هل تحتوي المياه المتدفقة على الفلورايد؟
Could you kindly elaborate on whether flowing water naturally contains fluoride? I'm particularly interested in understanding if fluoride is a common component in various sources of running water, and if so, what are the potential implications for human health? Also, I'm curious to know if there are any methods to remove fluoride from water, especially in areas where the fluoride content is unusually high. Thank you for your insights.
