What is the target concentration for fluoride in the drinking water system?

• A. 0.5 mg/L
• B. 0.8 mg/L
• C. 1.2 mg/L
• D. 1.5 mg/L

Answer: (B)

The target concentration for fluoride in drinking water systems is designed to balance the benefit of dental health with the potential risks of excessive exposure. A concentration of 0.8 mg/L is recommended as it efficiently helps in the prevention of dental caries (tooth decay) while limiting the risks associated with higher fluoride levels, such as dental fluorosis and other health issues. This level is often supported by public health guidelines and has been established based on extensive research regarding fluoride’s efficacy in improving dental health when consumed regularly over time. The other concentrations listed, while they reflect different historical standards or guidelines, either do not align with the most current public health recommendations or can pose a greater risk of adverse effects associated with higher fluoride intake.
