What should be the tolerable limit of fluoride ions in drinking water? What happens if it is higher than10 ppm?
Answers
Fluoride is an ionic compound obtained from fluorine, and it is normally found in numerous stones. Around 95 percent of the fluoride added to open water supplies is delivered from phosphorus rock. Fluoride is added to open water supplies at a normal grouping of around 1 section for each million (1 ppm) or 1 milligram for every liter, or marginally beneath.
Normally happening fluoride fixations in surface waters rely upon area, however, are commonly low and more often than not do not exceeds 0.3 ppm. When this level increases it causes fluorosis which influences the teeth and bones. Moderate sums lead to dental impacts; however long haul ingestion of substantial sums can prompt conceivably extreme skeletal issues.
Answer: Tolerable limit : 1ppm
Higher than 10ppm : harmful effects to bones and teeth
