Aerosols and their Effects

Aerosols, defined by dictionary.com, are substances packaged under pressure with a “gaseous propellant for release as a spray of fine particles.”  Aerosols in the ozone layer come from everyday products like hairspray, cans of paint, and other things like air conditioners.  Some aerosols are natural, like dust, sea salt, and volcanic ash.  Dust and sea salt are mainly the only two "natural" aerosols and they are the most abundant in the atmosphere, leaving man made aerosols with a smaller percentage in the atmosphere.  

Aerosols affect climate and weather because it helps with chemical changes in the atmosphere.  The particles mixed in with the ozone particles get hot from the sun and harmful rays, causing the aerosol particles to burn the ozone.  The burning of the ozone lead to a warmer climate because of allowing more UVB rays into the Earth’s atmosphere.  Basically, aerosols are a leading factor to the harm of humans.  Aerosols give the same effects to humans, because they are one of the leading causes for the depletion of the ozone.  The small difference is, every human and other living thing breathes in most of these aerosols.  Some, like man made chemicals, can cause great damage to one's health.
