They're called ultrafine particles.
A thousand times thinner than a strand of hair, ultrafine particles (#UFPs) are emitted by vehicles and industrial activity — and according to a recent study led by researchers at McGill University in Montreal, contribute to more than 1,000 premature deaths a year in that city and Toronto.”
