![]() ![]() Work place assessment and interviews were conducted. A structured questionnaire was used to collect socio-demographic information from the participants. To access the effect of mercury exposure on the renal function and level of personal protective equipment (PPE) compliance among small-scale gold miners in Bibiani District of the Western Region of Ghana METHOD: 110 consenting male gold miners were purposively recruited for this study. Artisanal and small-scale gold mining (ASGM) is the main source of direct human exposure to mercury. Mercury is a toxic metal with its effects on human health ranging from acute to chronic in a very short time of exposure. Reduced egfr, elevated urine protein and low level of personal protective equipment compliance among artisanal small scale gold miners at Bibiani-Ghana: a cross-sectional study.Īfrifa, Justice Essien-Baidoo, Samuel Ephraim, Richard K D Nkrumah, Daniel Dankyira, Daniel Osei In most of the water samples the concentrations of the toxic elements As, Cd and Hg were above Chromium was 19 - 87 mg/kg in the tailings. Mercury was in the ranges, 0.34 - 4.93 mg/L in the water, 0.01 - 0.06 mg/kg in the soil and tailings and 0.01 - 0.59 mg/kg in the plantain and cassava. The concentrations of cadmium were in the ranges, 0.35 - 2.80 mg/L in water, 0.69 - 4.15 mg/kg in the soil and tailings and 0.04 - 0.21mg/kg in the plantain and cassava. The concentrations of As measured were in the ranges, 0.04 - 6.08 mg/L in the water samples, 4.6 xl 0-5 - 0.35 % in the soil and tailings and 0.17 - 0.39 mg/kg in the plantain and cassava. Varying concentrations of the elements AI, As, Br, Ca, Cd, CI, Cr, Cu, Hg, K, La, Mg, Mn, Na, Sb, Ti, V and Zn were measured in the various samples. All these values were below the lower limit of the range 6.5 - 8.5, the WHO pH range for good quality drinking water, indicating pollution. The pH values of the water samples were in the range 3.9 - 5.93. ![]() The pH and Eh of the water, soil and tailings were also measured as well as the moisture content of the soil, tailings, plantain and the cassava samples. All samples were irradiated with thermal neutrons using the Ghana Research Reactor - 1 (GHARR-l) facility. ![]() INAA could not conveniently measure the concentrations of Cd and Hg in the above samples. The PNAA method developed involving the use of dithizone as a chelating agent was able to conveniently and efficiently measure concentrations as low as 0.004 mg/kg of Cd in the plantain sample coded HP and 0.002 mg/kg of Hg in the cassava sample coded BSC. The concentrations of the toxic elements As, Cd, Cr and Hg and the potentially toxic and essential elements Al, Br, Ca, Cl, Cu, K, La, Mg, Mn, Na, Sb, Ti, V and Zn in water, soil, tailings, plantain and cassava samples collected from the Bibiani mining area have been measured using instrumental neutron activation analysis (INAA) and preconcentration neutron activation analysis (PNAA). International Nuclear Information System (INIS) Studies of toxic elements in Bibiani mining area using neutron activation analysis Mercury concentrations of non-filtered water was determined using the ICP-OES after reduction with stannous chloride (SnCl2. In the study, surfacewater and sediment samples were collected from seven streams that drain this mining community and analyzed for total mercury, organic mercury and elemental mercury. The project assessed the extent of mercury pollution of some rivers that drain the Bibiani-Anwiaso- Bekwai district which is a typical mining community in the south western part of Ghana.
