The World Health Organization says diesel fumes cause lung cancer, according to The New York Times. The fuel's exhaust is considered to be more carcinogenic than secondhand cigarette smoke, said WHO, adding that it is a likely cause of bladder cancer. The American Cancer Society will probably reach the same conclusions soon, the New York Times reports. The ruling could have an impact on American workers heavily exposed to diesel exhaust, such as tollbooth attendants, the newspaper says. The study could also have an impact on the public's perception of diesel vehicles, which have grown more popular over the past decade. Diesel advocates note that the WHO study mainly focuses on older diesel technology and not vehicles that use low-sulfur or ultra-low-sulfur fuel, which is mandatory in the U.S.
