作者采用NC(?)-22型光谱仪测定了重发病区21处河水中的微量元素。测定的结果:所有发病区河水样品中的锌、锶、锰含量很高;钙和铜含量低。其含钙量为12.3～35.2毫克/升;含锶量为0.09～0.25毫克/升,钙∶锶=125∶40,而苏联水的平均含量资料:钙为100毫克/升;锶为0.5毫克/升,钙∶锶=200。显然,发病区的人比非病区的人食入的钙少锶多。作者还发现水中含铅和钼量高的地方,大骨节病患者多,而水中含钙量高的地区却无发病的。动物实验证明,给动物饲喂含锶量高的食物,可
The authors used NC (?) - 22 spectrometer to determine trace elements in 21 rivers of recurrent disease area. Determination results: all the incidence of river water sample samples of zinc, strontium, manganese content is high; low calcium and copper content. The calcium content is 12.3-35.2 mg / l; the content of strontium is 0.09-0.25 mg / l; calcium: strontium = 125:40; while the average content of Soviet water is 100 mg / l for calcium and 0.5 mg for strontium / Liter, calcium: strontium = 200. Obviously, the incidence of people than non-ward into the human calcium less strontium. The authors also found that water contains high levels of lead and molybdenum, Kashin-Beck disease in many places, while the water is high in areas without the incidence of calcium. Animal experiments show that animals fed foods containing high amounts of strontium can be
