摘  要: Although previous studies have been reported between the Kashin-Beck Disease (KBD) epidemic and the hydrochemical characteristics of surface waters, the etiology of the disease remains unclear. In the present study, we comprehensively investigated the relationship between the KBD and the hydrochemical characteristics of surface waters in Longzi County. Results show that, the pH (mean = 7.27 +/- 0.30), total hardness (TH, mean = 57.08 +/- 45.74 mg L-1), total dissolved solids (TDS, mean = 67.56 +/- 44.00 mg L-1) and oxidation-reduction potential (ORP, mean = 84.11 +/- 23.55 mV) of surface waters in KBD endemic areas are lower than those in the non-KBD endemic areas (means of pH = 7.49 +/- 0.30; TH = 262.06 +/- 123.29 mg L-1; TDS = 253.25 +/- 100.39 mg L-1; ORP = 215.90 +/- 55.99 mV). These results suggest that long-term consumption of low TDS, essential trace elements (e.g., nickel, cobalt, iron, selenium, zinc, molybdenum, and iodine) deficient, and potential toxic elements (e.g., arsenic) enriched waters by humans likely causes the KBD. Environmental factors such as the geology and geomorphology may produce biogeochemical imbalance, geomorphic, vegetation types and local climatic conditions may have significant impact on food fungi toxin poisoning and water organic compound poisoning, and these also impact the KBD occurrence.
