Fluoride in plant and vegetable samples has beendetermined using the ion selective electrode.The analysis was carried out after ashingthe samples onan open flame, adding perchloric acid and allowing the hydrogen fluoride to diffuse into a sodium hydroxide layer. The results obtained show that kale and pumpkins can accumulate more than ten times their normal values of fluoridewhile plants were found to accumulate upto 100 ug/g fluoride when exposed to high levels of fluoride in water or soil.
