chlorofluorocarbon

Chlorofluorocarbons are harmful to the ozone layer.

The use of chlorofluorocarbons in aerosol sprays has been banned.

Scientists have found a decrease in chlorofluorocarbon levels in the atmosphere.

Chlorofluorocarbons contribute to the greenhouse effect.

The production of chlorofluorocarbons has been regulated by international agreements.

Chlorofluorocarbons are commonly used as refrigerants in air conditioning systems.

The Montreal Protocol aims to phase out the use of chlorofluorocarbons.

Chlorofluorocarbons are persistent pollutants that can remain in the atmosphere for many years.

The illegal release of chlorofluorocarbons can lead to environmental damage.

Chlorofluorocarbons were once widely used in the production of foam insulation materials.

The 1987 Montreal Protocol phased out the use of chlorofluorocarbons, or CFCs, responsible.

The long lifetime of the chlorofluorocarbons is a big part of the problem.

NASA's James Webb Space Telescope, due to launch in 2018, should be powerful enough to detect chlorofluorocarbons, CFCs.

Chlorofluorocarbons were once widely used in many products.

It is the second most common kind of CFC, short for chlorofluorocarbon.

The two chemists discovered that chlorofluorocarbons, or CFCs, from air conditioners and canisters of hair spray could destroy the ozone layer.

It was easy to find substitutes for chlorofluorocarbons in spray cans that took, you know, less than a year to do.

To compound the problem, the liquids used for all this comfort — first chlorofluorocarbons and now hydrofluorocarbons — are super-strength greenhouse gases.

By the mid-1930s, most refrigerators and air conditioners used chlorofluorocarbons – sometimes known under the trademark Freon – which were non-flammable, and safer to use.

About 80% of the chlorine in the atmosphere is a legacy of chlorofluorocarbons, chemicals used in aerosol sprays and as refrigerants starting in the 1930s.
