Mobilisation And Attenuation Of Arsenic Around Gold

This study assessed the concentrations of arsenic and iron in paddy soil and rice grain samples collected from the Nobewam and Odumase paddy field sites in the Anum Valley of Ghana as a means of determining the impacts of gold mining activities in the area on rice production The arsenic content of rice grains from the Anum Valley paddy fields was compared to that in rice grains of the same.The most notable is the 237 000 tonnes of arsenic trioxide stored in underground chambers There are five stopes and 11 chambers at Giant Mine that contain arsenic trioxide dust Between 2001 2003 extensive scientific and technical research and community consultation took place to determine the safest way to manage arsenic trioxide underground.
