地表微量元素含量对环境及农业的影响

本文利用1:20万区域化探资料,研究了微量元素在土壤和水系沉积物中的分布,明确了元素含量在水系沉积物中基本能反映土壤中元素含量的变化趋势。通过研究微最元素含量分布对人体健康及农作物的影响,确定了Γ、Cu、Sn、MgO、Be、Mn、Ni、Sr、Cd等元素过剩或缺乏与地方病的关系,明确了Zn、Cu、Mo、P、K₂O、Mn等元素对农作物产量的影响。对区内与地球化学环境直接有关的疾病进行了预测。

THE EFFECTS OF SURFACE MINOR ELEMENT CONTENTSON ENVIRONMENT AND AGRICULTURE

Using 1,200000 regional geochemical prospecting data, the authors have reached the conclusion that minor element contents of stream sediments can basically reflect the variation trend of element contents in soil. Based on a study of the effects of minor element distribution upon human health and crops, the paper had determined the relationship of the surplus or deficiency of such elements as F, Cu, Sn, MgO, Be, Mn, Ni, Sr and Cd to endemic diseases, and made clear the effects of elements like Zn, Cu, Mo, P, K₂O and Mn on crop output. A prognosis has been made concerning the diseases directly related to geochemical environment of this area.
