The tea plant takes up F from the soil and accumulates it in its leaves where it becomes a major source of F. As seen in Table 3, F content in tea leaves showed an increasing tendency as its concentration in the nutrient solution increased with a very high positive correlation (r=0.9667, p<0.01). A substantial amount of F is released during tea infusion and nearly all (about 94.9%) of the released F is absorbed by consumers (27).
Since there is increasing evidence that F exposure may actua
