Air passengers exposed to extremely high levels of ultrafine particle pollution, study finds

Levels during boarding and taxiing were far above those defined as high by the World Health Organization

Tiny and unregulated, ultrafine particles have the potential to cause major health problems

A thousand times thinner than a strand of hair, ultrafine particles are emitted by vehicles and industrial activity — and according to a recent study led by researchers at McGill University, contribute to more than 1,000 premature deaths a year in Montreal and Toronto.

Researchers tie 1,100 deaths to ultrafine particles

A new study from McGill University shows UFPs — primarily from vehicle emissions and industrial activities — are linked to approximately 1,100 premature deaths each year in Toronto and Montreal. About 600 of those fatalities occur in Toronto alone.

Ultrafine particles can change defense against lung cancer

While it may seem common knowledge that smoking is bad for your lungs, if and how ultrafine particles present in cigarette smoke impact the development and progression of lung cancer remains unclear. Researchers at Baylor College of Medicine sought to find how airborne ultrafine particles in smoke can change a host's defense against lung cancer.
