Dear All,
Please read it carefully.

Car A/C (Air Conditioning) MUST READ!!!
Please do NOT turn on A/C as soon as you enter the car.
Open the windows after you enter your car, and then turn ON the AC
after a couple of minutes.
Here's why: According to research, the car's dashboard, seats, a/c ducts in fact ALL of the plastic objects in your vehicle, emit Benzene, a Cancer causing toxin. A BIG CARCINOGEN. Take the time to observe the smell of heated plastic in your car, when you open it, and BEFORE you start it up.
In addition to causing cancer, Benzene poisons your bones, causes
anemia and reduces white blood cells. Prolonged exposure will cause
Leukemia and increases the risk of some cancers. It can also cause miscarriages in pregnant females.
Acceptable Benzene level indoors is: 50mg per sq.ft.
A car parked indoors, with windows closed, will contain 400-800 mg of Benzene.
If parked outdoors, under the sun, at a temperature above 60 degrees F, the Benzene level goes up to 2000-4000 mg, 40 times the acceptable level.
People who get into the car, keeping the windows closed, will inevitably inhale, in quick succession, excessive amounts of the BENZENE toxin.
Benzene is a toxin that affects your kidneys and liver. What's worse, it is extremely difficult for your body to expel this toxic stuff from your body"

Most of the published studies wherein benzene levels were measured inside passenger vehicles have been done under driving conditions, in traffic. So, while such studies have indeed found that in-vehicle benzene levels can significantly exceed those outside the vehicle, and could pose a human health hazard, this is mainly attributed to the presence of exhaust fumes.

Also, the amounts of benzene actually detected by researchers, albeit significant, were much, much smaller than the amounts stated in the email. A 2006 study summarizing all the data collected to date reported in-vehicle benzene levels from exhaust fumes ranging from .013 mg to .56 mg per cubic meter — a far cry from the 400 mg to 4,000 mg per square foot (do they mean cubic foot?) reported above.

Benzene levels in parked cars

In the one study I was able to find that measured benzene levels inside parked cars with their engines turned off, the results were more benign. Toxicologists took samples of the air inside both a new and a used vehicle under simulated hot-sunlight conditions, measuring the levels of volatile organic compounds (VOCs) including C3- and C4-alkylbenzenes, and exposing human and animal cells to the samples to determine their toxicity. Despite the detectable presence of VOCs (a total of 10.9 mg per cubic meter in the new car and 1.2 mg per cubic meter in the old car), no toxic effects were observed. Apart from noting the slight possibility that allergy-prone individuals might find their condition exacerbated by exposure to such compounds, the study concluded there is "no apparent health hazard of parked motor vehicle indoor air."

When in doubt, ventilate

Despite this finding, some drivers may still be concerned about the presence of any benzene vapors inside their car, especially given the World Health Organization's stated position that there is "no safe level of exposure" to the carcinogen. They may also worry, per the email warning above, that turning on the vehicle's air conditioner might exacerbate their exposure to trapped toxins by recirculating contaminated air. If that's the case, there's no harm done — and much peace of mind to be gained — by simply opening the windows and ventilating the car before turning it on.
