: Non-tailpipe emissions driven by springtime road dust in northern latitude communities is increasing in importance for air pollution control and improving our understanding of the health effects of chemical mixtures from particulate matter exposure. High-volume samples from a near-road site indicated that days affected by springtime road dust are substantively different from other days with respect to particulate matter mixture composition and meteorological drivers. The high load of trace elements in PM on high road dust days has important implications for the acute toxicity of inhaled air and subsequent health effects. The complex relationships between road dust and weather identified in this study may facilitate further research on the health effects of chemical mixtures related to road dust while also highlighting potential changes in this unique form of air pollution as the climate changes.
受北方社区春季道路灰尘驱动的非尾气排放，对于空气污染控制和改善我们对颗粒物暴露导致的化学混合物健康影响的理解，正变得越来越重要。来自近路地点的大容量样本表明，受春季道路灰尘影响的日子与其他日子在颗粒物混合物组成和气象驱动因素方面有很大的不同。在高道路灰尘日，PM 中痕量元素的高负荷对吸入空气的急性毒性和随后的健康影响有重要意义。本研究中确定的道路灰尘与天气之间的复杂关系，可能有助于进一步研究与道路灰尘有关的化学混合物对健康的影响，同时也突出了随着气候变化，这种独特形式的空气污染可能发生的变化。
