What are the harmful effects of CFC?
Why are CFCs and HFCs bad for the environment?
- increased incidence of skin cancer and cataracts.
- immune system system damage.
- damage to terrestrial and aquatic plant life.
- increased formation of ground-level ozone (smog)
Which disease is caused by CFC?
Cardiofaciocutaneous (CFC) syndrome is one of the RASopathies and is a rare genetic disorder is typically characterized by unusually sparse, brittle, curly hair; relatively large head (relative macrocephaly); a prominent forehead and abnormal narrowing of the sides of the forehead (bi-temporal narrowing); intellectual …
Why we should not use CFCs?
Health Issues: CFCs and HCFCs are lighter than air, so they rise into the stratosphere, where ultraviolet light frees the chlorine. A single chlorine atom can destroy thousands of ozone molecules, thinning the Earth’s protective ozone layer.
Are CFCs still used in India?
Under the Montreal Protocol, to which India became a signatory in 1992, CFCs have to phased out in India and the developing world by 2010 and there are indications this deadline will be advanced by 4 years. Of all the substances banned by the Montreal Protocol, India currently produces and uses only seven.
Is CFC banned in India?
How are CFCs harmful to the environment and human beings?
When UV rays strike CFC molecules in the upper atmosphere, a carbon-chlorine bond breaks, producing a separate chlorine (Cl) atom. It’s the chlorine atom then reacts and destroys an ozone molecule (O3). The CFC molecules can last a long time in the upper atmosphere, so even a few molecules can destroy a lot of ozone.
Why are chlorofluorocarbons harmful to the environment?
By Tommy Doc. Chlorofluorocarbons, also known as CFCs, consist of chemical compounds made up of chlorine, fluorine and carbon. CFCs are particularly harmful when released into the atmosphere because of their destructive reaction with O-zone particles, which provide the Earth with a protective layer against UV radiation.
When did CFC become a major environmental problem?
“When we realized there was a very effective chain reaction, that changed the CFC investigation from an interesting scientific problem to one that had major environmental consequences,” Rowland told Chemical & Engineering News in an extensive interview in 2007.
How is refrigerated food bad for your health?
If food is stored in the right way, it is not harmful for your health. During the process of refrigeration and storage there is a loss of essential nutrients. Whenever you buy uncooked food like raw vegetables and fruits or chicken and meat or even cottage cheese make sure that you wash the food properly.
