) water resulted in the chemical weathering via rock dissolutions (Fig.…”

“…It is suspected that at cooking temperature, diffusion space for the dissolved Fe decreases; as such, the ion diffuses into the food stuff. Okogbue and Ukpai (2013) earlier reported metal poisoning among the people of Abakaliki Province and traced it to mine effluent that released heavy metal plumes to the water resources. It is thus safe to establish that metals, particularly those analysed like Fe, Mn, Zn, Co, Pb and Cr, are exposed to biota of the region, by either intake of the affected water supply or consumption of food poisoned by the metals.…”

“…The transfer of chemicals (dissolved solutes or ions) exposes biodiversity to bioavailability of the ions; hence, the purpose of this study was to evaluate the extent of ionic concentrations, mode of chemical movement and the ecological risk assessment with respect to the national economy. Tijani et al (2018) reported mineralization of water resources in the entire lower Benue Trough, mainly due salt and ore deposits, even as Okogbue and Ukpai (2013) and Obiora et al (2016) had earlier related such mineralization at Abakaliki axis of the trough to point source loading from active and derelict mine sites. But then, due to the dispersed calcareous sediments at the eastern flank of Abakaliki Anticlinorium, the present study traced the pollution units to both continuous non-points (or dispersed) loading sources and the point sources.…”

Eco-hydrology and the effects on the national economy: case of the eastern region of Abakaliki Anticlinorium, Southeastern Nigeria

The area was mineralized, yet it is an agricultural settlement. Histories of water hardness and local migration of connate (saline) water exist across the region. This study investigated effects of these geogenic circumstances on the economy of the region and Nigeria. Geophysical and geochemical analyses were carried out for delineation of hydrological structures relevant to groundwater movement and pollution status, respectively. Results revealed silty-sandy shale sandwiched between 60 and 100 Ω-m at the fourth geoelectric layer. This layer marks depths to water table from 7.0 to 12.0 m and formed aquitard as medium of regional stance for groundwater percolation. The aquitards confined localized resistivity anomalies of ≤ 60 Ω-m and was interpreted as various aquifers. Isolated peaks of hydraulic head up to 85 m around northwestern and southeastern ends of NW-SE-trending local water divide indicated areas of water table crops where conjunctive hydrological interaction exists between surface water and groundwater resources; each flushes dissolved elements from the calcareous sediments into the water resources. Consequently, configurations of pH, total dissolved solutes (TDS), electrical conductivity (EC) and total hardness ranged as: 6.97-7.96, 20-1399 mg/l, 30-2100 μs/cm and 8-160 mg/l, respectively. Localized concentrations of calcium, sodium, bicarbonate, sulphate, chloride, iron, manganese, zinc, lead, chromium and cobalt in mg/l ranged to pollution or alert levels as follows

“…Negligible eigen-values were observed in C3, C4 and C5, for which information relating to any geological process was hidden (Ukpai & Okogbue, 2017). A factor is significant if the eigen-value is greater than/or equal to 0.5 (Okogbue & Ukpai, 2013). All except pH and Fe are eigen-values in C1; while in C2, all except Fe, pH and Mg are not eigen-values, whereas NO 3 is the only significant variable in C3.…”

Socio-economic influence of hydrogeology in regions adjoining coal bearing formation: Water policy in Anambra Basin

et al. 2021

The Coal Province lies within the central portion of Anambra Basin and along the axis of regional water resources catchment of Southeastern Nigeria. Although this area includes a prolific aquifer, the high cost of development and treatment of the groundwater degraded by AMD has created water scarcity problems against water policy initiatives. Social and economic impacts were investigated, even as policy measures for rehabilitation purposes through water resource management were highlighted. Several geoscientific methods were integrated for the investigations. Mean resistivity up to 30 Ω-m relatively at shallow depths indicated aquitards of Enugu/Mamu Formations, whereas the aquifer reflected resistivity ≤1,000 Ω-m at depths of ≥180 m across Ajali Sandstone. Alkaline-rich seepage flushed Fe-rich AMD at aquifer-aquitards interfaces adjoining the river catchment area. The AMD-induced oxidation process produced noxious Ca-Mg-Na-HCO3-SO4-Cl facie. These results were correlated with policy related questionnaires. Plans for water security were proposed, mainly to channel groundwater directly from the regional aquifer, or the chemically degraded seeped water from the fluvial system, into constructor water reservoir (treatment) columns prior to distribution to the town-water supply. Such water resource development is cost effective; and with management policies regulated by relevant decision-making agencies, sustainable supply is assured.
