【Abstract】 Thallium concentrations of the pyrite containing thallium and some kinds of products in the sulphuric acid factories have been determined. Thallium concentrations ranged from 10.0×10 -6 to 56.4×10 -6 in various kinds of pyrite, about 50×10 -6 in the pyrite tailings, from 21.7×10 -6 to 45.4×10 -6 in the sulphuric acid residues, from 30.2×10 -6 to 68.1×10 -6 in the furnace dusts, from 0.35×10 -9 to 7.86×10 -9 in the mine spring waters, 4.82×10 -9 in the mineral_dressing water, from 10×10 -12 to 30×10 -12 in the main_waters at the mine, from 55.2×10 -9 to 450×10 -9 in the stripping waters in the sulphuric acid factories, from 17.1×10 -9 to 37.9×10 -9 in the furnace dust waters, 4.22×10 -9 in the slag water and ranged from 9.30×10 -9 to 21.6×10 -9 in the discharge waters. Based on these data, thallium migration, transformation, diffusion processes and ecological pollution in the environment were discussed. It is suggested that the government should pay great attention to environmental thallium pollution and its consequence, take preventive measures and make actively harnessing technique research.更多还原
