自1968年以来,我们在黑龙江省开展环境地质工作的结果,初步发现黑龙江省克山病区的地质环境,是一个还原性的,偏酸性的,吸附介质很发育的环境,微量元素钼在这种环境中的活动受到限制,因而在克山病区的主要粮食作物玉米中,钼的含量偏低。黑龙江省克山病的发病率与当地玉米中钼的含量成负相关。
Since 1968, as a result of environmental geology work in Heilongjiang Province, we have initially found that the geological environment of Keshan Ward in Heilongjiang Province is a reductive, acidic environment where the adsorption medium is very developed. The trace element molybdenum is here Because of the limited activities in the environment, the content of molybdenum in the Kibing Ward, the main food crop, is low. The incidence of Keshan disease in Heilongjiang Province is negatively correlated with the content of molybdenum in the local corn.
