We should also remember that freon leak is also dangerous, that's why it is advised that we must have our cars checked regularly. In my end, I go to my car shop weekly, you can visit them http://www.smartautomotive.com.au/ This is common here in NT, Australia, during summer it gets so hot and the humidity is really high, so car owners fight the heat with car air-con.

It also misinforms on what is an "acceptable" level of benzene exposure. I checked it on <a href="http://www.snopes.com/medical/toxins/benzene.asp" rel="nofollow">snopes.com</a>. As the Mythbusters would say, "busted". Although benzene is a carcinogen and a constituent in both plastics and fuel, auto components don't off-gas to that extreme. In fact, a Korean study found exposures higher during winter months. OSHA's <a href="http://www.sciencelab.com/xMSDS-Benzene-9927339" rel="nofollow">permissable exposure limit (PEL) for benzene</a> is 1 part per million (PPM) over an 8-hour time-weighted average (TWA) or 5 PPM in 15 minutes. There is no authoritive basis for the claim 50 mg per sq ft is acceptable. In fact, <a href="http://www.osha.gov" rel="nofollow">OSHA</a>'s TWA converts to 16 mg/cubic meter which equals 4.8 mg/sq ft. Thus 50 mg/sq ft is excessive and is even double OSHA's short term exposure limit of 24.38 mg/sq ft. This has no basis in fact.
