“…By far the most harmful processes for freshwater and marine ecotoxicity have been considered to be the electric installation of the PV system consisting of wiring, switches and other equipment relating to the control system like MPPT microcontrollers on account of copper or aluminium waste release into the ground water, creating health issues like risks for skin and bladder cancers, tumors, kidney problems, hypertension, liver cirrhosis and skin irritation [52]. Arsenic released to the air during electrical installation is the main culprit for human toxicity.…”

One of the standout methods for harnessing renewable energy involves the conversion of solar radiation into electricity using solar cells. The globalization of photovoltaic systems faces challenges, such as balancing environmental, technical, and economic factors. This is addressed through the application of multi-criteria decision-making (MCDM) techniques, which are integral to sustainability. This study aims to determine optimal paths for electricity generation from solar panels, prioritizing minimal environmental impact, maximum efficiency, and the shortest cost payback period (CPP). After evaluating 108 different scenarios based on solar cell type, wiring material, wire sections, and pitch decisions, three solutions were identified. Decision-making tools were employed to select configurations that exhibited the least life cycle emissions, highest grid power injection capability, and the shortest CPP. A notable discovery is the recommendation to use aluminum wires instead of copper wires for electric installation, offering greater benefits. This finding underscores the significance of life cycle assessment in advising sustainable technology choices for solar power plants worldwide, challenging conventional practices like the use of copper wires.

“…Obasi et al (2023) evaluated water quality around mine drainage areas and established that concentrations of Cl À , SO 4 2À , As, Mn, Pb, Cd, Fe, and Hg in some sites exceeded the WHO standard for potable water. Mine drainage and rainfall enrich groundwater with heavy metals, which are harmful to human health (Wang et al, 2022). Mining of lead-zinc (Pb-Zn) sulfide ore deposit coupled with farming are the major occupations of the inhabitants of Ishiagu, Eyingba, and Abakaliki in Ebonyi State.…”

Water sources in mining areas do not retain their natural quality due to the influence of mine drainage. Water quality test was through hydrochemical analysis, speciation modelling and saturation indices. Physical properties were measured insitu using pH/conductivity meter and mercury in glass thermometer. Nitrate, phosphate, sulphate, chlorite, sodium, magnesium, calcium, and total hardness were measured using ion chromatography and titration. Heavy metals were analysed using atomic absorption spectrometer. Mean values of turbidity (0.13 mg/L), lead, (0.01 mg/L) and cadmium (6.40 mg/L) exceeded their permissible values for potable water. Multivariate statistical analysis shows geogenic and anthropogenic sources of chemical species. Chemical speciation shows the cations exist mostly in their soluble and mobile form as free ions. Water quality index shows that few water samples are good for drinking, irrigation and industrial uses, and more are suitable for irrigation only. The method is reproducible by scientists to solve related environmental problems elsewhere.

This study examined the physical, chemical, and heavy metals in groundwater from boreholes and hand‐dug wells at the Lafarge cement factory environment at Sagamu, Ogun State, Nigeria. Water samples were obtained from 20 sampling locations during the wet and dry seasons of 2019. The 17 parameters determined include the pH, temperature, electrical conductivity, total dissolved solids (TDS), total hardness, alkalinity, salinity, chloride, sulfate, phosphate, nitrate, calcium, magnesium, copper, lead, iron, and cadmium. The samples were analyzed using titrimetric and spectrophotometric methods. Correlation analysis was applied as part of the analytical tool in this study. The result indicated low physiochemical concentration of pH, total hardness, sulfate, nitrate, chloride, magnesium, calcium (>1% to 15%), and electrical conductivity (>1000 μS/cm) and fell within the Standard Organization of Nigeria (SON) and World Health Organization (WHO) desirable and maximum permissible limits for potable water during the wet and dry seasons. However, phosphate was above the standard limit for portable water of 6.5 mg/L in all sampling locations, whereas the total alkalinity was above the WHO standard limit (200 mg/L) in 12 locations in the wet seasons and a location in the dry season. Salinity was also above standards in one and four locations in the wet and dry seasons, respectively. Lead and cadmium were not detected in most locations, whereas iron, lead, cadmium, and copper were above standard limits in some locations. A significant relationship exists between the heavy metals and some of the physiochemical parameters at p ≥ .05 and p ≥ .01. The polluted water in most locations is capable of resulting in an adverse health hazard. Thus, this study explains the effect of physicochemical and heavy metals on water management at Sagamu and is important for water resource planning.
