“…Metal concentrations in the surface water were lower than those measured in a tropical manmade lake Southwestern Nigeria [33]. Similarly, the metal concentrations were also lower than those measured in River Balogun which had metal concentrations higher than WHO standards [34].…”

This study evaluated physical and chemical properties and calculated the Water Quality Index of the Anya Ogologo River in Rivers State, Nigeria. Four stations along the river were identified for this study based on accessibility and activities taking place on the river bank. Water and sediment sample collection were conducted once a week every month spanning a period of four months (February-May). In-situ measurements of surface water were taken for the following parameters: pH, salinity, electric conductivity, total dissolved solids, dissolved oxygen and temperature. Surface water was collected from each station to the laboratory and analysed for phosphate, nitrate sulphate, biochemical oxygen demand, and metals (lead, cadmium, manganese and copper). The parameters studied showed variations across stations. Sediment samples indicated the presence of manganese and copper metals. The WQI values observed were as follows; station 1: 55.07%, station 2: 43.58%, station 3: 56.29% and station 4: 67.10%. This indicates that generally the river is unsuitable for drinking, swimming, irrigation particularly.

Constant drinking water monitoring schemes are necessary because hazardous substances tend to enter water bodies through geodetic and anthropogenic sources. The main goal of this study was to evaluate the human health risk assessment posed by high fluoride and iron concentration in tap water used for domestic activities and consumption. In this study, the concentration of fluoride in tap water varied at different locations, ranging from 0.48 mg/L to 1.84 mg/L with an average value of 1.23 mg/L while that of iron ranged from 0.02 to 2.96 mg/L. The cluster analysis displayed three popular groups in which the samples can be classified. The non-carcinogenic risk was determined with defined methods outlined by US EPA considering dermal and ingestion pathways. Total Hazard Index greater than 0.8 for fluoride consumption in the analyzed locations was obtained from location R16, R17, R15, R4, and R6.

“…Another parameter that varied as explained were the body weight of the different categories. The body weight (kg) varied at 9.1, 29.3, 54.2, 67.6, 67.6, 78.8 and 80 [6] and finally, average time (ATr) in Days was constant at 2190 for the first four age groups and also constant at 7300 for the last three age groups as well [6] .The values presented in Table 2 are in accordance with laid down models or equations approved by United States Environmental Protection Agency (USEPA) and have been used in several studies in the literature [6] , [8] , [9] , [10] , [11] for estimating the chronic daily dose (CDD) or average daily dose (ADD) of heavy metals measured in mg/kg/day. The values obtained through laboratory analysis (see Table 1 ) are inputted into Eqs.…”

“…In addition, the

measured in mg/kg/day stands for a maximum acceptable oral reference dose for a typical heavy metal varies for different metals. Table 2 presents the values of

for different metals obtained in this study [9] , [10] , [15] . Several literatures have established that a risk is very likely when the

is equal or greater than unity while the probability of a risk not occurring is postulated when

is less than unity [16] , [17] , [18] , [19] .…”

Heavy metals find their way into surface and groundwater due to degrading environmental conditions, and as such consistent monitoring to avoid the adverse health implications associated with the consumption of polluted water is required. This study examined the concentrations for Lead (Pb), Nickel (Ni), Zinc (Zn), Chromium (Cr), Cadmium (Cd), Copper (Cu) and Arsenic (As) in the Surface water of River Balogun in Ota, Ogun State, Nigeria during the wet season and estimated the human health risk resulting from prolonged consumption by children and adult of dissimilar age groups without treatment. Although there were persistent occurrence of Nickel (Ni), Copper (Cu), Zinc (Zn) and Arsenic (As) in all stations sampled, the health risk assessment conducted revealed that both population groups are more likely to be affected by high concentration levels of Arsenic than any other Heavy metal present.
