Health Risk Assessment on Heavy Metals Ingestion through Groundwater Drinking Pathway for Residents in an Oil and Gas Producing Area of Rivers State, Nigeria

Abstract

In the study, health risk assessment on heavy metals ingestion was presented through the groundwater drinking pathway for residents in an oil and gas producing area of Rivers State, Nigeria. The level of the ground water pollution was examined, the quality of the borehole and the well water was assessed and the quality of the ground water pathway for the resident in the oil and gas producing area was determined and compared with the national and international standards for the drinking water. This study adopted both the field and laboratory experimental analysis of physical and chemical parameters. Water samples were analyzed for Physico-chemical parameters following acceptable methods to determine the compliance, and the results were analyzed according to drinking water guidelines. Interestingly, the results show that the ground water contained high amounts of turbidity (21.5 NTU, 23.00 NTU and 19.0 NTU in the borehole water and well water), iron (5.3 mg/L in the ground water and 6.98 mg/L in the borehole water) and pHs of all water samples were acidic in the study area. These results show that ground waters including the borehole and the well waters of the study area had acquired reasonable levels of pollution. Whereas, other values were found to be lower or above and corHow to cite this paper: Olalekan, R.M.,

Measures of Harm from Heavy Metal Pollution in Battery Technicians’ Workshop within Ilorin Metropolis, Kwara State, Nigeria

“…The metals distribution in the environment is governed by the properties of the metal and influences of environmental factors (Khlifi & Hamza-Chaffai, 2010;Morufu & Clinton, 2017;Olalekan et al, 2018;Raimi & Sabinus, 2017). Despite the 92 naturally occurring elements, about 30 metals and metalloids are potentially toxic to humans, Be, B, Li, Al, Ti, V, Cr, Mn, Co, Ni, Cu, As, Se, Sr, Mo, Pd, Ag, Cd, Sn, Sb, Fe, Cs, Ba, W, Pt, Au, Hg, Pb, and Bi.…”

“…Despite the subject importance, this paper therefore assesses the soils anthropogenic influences, which has become necessary due to increasing population pressure on soil characteristics. These anthropogenic influences, most often been researched upon in the context of industrial production, transportation, mining, mechanic workshop, construction and manufacturing have resulted in increased heavy metals notably Zinc, Iron, Lead, Cadmium, Chromium, Copper and Manganese in the soils surrounding these activities and ultimately to the biosphere which call for further assessment on soils effects (Johan, 2011;Morufu & Clinton, 2017;Raimi & Sabinus, 2017;Olalekan et al, 2018). Interestingly, biological effects of metal can be beneficial or harmful to humans and the ecosystem.…”

“…Though, majority of metals (e.g., cadmium, mercury, and lead) in the ecosystem are non-essential and of no importance to biological systems, although some metals (e.g., cobalt, copper, chromium, iron, zinc, and manganese) are essential and are known for important biological functions in humans (Caussy et al, 2003;Odipe et al, 2018). Metal introduction into the soils have been through various natural and anthropogenic sources (Ajmone-Marsan & Biasioli, 2010;Wong et al, 2006;Raimi & Sabinus, 2017;Morufu & Clinton, 2017;Olalekan et al, 2018). The disposal of major anthropogenic sources which include electrical and electronic equipment, paints, pesticides, incineration of domestic waste, atmospheric deposition from industrial processes, and power plants, as well as, traffic-related activities such as fossil fuel combustion, spills of motor oil, and wear and tear of brakes and tires (Ajmone-Marsan & Biasioli, 2010;Wong et al, 2006;Morufu & Clinton, 2017).…”

“…It is mainly because of the magical substance only that earth's temperature is maintained reasonably uniform at an average of 16 o C. Man needs about 150 to 300liters of water every day for domestic purposes such as drinking, cooking, washing utensils, bathing, flushing toilet, aircooling, gardening etc. [4][5][6][7] Water has a number of properties to life that are of critical importance to life and the environment. 7 Water is the only inorganic liquid that occurs naturally.…”
