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 colorant added to tint paint may contain between 5 and 20 grams of VOCs. A dark color, however, could require 5-15 ounces of colorant, adding up to 300 or more grams of VOCs per gallon of paint. The exhaled human breath contains a few thousand volatile organic compounds and is used in breath biopsy to serve as a VOC biomarker to test for diseases such as lung cancer.<ref name="doi: 10.1002/bmc.835"></ref> One study has shown that "volatile organic compounds ... are mainly blood borne and therefore enable monitoring of different processes in the body." And it appears that VOC compounds in
