加拿大最大的城市每年有1 100人过早死亡,这与无管制的空气污染物UFP有关,主要是汽车排放和工业活动造成的。 1,100 premature deaths annually in Canada's largest cities linked to unregulated air pollutant UFPs, primarily from vehicle emissions and industrial activities.

McGill领导的研究人员进行的一项研究将加拿大最大城市每年约1 100例过早死亡与一种无管制的空气污染物 -- -- 超松粒子(UFPs)联系起来。 A study by McGill-led researchers links about 1,100 premature deaths annually in Canada's largest cities to ultrafine particles (UFPs), an unregulated air pollutant. UFP 主要来自车辆尾气排放和工业活动，长期暴露与非意外死亡风险增加 7.3% 有关。 UFPs primarily come from vehicle emissions and industrial activities, and long-term exposure is associated with a 7.3% increase in non-accidental death risk. 随着城市地区的发展,该研究呼吁针对UFP采取监管行动. The study calls for regulatory actions targeting UFPs as urban areas grow.
