Even a low level of exposure to particulate matter (PM10) can have a detrimental effect on the lungs, scientists have concluded.
An international research team, led by the University of Technology Sydney (UTS) and the Woolcock Institute of Medical Research (WIMR) in Australia, say the findings have implications for people living next to major traffic corridors, warning that residents should be aware of how it may affect their respiratory health.
The study, published in the American Journal of Physiology – Lung Cellular and Molecular Physiology (AJP-Lung), exposed mice to low levels of traffic-related PM10.
It found that after three weeks, the mice developed inflammation in their lungs as a direct result of their PM10 exposure.
