3 animals per group exposed to non-radiolabelled sulfuryl fluoride were sacrificed after 2 and 4 hours of exposure and 2 4 8 and 20 hours post exposure to measure fluoride ion content.

Fluoride environment pollution. Arsenic and fluoride have been recognized by the World Health Organization WHO as the most serious inorganic contaminants in drinking-water on a worldwide basis. Inorganic arsenic is the most common type of arsenic in soil and water. The metalloid arsenic can occur naturally in groundwater as seen most frequently in Asia including in China India and Bangladesh.

Fluoride ˈ f l ʊər aɪ d ˈ f l. With its concentration increasing significantly upon exposure to volcanic activity or atmospheric pollution derived from burning fossil fuels or other sorts of industry particularly aluminium smelters.

Fluoride is a neurotoxin which in high doses can be harmful. Excessive exposure can lead to tooth discoloration and bone problems. There is enough fluoride in the.

Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on. Hydrogen fluorideHF hydrogen chlorideHCl and bromide oxideBrO are three other volcanic aerosols which also contribute to international pollution.

Hydrogen fluoride and hydrogen chloride are both compounds outgassed into the atmosphere where they are then dissolve in water droplets. Once these two compounds are introduced to water vapor they become hydrofluoric and hydrochloric acids. Plastic pollution is one of the biggest problems humans need to overcome in the coming years.
