Strontium nitrate significantly better than using glycolic acid alone. As a divalent ion with an ionic radius similar to that of Ca (1.13 vs. 0.99 A, respectively), Sr ions resembles calcium's ability to traverse calcium-selective ion channels and trigger neurotransmitter release from nerve endings. It is thus used in electrophysiology experiments. In his short story "A Germ Destroyer", Rudyard Kipling refers to strontium nitrate as the main ingredient of the titular fumigant. Strontium nitrate Strontium nitrate is an inorganic compound made of the elements strontium and nitrogen with the formula Sr(NO). This colorless solid is used as a red colorant and oxidizer
Volatile organic compound air pollution can still be important for indoor air pollution. California's ARB uses the term "reactive organic gases" (ROG) to measure organic gases after public hearing in September 1995. The ARB revised the definition of "Volatile Organic Compounds" used in the consumer products regulations, based on their committee's findings. Health Canada classifies VOCs as organic compounds that have boiling points roughly in the range of . The emphasis is placed on commonly encountered VOCs that would have an effect on air quality. The European Union defines a VOC as "any organic compound having an initial boiling point less than or
