摘要

研究了模拟降雨对受环境气态和颗粒空气氟化物影响的草地氟化物浓度的影响。水平几乎没有或没有下降，但在草地内有相当大的变化。在实验室种植的禾草上撒上人工冰晶石的进一步实验，几乎没有证据表明模拟降雨会降低氟化物水平。得出的结论是，草地内部的变化太大，无法显示在初始氟化物水平下的降雨以及所使用的降雨速率和持续时间的影响，如果有的话。

The effect of simulated rainfall on grass fluoride concentrations

The effect of simulated rainfall on the fluoride concentration of established pasture grass that had been subjected to ambient gaseous and particulate air fluorides was investigated. Little or no reduction in levels was exhibited, but there was considerable variation within the sward. Further experiments using laboratory-grown grass (Lolium perenne) dusted with artificial cryolite gave little real evidence of reductions in fluoride levels on subjection to simulated rainfall. It was concluded that the variation within the sward was too great to show the effect, if any, of rainfall at the initial fluoride levels, and rates and duration of rainfall used.
