They are emitted through a complex interaction of sunlight, unstable organic compounds from plants like trees, cars or industrial discharges, and other airborne chemicals. Secondary organic aerosols are a key component of fine particle pollution, which has been found to lead to lung cancer and heart issues and other health implications. Man-made and natural aerosols reaching the air are never a good thing for the macroclimate and microclimate. Created in many ways including everything from volcano explosions to desert winds, aerosol atoms reach the air and can play havoc with the temperature and weather patterns of neighboring areas.

Owing to the massive d eserts of Asia, strong wind carry silt as well as other particles into the air, and the elements collect over the Pacific Ocean.
