Why do aerosols damage the ozone layer?
In the 1970’s scientists discovered that CFC’s were accumulating in the environment, and depleting the earth’s ozone layer. Modern-day, CFC-free aerosol sprays also emit volatile organic compounds (VOCs) that contribute to ground-level ozone levels, a key component of asthma-inducing smog.
Why are chlorofluorocarbons harmful to the ozone layer?
Once in the atmosphere, CFCs drift slowly upward to the stratosphere, where they are broken up by ultraviolet radiation, releasing chlorine atoms, which are able to destroy ozone molecules. The seasons have an impact on the Antarctic ozone hole. When sunlight returns in the spring, the chlorine begins to destroy ozone.
Why aerosol is harmful to the environment?
VOCs, contained in traditional aerosol cans affect the environment by constantly contributing to the formation of ground-level ozone. Other than that, once the pressurized gas or liquid is depleted and the can is empty, the metallic steel remains a hazardous waste to the environment.
Is aerosol bad for the ozone?
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. They still contain hydrocarbons and/or compressed gases notorious for their contribution to global warming.
Why is the use of chlorofluorocarbons being discouraged explain?
The use of Chlorofluorocarbons (CFCs) being discouraged because CFCs molecules were not settle in atmosphere and uv rays break these molecules which cause ozone depletion.
What are the negative effects of aerosol?
Other aerosols, like ozone, have also increased—with dramatic health impacts around the world. Air pollution has been linked to increased risk of heart disease, stroke, lung disease, asthma, and more.
What is the aerosol effect?
Aerosols can influence the Earth’s climate in two ways. When the sky is clear (devoid of clouds), aerosols can reflect incoming sunlight back to outer space – the direct effect. This blocks part of the energy that would have reached the surface, thus having a cool effect on the climate.
