“…This is the first step of the risk assessment process that was used to establish a link between the toxic chemicals identified and their health effects on residents in the study area [21]. In this study, Hg, Cd, and As, were identified as possible hazards in the community when they drink directly from the river without treatment.…”

The rational for the study was to assess the levels of endocrine disrupting trace metals in River Samre. The levels of Mercury ranged from 0.01 to 0.02 mg/l (mean of 0.006 mg/l), whiles cadmium levels ranged from 0.002 to 0.011 mg/l (mean of 0.01 mg/l). The high levels of Hg and Cd may have adverse effects on the endocrine system of inhabitants who drink directly from the river without treatment. High levels of mercury and cadmium might be caused by the activities of a Timber and Plywood Company located close to the river and the underlying bedrocks of the area exposed as a result of human activities such as farming. The concentration of lead was below detection limit (<0.005 mg/l) but that of Arsenic ranged from 0.001 to 0.007 mg/l (mean of 0.005). Health risk assessment conducted shows that the risk associated with exposure to these metals for now are low. Continuous water quality monitoring is recommended to help protect the resource and also to safeguard human health.

“…Pb is a general toxicant that accumulates in the skeleton as well. Infants, children up to six (6) years of age and pregnant women are most susceptible to its adverse effects (Obiri et al, 2010;Centeno et al, 2002;ATSDR, 2007).…”

“…Mining operations may affect drinking water, especially in the rural areas that are largely dependent on hand-dug wells, boreholes or surface water. Many researchers have indicated that the presence of heavy metals in surface and groundwater cause serious health problems (Obiri et al, 2010;Koger et al, 2005;Weiss, 2000;Porterfield, 2000;Myers and Davidson, 2000).…”

“…Hg is toxic to the central and peripheral nervous system. Health problems associated with Hg include personality changes, deafness, changes in vision, loss of muscle coordination or tremors, loss of sensation and memory Hg can be passed from pregnant mothers to unborn children and also to babies through breast feeding (Obiri et al, 2010; Agency for Toxic Substances and Disease Registry (ATSDR), 1999).…”

The study assessed non-cancer human health risk from exposure to mecury (Hg), cadmium (Cd), arsenic (As), copper (Cu), and lead (Pb) in surface and groundwater in Tinga, in the Bole-Bamboi District. A total of 42 water samples were collected for a period of six months. Mean concentration of Hg, Cd, and Pb were found to be (0.050 ± 0.04 mg/L), (0.031 ± 0.02 mg/L) and (0.07 ± 0.05 mg/L), respectively. These were all above the World Health Organization (WHO) recommended guideline values for drinking water. Non-cancer human health risk as a result of exposure to Hg and Cd through ingestion of borehole water was found to be high. Hazard quotients (HQ) as a result of exposure to mercury for adults and children ranged from 2.5 to 30 through central tendency exposure (CTE) and 4.6 to 60 through reasonable maximum exposure (RME). For Cd, CTE ranged from 0.96 to 2.7 and RME ranged from 1.8 to 5.4. The HQ for exposure to Hg and Cd through ingestion of ground water exceeded the acceptable United States Environmental Protection Agency (USEPA) value of 1.0. This implies that resident children and adults are likely to develop diseases (such as low intelligent quotient, tremor, kidney failure, increased hypertension and cardiovascular diseases) associated with long term exposure to Hg and Cd.
