Abstract

  Effluents due to local and unprotective mining activities can elevate concentration of primordial radionuclides and thus pose serious health threat to population of people living in the mining environment. The effect of the mining activities in the studied areas so far has been an environmental concern. Stream water, well-water and water sediments were collected around local mining area of Ijero-Ekiti, Ijero local government area in Ekiti State Nigeria. The activity concentration of the radionuclides were measured with gamma ray spectroscopy (GRS). The results of activity concentration of radionuclides obtained as mean activity concentration of plutonium ²⁴²Pu, uranium ²³⁸U and thorium ²³²Th in water sediments from dug wells are 1208.8 ± 216.6, 58.7 ± 6.7 and 117.1 ± 94.9 Bq l^-1 respectively which are significantly (P < 0.05) higher than that obtained from dug well-water (262.2 ± 18.7, 16.5 ± 1.0 and 17.2 ± 1.8 Bq l^-1) and earth surface stream water (226.3 ± 18.5, 14.5 ± 1.9 and 14.8 ± 1.5 Bq l^-1) respectively in same location. The results from this study suggest that effluents from local mining activities may have elevated the activity of primordial radionuclides in the study area and this potends high cancer and hypertension risk for the entire populace. However, antioxidant and anticlastogenic properties exhibited by Podophyllum peltatum plant in this study could possibly justify the plant as dietary supplement to salvage the health risks in local mining areas.
