“…Also, the findings shows that the concentration of manganese and magnesium in Wukari hand dug well water exceeds the set permissible limit of [12] and NSDWQ*MPL, which corroborate the findings of [1] [3] [13]- [15] that asserts that ground water in some selected Nigerian settlements shows some elevated levels of toxic metals. This they observe is a source of worry considering the fact that typical settlementin Nigeria is devoid of basic infrastructure that makes life worth living.…”

“…People with Wilson's disease should consult their personal doctor if the amount of copper in their water exceeds the action level. Also, long term exposure to water that contains copper can cause irritation of nose, mouth and eyes which can lead to headache, dizziness, vomiting and diarrhea among other health hazards [13].…”

“…The high concentration values of iron has the potential of staining laundry, metal pipes for reticulation and scaling in pipes. It can also result in gene mutation leading to haemochromatosis whose symptoms include fatigue, weight loss, joint pains and ultimate heart disease, liver problems and diabetes [13]. The iron concentration of the sample ranges between 0.00 -0.30, when compared to NSDWQ*MPL and [12] limit, it is within the permissible limit of 0.3 mg/l as shown in Table 2.…”

Hand dug well water remains the major source of domestic (drinking) water in the city of Wukari. This study was aimed at the assessment of heavy metal concentration in hand dug well water from four land uses of abattoir (A), waste dump site (B), residential (C) and commercial (D) in Wukari Town, Wukari, Taraba State. There are about 76 hand dug wells in the study area and for the purpose of this study. Yamane (1967) sample size technique was adopted. Based on this, 95% confidence level and an error limit of 5% were adopted. Thus, four (4) For now, it can be concluded that hand dug well water in Wukari Town is fit for domestic use, but that efforts should be made to reduce the magnesium and manganese concentration by having control on the anthropogenic factors that lead to such high concentration levels or else, soon this source of water may become unfit for domestic use. It was recommended that aggressive public awareness and enlightenment on possible impacts of hand dug well water pollution from human activities should be embarked upon by relevant agencies. K. T.

“…Chronic consumption of water with iron overload (above 0.3mg/l) results in gene mutation resulting in haemochromatosis with symptoms such as fatigue, weight loss, joint pains, liver and heart disease. Other health effects include severe allergic reactions such as rash, itching, streaks of blood in stools, vomiting and stomach pains [35]. Generally, agricultural drainage water from pesticides and fertilizers, industrial effluents and run-offs in addition to sewage are responsible for large amounts of inorganic anions and trace metals introduced into the marine environment.…”

Aims: This study aimed to determine levels of trace metals in Qua Iboe river estuary (QIRE), Ibeno and estimate human health risk associated with water from the river via ingestion and dermal exposure. Method: Trace metals in water from QIRE was measured using atomic absorption spectrophotometer and human health risk induced by the trace metals in dry and wet seasons was investigated using mathematical models recommended by United States Environmental Potential Agency (USEPA). Results: The range for the different metals investigated in dry season were as follows: Pb (0.147 to 0.19mg/l), Cd (0.02 to 0.31mg/l), V(0.04 to 0.11mg/l), Cr (0.09 to 0.18mg/l), Ni (0.28 to 0.61mg/l), Fe (8.78 to 13.97mg/l), Zn (0.13 to 0.56mg/l). The results for wet season were: Pb (0.07 to 0.19mg/l), Cd (0.05 to 0.31mg/l), V (0.01 to 0.03mg/l), Cr (0.02 to 0.15mg/l), Ni (0.03 to 2.33mg/l), Fe (0.02 to 4.92mg/l), Zn (0.11 to 0.43mg/l). Concentrations of metals were above USEPA limits except Zn. The target hazard quotient (THQ) and hazard index (HI) values via ingestion of water were greater than one while the THQ values via dermal contact were greater than one for Cd only. The combined target hazard index (HI*) from ingestion and dermal contact of water was greater than unity for Cd, Cr and Pb for wet and dry seasons. Conclusion: Findings in this study show that Pb, Cd and Cr may contribute to health risk from dermal and oral exposure to water from the QIRE systems. Constant monitoring and remediation processes of the QIRE are strongly recommended.

“…With serial dilution of the standard solutions into a series of seven 50 ml volumetric flasks, calibration curve was done for Ca, Cu, Mg, Cd, Pb, Cr and Zn. The determinations were carried out according to the standard methods for water quality (Kimete et al, 2010;Ekere et al, 2014) To ensure the removal of organic impurities from the samples and thus prevent interference in the analysis, the samples were digested with concentrated nitric acid. 10 ml concentrated HNO3 was added to 50 ml of water in a 250 ml conical flask.…”

Metal contamination in water is a major determinant of water quality. People who consume this water suffer from water borne diseases. There are various natural and anthropological activities at the sample collection site leading to increase in concentration of trace elements in drinking water. Activities like corrosion of metal coated pipes, herbicides, insecticides, ceramic wastes, taking gravel from near water source, etc. may lead to pollution of drinking water by heavy metals like chromium. The objective of this study was to detect metal concentration in spring and tap water from selected residential areas in the Gurage Zone. Tap water samples were collected from seven different locations during the rainy season. Samples were analyzed using atomic absorption spectrometry to determine the concentration of dissolved metal. Metal analysis was done to detect chromium, copper, zinc, lead, cadmium, magnesium and calcium. The results obtained were compared with guidelines for drinking water quality such as the World Health Organization (WHO) guidelines.
