Middle East Conflict Causes Fluoride Shortage in U.S. Drinking Water, Affecting Public Health Measures
The ongoing conflict in the Middle East has led to a significant shortage of hydrofluorosilicic acid, a chemical used to fluoridate drinking water in the U.S. This shortage has forced water systems, including Baltimore's, to reduce fluoride levels from 0.7 mg/L to 0.4 mg/L. The chemical is primarily sourced from international producers, and disruptions in the supply chain have been exacerbated by the conflict, particularly affecting production in Israel. Approximately 60% of the U.S. population relies on fluoridated water to prevent cavities, a public health measure that reduces cavities by about 25%. The shortage is unprecedented, and while the water remains safe, the reduction in fluoride could impact dental health if the situation persists.
