Grass can absorb and retain gaseous fluoride from ambient air. This fluoride then is absorbed by cattle eating the grass. The accumulation of this fluoride in their teeth and bones can damage their health and productivity. Critical concentrations of fluoride in grass have been defined. New data describing the relationship between amount of fluoride in air and fluoride in leaves of grass have been assembled and expressed by a regression equation. This equation can be used to predict fluoride accumulation in grass near a planned industrial project, and the likelihood of effect or damage in grazing cattle can be judged.
草可以吸收并留存周围空气中的气态氟化物。然后，食用这种草的牛会吸收这种氟化物。这种氟化物在牛的牙齿和骨骼中的积累会损害它们的健康和生产能力。已经确定了草中氟化物的临界浓度。描述空气中氟化物含量与草叶中氟化物之间关系的新数据已被汇总，并通过回归方程表示。该方程可用于预测规划中的工业项目附近草中氟化物的积累情况，并判断对放牧牛产生影响或损害的可能性。
