destruction of the ozone layer
Concurrent with the concern over ozone depletion is concern over global warming, which has generally been attributed to carbon dioxide emissions but also to emissions of certain refrigerants and methane.
Chlorofluorocarbon (CFC) is an organic compound that contains carbon, chlorine, and fluorine, produced as a volatile derivative of methane and ethane. They were commonly used as refrigerants, and for propellants for aerosol sprays, though they have been mostly phased out due to the fact that they cause ozone depletion.
Carbon dioxide and methane are naturally occurring greenhouse gases, but are also man made. CFCs previously used as propellants for aerosol and as refrigerants were really damaging greenhouse gases. These have since been replaced.

Althou I have never owned one my air conditioners have always been wall or window mounts. I have had experiences with portable ones, and they never leaked unless the plug in the back isn't working correctly

Any vehicle or other applicance that requires that fossil (or other hydrogen-containing) fuel be combusted, sending high temperature water vapor into the atmosphere. Note that much electricity is produced by combusting such fuels. Refrigerators, home / office cooling units that use CFC refrigerants will harm the ozone layer as they slowly bleed their charge to the environment. Spray cans for pharmaceuticals, cosmetics that still use CFCs as propellants will harm the ozone layer as they are directly vented to the environment.
Some costs that have been associated with this decision are that people have had to be evacuated from their homes and relocated, entire towns have had to be flooded, and many temples and places that indicate cultural history have been destroyed.

what are foods sources associated with it and possible contaminants
the amount of ozone in the atmosphere began to drop sharply in the 1980s . this decrease has been linked to synthetic chemicals like chlorofluorocarbons which are used in refrigerants and in fire extinguisher's .
Some of the problems with the 2010 bmw series 3 are engine knocks, exhaust system, steering noises, and transmission leaks. Most of the problems associated with this model have been fixed through a series of recalls.
