Outdoor air is like secondhand smoke?
People who have never smoked, but who live in areas with higher air pollution levels, are roughly 20 percent more likely to die from lung cancer than people who live with cleaner air, researchers conclude in a new study.
But the study is of exceedingly poor quality — the researchers only used air pollution data for the periods 1979-1983 and 1999-2000 in a study that covers the period 1982 to 2008 — and its results are weak associations that are statistically insignificant.
You will not get a hint of any of that from the Reuters report.
BTW, the reported association (a 20% increase in lung cancer) is about the same as the 19% increase in risk the EPA calculated in 1993 for secondhand smoke.
