英文摘要About 160 samples of coal, corn, capsicum and drinking water were collected from endemic fluorosis area of Zhenxiong and Weixin County, Zhaotong City of Yunnan Province, to determine the arsenic (As), selenium (Se), and mercury (Hg) content by AAF-800. The study found that the As content in the main coal seam from the Late Permian coal mines in Zhaotong City is 8.84 mg/kg, and some civil coal can reach 89.09 mg/kg. The Se and Hg in the coal samples of Late Permian is lower, but Se and Hg are more concentrated in the pyritic coal balls and the pyritic gangue of the coal seam. The As content in coal-burning dried corn and capsicum contain more than 0.7 mg/kg the natural standard amount of arsenic content allowed in food by China. The Se and Hg content in the coal-burning dried corn is lower than the natural standard of Se and Hg content in the food of China, but Se and Hg content of coal-burning dried capsicum is exceed the amount allowed by the natural standard in food of China. Clay was used as an additive for the coal-burning process and as a binder in making briquettes, contain a high content of As, generally more than 16 mg/kg. However, the Se and Hg content of clay itself are low. The As, Se and Hg content of drinking water are lower than the natural standard of As, Se and Hg content in the drinking water. So, there are high-As content coal and high-As content coal-burning dried corn and capsicum in the endemic fluorosis area of Zhaotong City of Yunnan Province. The high As content of the dried corn and capsicum might have originated from the high arsenic content of burnt coal and clay.
