Dust, Dirt, and Death

Steve Milloy publishes JunkScience.com and is the author of Green Hell: How Environmentalists Plan to Control Your Life and What You Can Do to Stop Them. Milloy has a column in the Washington Times which casts doubt on the credibility of the Environmental Protection Agency (EPA). The EPA, according to Milloy, claims that the air quality of American cities is responsible for the deaths of tens, maybe even hundreds, of thousands of people per year. They claim to know this because they've calculated that every 10 microgram-per-cubic meter of pollutants results in a 1% rise in deaths. But this calculation is suspect.

The Chinese city of Xi’an is among the worst cities in the world in terms of air quality. Yet using the same sort of data and statistical analysis employed by EPA-funded air quality researchers, the Chinese researchers reported having statistically correlated every 10 microgram-per-cubic-meter’s worth of fine particulate matter in Xi’an’s air with a 0.2% increase in the city’s death rate. Despite being almost ten times more polluted than the air in American cities, Xi'an's air is apparently five times safer.

Obviously, something is wrong somewhere, and Milloy thinks the problem is with the EPA's numbers. This is not just an academic exercise since the EPA figures are used to regulate the emissions allowed by various industries.

We want clean air as much as the next person but we want our standards to be based on empirical fact not on suppositions based on an ideological bias against fossil fuels.
