摘要
Abstract
By ICP-MS, this paper measured heavy metal Cd content in rice in the periphery of a uranium mining area and a contrast area, and focused on study of Cd content and its spatial distribution features, and concluded that: (1) 10.53% of rice in the uranium mining area has Cd content over national standard (GB2762-2005) and 89.47% not, while in the contract area, Cd content is far below the standard; (2) Cd content in rice in the uranium mining area is far more than that in contrast area, Cd content in rice in tailings accumulation zone, hydrometallurgical mill and lower reaches of mining area and the periphery is evidently higher than that in the upper reaches and distant areas; (3) waste water and residues from mining zone, waste liquid seepage from hydrometallurgical mill, tailings storage in the open air, and mineral falls from transport may be the major factor that leads Cd into rice field with surface runoff thus causing rice in the mining area to have higher content of Cd.关键词
