In addition to causing cancer, it poisons your bones, causes anemia, and reduces white blood cells. Prolonged exposure will cause Leukemia, increasing the risk of cancer. May also cause miscarriage.
Acceptable Benezene level indoors is 50 mg per sq. ft. A car parked indoors with the windows closed will contain 400-800 mg of Benezene. If parked outdoors under the sun at a temperature above 60 degrees F, the Benezene level goes up to 2000-4000 mg, 40 times the acceptable level.
