The signing of the Montreal Protocol in 1987 led to aerosol propellants changing from halocarbons to less damaging replacements; around 93% of current aerosol emissions by mass are volatile organic compounds (VOCs), with small contributions from compressed air (6.6%) and fluorocarbons (0.4%). The global ...
Today, there are thousands of products packaged in aerosol cans -- everything from hair spray to cooking oil to medicine. In this edition of HowStuffWorks, we'll examine the basic principle behind these devices as well as the major mechanical elements at work inside.
