Air pollution is a major risk for cardiovascular disease

22 July 2020

Long-term exposure to fine particulate outdoor air pollution is a major contributor to cardiovascular disease (CVD) and death, regardless of country income, a global study reveals.

But even small reductions in pollution levels can lead to a reduction in disease risk, say researchers in The Lancet Planetary Health.

‘Before this study, we were not sure if this was the case,’ said lead author from Oregon University Perry Hystad. ‘Some studies suggested that at high concentration, as seen in many developing countries, levels would have to be reduced by very large amounts before health benefits would occur.’
