Objective In order to evaluate the safety of drinking water defluorodation by activated magnesia (a new defluorination agent) sperm aberration test of 6 months via drinking water defluorinated in mice was carried out. Method 20 mice were random divided into 5 groups: 2 groups of drinking defluorodation water (Mg 360mg/L, 180mg/L), 2 groups of drinking high fluoride water (F 100mg/L, 50mg/L)and a control group drink ing microfluoride tap water (F 0. 50mg/L). The morphology of sperm were tested in thee after drinking defluoroda- tion water and the water of high fluoride. Result Compared with control group the sperm aberration rates were not founded significantly changes (P 0. 05) in groups of drinking defluorodated wate and significantly increase in mice of high fluoride groups(P 0. 01 ). Conclusion The sperm aberration rate of mice were significantly in- crease after drinking high fluoride water, but no adverse effects of defluorodated drinking water on sperm morpholo- gy were noticed.
