Abstract: The fluoride content of banana leaves which came from four areas and the bananaleaves of different degrees of withering was determined.The result indicated that thefluoride content of the banana leaves that came from polluted areas was much morethan the content of those coming from clean areas.The fluoride content of the firstand the eighth leaves which came from clean areas was almost similar.Thefluoride content of the first leaf and the eighth leaf which came from polluted area wasvery different.The fluoride content at each spot on the normal leaf was almost identi-cal,whereas the fluoride content at each spot on the withered leaf was very different.The fluoride content showed incremental trend from the middle vein to the edge of aleaf.The fluoride content of the banana leaves of different degrees of withering wasmuch more than that of the normal leaf.Because of the accumulation of fluoride ina leaf,the baana leaf wilted.
