From Forbes:

The debate over air pollution and, more specifically, the regulation of air pollution, raged on this week as the Environmental Protection Agency (EPA) watered down its cross-state pollution rule and House Republicans moved to delay new rules on toxic air pollution from cement plants, solid waste incinerators, and industrial boilers.  These latest debates come on the heels of President Obama’s move last monthto reneg on promises to tighten up smog standards, a decision that angered environmentalists and led to speculation that EPA Administrator Lisa Jackson might be ready to walk. In all cases, the argument against regulation goes something like this: The last thing a down economy needs is new regulation, and the EPA is overstepping its boundaries.

These arguments center largely around the idea that current air pollution regulation is good enough as-is, and that any further restrictions are aimed at tackling environmental issues and climate change, both typically seen as luxuries in a down economy. But research is continuing to pile up in support of the claim that not only are current air pollution regulations inadequate, but that air pollution is very much a public health issue.

When viewed through the public health lens, the economic arguments against regulation of air pollution begin to unravel, particularly in the face of rising healthcare costs. Consider, for example, a spate of new studies that have found a rather convincing correlation between the presence of small particulate matter (PM2.5, the ultrafine particles blown into the air by road traffic, coal-fired power plants, industrial manufacturing, and residential wood fuel combustion) and both obesity and diabetes.

Medical research has long supported the fact that exposure to ultrafine particulate matter increases the risk of various respiratory, cardiovascular, and pulmonary illnesses. Incidences of asthma, heart attacks, and chronic bronchitis are all higher in areas where the concentration of ultrafine particulate matter is higher. The correlation between particulate matter and these health issues is particularly pronounced in children, as well as low-income communities, which are often located closer to the sources of particulate matter (highways, factories, power plants) than their higher income neighbors.

Over the past decade, new studies have emerged that link air pollution to two of this country’s most pressing (and expensive) health epidemics: obesity and type II diabetes. Both are not only on the rise in terms of diagnoses, but also in terms of the costs associated with treatment. According to a January 2011 study by the Society of Actuaries, the current cost of the obesity epidemic in the United States is $270 billion a year.  The American Diabetes Association puts the current cost of dealing with diabetes (over 90 percent of U.S. diabetes cases are type II) at $174 billion. According to the Center for Disease Control, asthma is a leading cause of school absenteeism in the United States, and the cost of treating asthma in children 18 and under alone is $3.2 billion per year. Meanwhile, financial analysts estimate the cost of tightened air pollution regulations at $130 billion. Granted, these are not budget line items that are easily swapped in for each other, but a tie-in to obesity and diabetes may just make tackling air pollution more economically viable.

Of course, no one is saying, “hey, forget about diet and exercise, just take care of air pollution!” Nonetheless, even after controlling for factors such as genetics, income levels, weight, diet and exercise, Harvard researchers found a “consistent and significant” relationship between Type II diabetes prevalence and exposure to ultrafine particulate matter in a recent study.
