Worth thinking about? Not hardly.
Let me guess-you got that in an email (probably a chain email), correct?
For the most part it's a lot of nonsense. Let's cut it apart and look at the claims vs. reality.
"No wonder more folks are dying from cancer than ever before."
Nope. The age-adjusted cancer death rates in the United States have been decreasing for the past 2 decades
"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."
Nope. The closest you get is a 2007 German study on “Toxicity of Parked Motor Vehicle Indoor Air” which specifically tested the health effects of emissions from one new and one three-year-old vehicle exposed to “parked in sunshine” conditions found “no apparent health hazard of parked motor vehicle indoor air.”
"My car’s manual says to roll down the windows to let out all the hot air before turning on the A/C. WHY?"
Simple. On a sunny day, the fastest way to cool down a hot car interior is to open the windows. That's the biggest temperature gradient, and the hot air from the car rises and is expelled out the windows. It has nothing to do with any sort of gas build-up.
"Acceptable Benzene level indoors is: 50mg per sq.ft."
Nope. That right there tells you whoever authored the chain email is an idiot. The standard way to report levels of chemicals in air is mass per volume (for example, mg per cubic meter or cubic foot), not mass per area (mg per square foot).
I would highly suggest that when you receive a chain email, you simply press the delete button. Very, very few chain emails are factually correct, and passing on the ones that aren't just make you look foolish.
