Sources and Effects of PM2.5 - Defra, UK

The biggest impact of particulate air pollution on public health is understood to be from long-term exposure to PM 2.5, which increases the age-specific mortality risk, particularly from cardiovascular causes. Several plausible mechanisms for this effect on mortality have been proposed, although it is not yet clear which is the most important. Exposure to high concentrations of PM (e.g. during ...
