I-ejenti yokususa i-fluorine yi-agent ebalulekileyo yeekhemikhali esetyenziswa ngokubanzi ukunyanga amanzi amdaka ane-fluoride. Inciphisa ukuxinana kwee-ion ze-fluoride kwaye inokukhusela impilo yabantu kunye nempilo ye-ecosystems yasemanzini. Njenge-agent yekhemikhali yokunyanga amanzi amdaka e-fluoride, i-ejenti yokususa i-fluorine isetyenziswa ikakhulu ukususa ii-ion ze-fluoride emanzini.
