Aerosols effect on the environment

This articles discuss about aerosol. The aerosol spray cans today, while much smaller and more refined, are direct descendents of those original military grade clunkers. Use of the cans for consumer applications took off during the ensuing decades, until the mid-1970s when ozone depletion first came to the public’s attention.
As a result, consumer aerosol products made in the U.S. have not contained ozone-depleting chemicals-also known as chlorofluorocarbons (CFCs)-since the late 1970s, first because companies voluntary eliminated them, and later because of federal regulations. Clean Air Act and U.S. Environmental Protection Agency (EPA) regulations further restricted the use of CFCs for non-consumer products. All consumer and most other aerosol products made or sold in the U.S. now use propellants-such as hydrocarbons and compressed gases like nitrous oxide-that do not deplete the ozone layer. Aerosol spray cans produced in some other countries might still utilize CFCs, but they cannot legally be sold in the U.S.
