Compendious evaluation of groundwater in parts of Asaba, Nigeria for agricultural sustainability

Hydrogeochemical characterization and quality assessment of groundwater based on water quality index in urban area in SE Nigeria.

“…PLI is an e cient method for determining the toxicity of heavy metals in representative samples (Akakuru, et al, 2021b;Yang et al, 2011). The most common PLI categories are unpolluted (PLI1), unhealthy (PLI> 2), severely polluted (2PLI> 3), and very heavily polluted (3> PLI).…”

Application of artificial neural network and multi-linear regression techniques in groundwater quality and health risk assessment around Egbema, Southeastern Nigeria

“…Then again, the nature of groundwater generally relies upon the substance creation that is available and the focus levels of these synthetic boundaries are significantly gotten from the anthropogenic and land exercises in a specific district or region Yahaya et al, 2021). Many elements control the groundwater quality; they incorporate geology, precipitation, mineral structure and dissolvability, oxidization, ionic trade, poor sterile circumstances, poor and uncontrolled composts, and pesticide application with minimal comprehension of substance cosmetics soils (Akakuru et al, 2017;Sakram and Adimalla, 2018).Regardless of the overflow of groundwater, it is as yet unusable when its quality is significantly debased by substance defilements with expanding human populace, industrialization, urbanization and the resulting increment for the interest of water for both homegrown and modern purposes, the orderly expansion in the ramifications of dirtied water on man and the climate have been severally contemplated (Egbueri, 2019;Barzegar et al, 2019;Akakuru et al, 2021b;Eyankware et al, 2021a,c;Akakuru et al, 2022).It is important to note that the concentration of heavy metals in groundwater resources has greatly increased due to anthropogenic activities and this poses threat worldwide. In the past 5-6 decades, there has been a high increase in the rate at which humans are exposed to heavy metals and this has been attributed to an exponential increase in heavy metals released from exploration, exploitation, mining, industrial, agricultural processes, technological advancement and her increase in the human population (Opara et al 2021).…”

“…Yang et al (2019) has reported that two incidences among the top ten (10) global environmental disasters are attributed to contamination by heavy metals. Consequently, the release of large volumes of untreated effluents which contain a high concentration of heavy metals by industries into soils, surface and groundwater resources has further worsened the problem (Tziritiset al, 2017;Akakuru et al 2021b). The toxic impacts of heavy metals often result from the intake of heavy metals, contaminated food, and water absorption through dermal contact with humans and inhalation of contaminated air.…”

Potential health risk and level of heavy metal in groundwater in the highly-dense area of Akure, Southwestern Nigeria

“…In the eld of assessing water quality, the heavy metal index and health risk assessment have grown in popularity during the past few years. They are viewed as a forecasting tool and have been used extensively across many industries (Akakuru et al 2021b;Eyankware and Akakuru, 2022;Akakuru, et al, 2022). However, there hasn't been much investigation on the human health risks connected to occupational (i.e., exposure to hazardous chemicals as a result of one's work schedule) exposure to toxic metals from anthropogenic activities in Akure, Ondo State, SW Nigeria.…”

“…, 2017). According to Bortey-Sam et al (2015) and Barzegar et al (2015), the USEPA (1989) classi ed non-carcinogenic risk as follows: (2015).Contamination factor (CF)The CF was calculated using the Hakanson (1980) formula CF = \frac{{C}_{n}}{{B}_{n}}(12) Where: Cn is the metal concentration, Bn is the background/target value (Egbueri 2020;Akakuru et al, 2021b; Yahaya et al, 2021).…”
