摘要：The motivation for this research work was the unprecedented death of animals and the appearance of debilitating illnesses in the MararrabanBirnin Yauri community. These deaths and illnesses are suggested to be associated to artisans in the business of gold mining. The artisans use the communities’ sources of water in extracting their gold. In the extracting of gold, artisans use chemicals that pollute water bodies used by humans and animals. This work collected water samples from three out four affected Sites and two major community source of drinking water for analysis using Investigated neutron activation analysis method. The choice of this method is informed by the evidence that the method is multielemental, non-destructive and safe. Results indicated the presence of fifteen elements: seven are naturally occurring four are alien to the community suggesting they are imported contaminants by the miners. The elements include the following: Al, B, Ca, Ch, Cl, Fe, Hg, K, Mg, N, Na, S, Pb and Zn. Human made contaminants include NaCN and Hg with concentration of 160 ppm and 2.8 ppm respectively. These concentrations are way high above the World Health Organization tolerable limits.
