Abstract: Fluorine is a very reactive element that does not occur naturally in its state. It is present as fluoride (F) and corresponds to about 0.3 g kg-1 of Earth's crust. Generally, it is found in the form of a number of minerals like fluorspar, Cryolite and Fluor-apatite and it is also discharged into the atmosphere through brick production plants, production of phosphate fertilizers (with an average of 3.8%), cement and other industrial processes. Fluoride has both positive and negative effects on plant health. Hydrogen fluorides (HF) in gaseous form accumulated in the leaves of sensitive plants against a concentration gradient and therefore, considered as a most phytotoxic air pollutant, which affects plants at extremely low concentration. HF mainly damages the plant by entering into its body in the form of gas and affects a variety of plant physiological processes. As HF accumulated in the leaves of plants which could endanger the health of humans and animals through the food chain.
