New Evidence of Ozone and Pollution and Heart Attacks

French researchers have reported that short-term ozone exposure within a period of 1 to 2 days is related to acute coronary events in middle-aged adults without heart disease, and that nitrogen dioxide and sulfur dioxide are not.

The study design allowed for control of long-term seasonal trends, and adjusted for temperature, relative humidity, and influenza epidemics.
