Pollution can alter DNA?

No we’re not talking about nuclear radioactive leakages here. National Geographic is reporting that a study concluded DNA may be damaged by breathing in particulate matter for an extended period of time:

Breathing in polluted air may wreak havoc on our DNA, reprogramming genes in as few as three days and causing increased rates of cancer and other diseases.

So says a new study that tracked DNA damage in 63 steel-foundry workers in Brescia, Italy, who, under their normal factory conditions, were exposed to particulate matter.

In the study, the workers’ blood was sampled on the morning of the first day of their workweeks—before they were heavily exposed to the foundry’s air—and again a few days later.

Comparisons between the two samples revealed significant changes in the methylation of four genes that may suppress tumors, said Baccarelli, who presented his research May 17 at the International Conference of the American Thoracic Society in San Diego, California.
