Risk and Toxicity Assessments of Heavy Metals in Tympanotonus fuscatus and Sediments from Iko River, Akwa Ibom State, Nigeria

Abstract: This study evaluates the physico-chemical parameters and heavy metals in water, sediments and Tympanotonus fuscatus obtained from three sample sites along Iko River in Eastern Obolo LGA, AkwaIbom State. The heavy metal analysis results on Pb, Cd and Ni in sediments and Tympanotonus fuscatus were used to estimate the human health and ecological risk assessment of the study area. The human health risk assessment tools utilized in this study were estimated dietary intake (EDI), total hazard quotient (THQ) and haz… Show more

“…Higher Ni concentration in plants was recorded by Bal et al, [16]. According to Ubong et al, [24], Ni in Tympanotonus fuscatus and sediments of Iko River ranged from 0.77±0.3 -83.6±0.2 mg/kg and 2.42±0.3 -91.6±0.2 mg/kg, respectively, which is largely higher than the amounts recorded in this study.…”

“…The increased use of metal-based fertilizer in agricultural revolution of government could result in continued rise in concentration of metal pollution in fresh water reservoir due to water run-off" [2]. "As human population increases, the intensity of anthropogenic threat exerted on the environment increases as a result of industrialization and agricultural activities [3]. Apart from soil environment and aquatic ecosystem, atmospheric inorganic contaminants of natural origin or anthropogenic sources that contained heavy metals and/or trace elements such as Cadmium (Cd), Chromium (Cr), Cobalt (Co), Copper (Cu), Nickel (Ni), Lead (Pb) and Zinc (Zn) at high concentrations could led to serious ecological consequences and pose human health risks" [4].…”

“…Short term overexposure is not known to cause any health problem but long-term exposure can decrease body weight, liver damage and skin irritation. In another study conducted by [6], Nickel occur in the environment at very low levels but it can be dangerous when the maximum tolerable amounts are exceeded. Although it is not normally added to chicken diets, but nickel has been detected in liver, kidney and muscle of broilers [2].…”

“…"The presence of heavy metals in an environment alters the structure and functions of the ecosystem due to the fact that their presence has effect on the nature of the physical and chemical properties of the soil. As human population increases, the intensity of anthropogenic threat exerted on the environment increases as a result of industrialization and agricultural activities" [4]. "Apart from soil environment and aquatic ecosystem, atmospheric inorganic contaminants of natural origin or anthropogenic sources of heavy metals could led to serious ecological consequences and pose human health risks" [5].…”
