“…The mean concentration values recorded in this work was slightly lower or at the same level or slightly higher than the required maximum limit for potable water by the WHO (2011) and USEPA (2005) of 0.005mg/L for cadmium in potable water. The level of cadmium obtained in this work was at the same range or far lower than that which was reported by Musa et al, (2007) which was in the range of < 0.001 to 0.28mg/L in boreholes and well water in Zaria, Nigeria and was at the same range or higher than that obtained by Obiri (2007) which was 0.002ppm in Dumasi, Wassa West, Ghana, and was also at the same range or lower than than that recorded by Nwoke and Edori (2020) in the boreholes of Ikono which ranged from not detected to 0.47±0.22mg/L. Contact or intake of inorganic chemicals such as cadmium in the environment results in poisoning and health risk, due to the toxicity of cadmium and its effect due to accumulation (Ferrer et al, 2000;Klaassen, 2000).…”

The concentration of six chemical species Pb, Cd, As, nitrates, fluorides and sulphates in the groundwater (borehole) samples were investigated in four boreholes sited close to a dumpsite in Rumuolumeni, Port Harcourt, Rivers State, Nigeria. Nitrates, fluorides and sulphates were analyzed using standard conventional methods while the heavy metals were determined and analyzed with Atomic Absorption Spectrophotometer. The mean values obtained for the different chemical species within the months of investigation for the stations were in the range: lead; 0.012±0.001-0.015±0.000mg/L, with an average of 0.013±0.001mg/L within the months, Cd; 0.004±0.002-0.005±0.001mg/L, with an average of 0.005±0.001mg/L within the months, As; 0.002±0.001-0.003±0.002mg/L, with an average of 0.003±0.001mg/L within the months, nitrates; 0.413±0.172-0.730±0.691mg/L, with an average of 0.511±0.139mg/L within the months, fluorides; 0.004±0.001-0.006±0.001mg/L, with an average of 0.005±0.001mg/L within the months and sulphates; 0.197±0.046-0.338±0.072mg/L, with an average of 0.290±0.055mg/L within the months. These values obtained for the different chemical species showed that the boreholes sited near the dumpsite were still at the level that will not pose any health risk to the user, for their concentrations were still within limits allowed by WHO and USEPA. Even though the government and its agencies should regulate the mode of dumping of refuse and also the siting of boreholes so that the groundwater will not be polluted.

“…The loss of vegetation cover and landscapes is unprecedented and consequential evidence of mining. For example, mining has destroyed over 1,000 acres of agricultural land in the Baryte mines [19]. In addition, the area's cultivable land for growing food crops has been polluted and degraded, with no strategic restoration and reclamation plans in the district.…”

“…In addition, the oil pipeline construction in Niger has fragmented natural vegetation with the death, of many local trees and the destruction of agroforests and gardens. Mining of baryte in the Azara district of Nasarawa state has affected economic trees such as mango (Mangifera indica), dorawa (Parkia biglobosa), and kirya (Prosopis africana), as well as grass species, including spear grasses [19].…”

Mining activities have led to the depletion of over 577.15 km² of forest area in the West African Sahel zone. These have destroyed the habitats of mammals, including elephants and giraffes, as well as economic trees and grass species, and polluted ground and surface water. In addition, mining activities are responsible for degrading more than 1,000 acres of farmland. Even though mining is destroying the environment, it has accounted for exports of €211,468,13, €247,034,485 and €275,720,817 in Burkina Faso, Niger, and Mali, respectively, between 2014 and 2015. It is also a lever of sustainable environmental management, as in Senegal, by providing mining social funds for mining communities and employing over 450,000 people in Niger. Furthermore, mining companies promote land restoration activities in the West African Sahel, such as China National Petroleum Corporation (CNPC) promoting tree plantations in Niger. Nevertheless, the mining in the region will continue to serve as the breeding ground for criminal gangs and terrorist groups unless a radical approach stabilises the insecurity. The degradation of farmlands and forest reserves or protected areas requires re-evaluation and full enforcement of the existing laws and regulations to achieve sustainable mining for the needed development in the West African Sahel region.

“…(Figure 2) As compared to other methods FAAS is relatively inexpensive and easy to operate but has some drawbacks that limit the use of flame atomic absorption spectroscopy). [17][18][19] • Large volumes of aqueous sample required in introduction system. • The Contact time between metal ions and gaseous molecules is relatively high results in burning velocities of the gases, helps in estimation of higher amount of ion metals.…”

In human body building as well as in plants Metal ions play a vital role in vital functioning such as in various food chain reactions. Due to increase in industrialization everyday various industrial wastes contaminated with metal ions and metalloids. Several enzymes need them for their catalytic action, and their absence can cause a number of illnesses in humans. When this metal ions concentration level increases above the certain limits, it is harmful to human, animals, plant as well as aqua system. Because various essential biological processes in humans depend on metal ions, their absence or scarcity may result in diseases. In pharmaceutical sectors various transition metals are used as catalyst to improve kinetics of reaction. Therefore, it is necessary to determine concentration of metals ions whether it is present in within the limits, otherwise excess of its concentration may leads to toxicity in body. Also, the advisory body has made some regulatory guidelines to monitor and control levels of metals ions in food, environment and medicines. Hence more precise, accurate, economically acceptable, sensible and selective method are required to detect metal ions concentration in pharmaceutical, environmental, agrochemical and aquatic samples as well as in body tissues/fluids is also essential. Hence in our review we try to sum up various metal ion detection techniques, there mechanism and principle behind detection of heavy metal ion detection and instrumentation. The given methods are more sensitive at very low detection limits of up to pictogram level, accurate and more precise levels detection has been achieved.
