The proportion of harmful substances in particulate matter is much higher than assumed

People breathing contaminated air over the course of years are at greater risk of developing numerous diseases. This is thought to be due to highly reactive components in particulate matter, which affect biological processes in the body. However, researchers have now shown that precisely these components disappear within hours and that previous measurements therefore completely underestimate the quantities in which they are present.
