| People come to realize the function of hot spring water, health care, promote the benefits of springs, while ignoring the irrational use of hot spring have great harm on the environment. Fluorine spring water is one of harmful to the environment. In order to investigate the impact of fluoride spring water on the environment, the subject study Hongge spring water, Panzhihua City, Sichuan Province, we have a comprehensive and systematic analysis of the hot spring water,the surrounding rivers, soil and plant content of fluorine, Summed up the migration and characteristics of fluorine.The following conclusions:1. Hongge spring water fluorine up to 18.67mg/L,this content far beyond the WHO 1mg/L,which is high fluorine sping.2. Wastewater pollution of the surrouning water, during the analisis, the fluoride along the flow direction gradually decreased.From the sping water at the mouth of 2500m,fluorine have down to 1mg/L,this shows,after dilution of the river,fluoride content was reduced normal.3. Wastewater pollution of the surrouning soil,filde around the hot spring water,by the impact of the high fluorine sping water and irrigation water,the soil have high fluorine.During deteminition,high fluorine content in soil up to 1275.27 mg/kg,far beyond country average fluorine content in soil.4. Wastewater pollution of the surrouning crops,high fluorine content in soil lead to high fluorine crops.During determinition,fluoride content of vegetabales up 22.55mg/kg,compared to GB 4809─84≤1.0mg/kg vegetables fluorine content have seriously overweight.5.Fluorine form distribution in the soil ,during determinition,water solutble fluoride content up to 201.17mg/kg, water soluble fluoride is main part in the soil.so high water soluble fluporine is the main point lead high fluoride crops,we have realied the spring water have high fluorine ,because the high fluorine water will have seriously hazards to human being.so combine the above conclusion,the subject developted some except fluoride measures. |
