Cfcs in a sentence

Chemicals in the atmosphere CFCs and related compounds in the atmosphere Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion.

Regulatory gap While the production and consumption of CFCs are regulated under the Montreal Protocol, emissions from existing banks of CFCs are not regulated under the agreement.

Similar to CFCs, SF 6 is also an inert gas and is not affected by oceanic chemical or biological activities. citation Thus, using CFCs in concert with SF 6 as a tracer resolves the water dating issues due to decreased CFC concentrations.

The European Community rejected proposals to ban CFCs in aerosol sprays, and in the U.S., CFCs continued to be used as refrigerants and for cleaning circuit boards.

First, chemicals such as CFCs exist only because of technology.

Leaded gasoline, which in the end did far more harm to human health than CFCs, was actually a more manageable and preventable class of threat.

Emissions standards and transitioning to electric are no different from regulating power plant emissions or banning leaded gas or asbestos or CFCs or mandating smog checks.

On an international scale, the world witnessed this with the Montreal Protocol, which banned a class of gases called CFCs and halted the deterioration of the ozone hole, driven in part by fear of cancer and other human health issues.

China violates 30 year old treaty banning CFCs.

Compounds such as chlorofluorocarbons (CFCs), Halon (a firefighting chemical) and methyl bromide all began to be phased out of everyday use at that time.

Later amendments to the Montreal Protocol completely phased out production of CFCs.

Although decreases in stratospheric ozone are well-tied to CFCs and to increases in surface UVB, there is no direct observational evidence linking ozone depletion to higher incidence of skin cancer and eye damage in human beings.

As a consequence, the major halocarbon-producing nations agreed to phase out production of CFCs, halons, and related compounds, a process that was completed in 1996.

Because of their polarity, the CFCs are useful solvents, and their boiling points make them suitable as refrigerants.

Because the fluorine and chlorine atoms differ greatly in size and effective charge from hydrogen and from each other, the methane-derived CFCs deviate from perfect tetrahedral symmetry.

Bromine atoms are even more efficient catalysts; hence brominated CFCs are also regulated.

CFCs and other contributory substances are referred to as ozone-depleting substances (ODS).

CFCs, in contrast, are insoluble and long-lived, allowing them to reach the stratosphere.

Environmental impacts As previously discussed, CFCs were phased out via the Montreal Protocol due to their part in ozone depletion.
