After Legal Fight, NCI Researchers Publish Study Linking Diesel Exhaust, Cancer

Posted by timothy on from the the-truth-will-out dept.

ananyo writes "A landmark study involving U.S. miners that links cancer rates to diesel fume exposure has been published after a seventeen-year legal battle with an industry group. A February 27 Slashdot story had reported that lawyers for the mining industry had sent threatening letters to scientific journals advising them against publishing the study. Initiated in 1998, after the first of many legal delays, the study analyzed exposures in detail for more than 12,000 workers while controlling for smoking and other risk factors. In the end, the scientists found that miners faced a threefold risk of lethal lung cancer, and underground workers who were heavily exposed to diesel fumes faced a fivefold risk. The two concluding papers from the study are available in full."

    I always wondered why many states require passenger cars to pass through strict emissions tests, however it is perfectly OK to have trains, dump trucks, buses, and large vehicles spew columns of dark black diesel exhaust into the sky....

    oh yeah...FIRST!

      As the short answer to that, well-maintained big diesel engines have a useful lifetime measured in millions of miles. Decades of use.

      Believe it or not, (most) emissions rules do apply to those vile soot-belchers (at least, the non-road ones); It will just take literally 50 years to cycle through the worst-of-the-worst currently in service.

      Yes, and the standards are getting more stringent. I think the most strict rules go into effect in 2015, and at that point the railroad engines will require DEF to meet the emissions standards, unless someone comes up with something amazing between now and then.

      Your other point is right on target, too - old locomotives are often rebuilt and reused, which is probably better for the environment than building a new one would be, even if the new one is more fuel efficient or runs cleaner. There are locomotives in service from manufacturers that have been out of business for 40 years.

  3. "Heavily exposed" by Kupfernigk · · Score: 5, Informative
    In fact, most developed countries outside the US, and some states inside, have strict rules on Diesel exhausts. Possibly over-strict given the relative lack of control of gasoline emissions from hot gas-powered trucks.But these people were being heavily exposed. When I worked in Diesel R&D, the engine test cells were carefully extracted and exposure to exhaust was very restricted. And for years many heavy vehicle workshops have tubing to remove exhaust fumes safely. The engine room ventilation systems on motor ships ensure that not only exhaust, but also under-piston and oil fumes, never go near engineering staff.

    You could say that perhaps the industries with perhaps the greatest in-depth knowledge of these engines have taken the greatest precautions against long term exposure of staff.

      Or you could also say that well trained and educated people are valuable employees and are well protected, while miners are to this day still treated as disposable. Maybe I'm more bitter than you, but I think we're both right.

    And the best rationalization of all: "if I don't do it, the next guy will, anyways. So the outcome will be the same, except I'll be the loser." And it's often true. It's the main reason why the world really does need ugly things like regulations.
