How Can The Effects Of CFCs Be Described? - Quora

The most abundant CFCs emitted into the troposphere are CFC 11 and CFC 12. "Because CFCs are so long-lived in the lower atmosphere, there is ample time and opportunity for them to Chlorine released from this breakdown of CFC-11 and other CFCs remains in the stratosphere for several...Larger image to save or printGases that trap heat in the atmosphere are called greenhouse gases. The GWP takes into account the fact that many gases are more effective at warming Earth than CO2, per unit mass. Each of these gases can remain in the atmosphere for different amounts of time...Your work environment can greatly influence how you feel about your job. Here are four reasons why a positive work atmosphere is important in the workforce Because your mood and attitude affect your team members, a positive working environment can be a good influence on those around you.Large amounts of CO2 are emitted into the atmosphere from factories and motor vehicles, thus causing climate change, and leading to various [...] significantly reduced carbon dioxide (CO 2) equivalent emissions released into the atmosphere, both directly, through the replacement of CFCs...This is how carbon emissions affect the environment and the world we're living in. Anytime that carbon dioxide is emitted into the atmosphere in large quantities — especially if it's The amount of carbon emissions trapped in our atmosphere causes global warming, which causes climate change...

Chlorofluorocarbons (CFCs). Unburned hydrocarbons. Lead and heavy metals. They emit harmful chemicals into the air and can also cause water pollution. Farmers also set the field Manufacturing industries release a large amount of carbon monoxide, hydrocarbons, organic compounds, and...Pollutants emitted into the atmosphere by human activity include On release into the air, CFCs rise to the stratosphere. Here they come in contact with other gases and damage the ozone layer. Vegetation, in some regions, emits environmentally significant amounts of Volatile organic...Effects On Humans. People experience a wide range of health effects from being exposed to air pollution. Carbon dioxide is emitted into the atmosphere by burning fossil fuels (coal, gasoline, and natural gas). Fluorinated gases are often used instead of gases such as chlorofluorocarbons (CFCs).Also some aerosols release CFCs into the atmosphere. Not all CFCs have the same staying power in the atmosphere. The duration of their existence is measured as a half-fife CFCs can remain in the atmosphere for up to 75 years. CFCs are no longer being emitted to the atmosphere and scientists...

Even short-haul flights produce huge amounts of CO2, figures show. There are 56 countries where the average person emits less carbon dioxide in a whole year - from Burundi in Africa to The figures are averages taking into account which aircraft models are typically used on flight routes, and the...Atmosphere pollution affects the Earth for the long-term. Pollution will last well beyond the humans alive on the planet today. Humans also affect the atmosphere locally through air pollution. Even though CFCs were banned in the U.S. in 1985, their molecules live a long time in the atmosphere.How might this affect people? 121 views.Atmospheric CO2 levels are rising by 15 gigatonnes per year. Humans are emitting 26 gigatonnes of CO2 into the atmosphere. In some cases human-caused change is direct and unambiguous. The harmful effect of the human release of CFCs on the ozone layer is well documented and not disputed.Increasing the amount of CO2 in the atmosphere reinforces this effect and is expected to result in "Power plants and factories emit 90% to 95% of the sulfur dioxide and 57% of the nitrogen oxides in CFCs are lowering the average concentration of ozone in the stratosphere. "Since 1978 the use of...

Ozone holes could begin to shrink in dimension.

Explanation:

The use of CFCs as of late is one of the anthropogenic reasons of ozone depletion. CFCs are present in Air conditioners, refrigerators and are very good coolants.

When CFCs are released into the atmosphere, they react spontaneously with ozone.

Ozone is made up of 3 oxygen atoms and it serves as a protective protecting for the very damaging ultraviolet rays from attaining the earth. Ozone cuts off those radiation and it reflects them again into space.

Chloroflurocarbons unlock Chlroine atoms after they get damaged down by way of ultraviolet rays. The Cl released produces a sequence of reactions in the presence of ozone.

Chlorine is very reactive because it is an halogen. It calls for just an electron to finish its octet.

Chlorine freely reacts with the ozone producing a vary of compounds. Most of the ozone becomes oxygen molecules.

This would expend the ozone greatly. The increasing use of CFCs leaves holes in the ozone layer. The holes allow for harmful UV rays to achieve the earth surface. This can result in quite a lot of hurt on human lives on the earth floor.

This is why CFCs aren't authorized in appliances again.
