Pollution of soil with lead (Pb) and cadmium (Cd) has been gaining researchers’ attention because of their adverse health effects on the safety of the food chain and environmental health. Hence, their immobilization in the soil is of great interest to environmental scientists globally. In this study, eggshell-biochar modified with nanoscale zerovalent iron/activated carbon (ESB-nZVI/AC) were synthesized via carbothermal reduction synthesis and compared their immobilization efficiency at...
Radiation exposures from mining and mineral processing industries can lead to high incidence of disease conditions like nausea, lung cancer, sterility, fatigue, and diarrhoea among mine workers. The concentration of primodial radionuclides (238U, 232Th and 40K) in some selected mining sites in Nasarawa State, Nigeria, was examined in this study. Soil and rock samples from eight different mining sites were collected and analyzed for radionuclides activity concentration by gamma ray...
