Abstract

Microplastics are emitted to the environment from many sources, and transported via water, soil and air. The airborne component is less well studied and measurements often focus on particles larger than 10 μm, while smaller particles are worse from a health perspective and likely more abundant. Measurement studies do often not include tyre wear, which is a large source of microplastics in urban areas. To improve the understanding of the microplastics concentration in urban areas, simulations of emissions and concentrations of atmospheric tyre wear particles (TWP) over Stockholm are performed. The results show that TWP are ubiquitous in urban areas, with highest concentrations along busy highways and in poorly ventilated street canyons. Yearly average roof level concentrations of TWP-PM10 range from 0.2 μg m−3 in areas with moderate traffic to 1.2 μg m−3 close to busy highways. Average yearly concentrations at three selected street canyons range from 0.7 to 1.1 μg m−3. The modelled concentrations correspond to 4–6% of the total measured PM10 concentration. TWP emissions are expected to increase with increasing traffic in future, and possibly also with the increase in vehicle weight with electric vehicles and SUV:s.

模拟城市环境中轮胎磨损的大气浓度
微塑料从许多来源排放到环境中,并通过水、土壤和空气进行运输。空气中的成分研究较少,测量通常集中在大于10μm的颗粒上,而从健康角度来看,较小的颗粒更差,可能更丰富。测量研究通常不包括轮胎磨损,轮胎磨损是城市地区微塑料的主要来源。为了更好地了解城市地区的微塑料浓度,对斯德哥尔摩上空的大气轮胎磨损颗粒物(TWP)的排放和浓度进行了模拟。结果表明,TWP在城市地区普遍存在,在繁忙的高速公路和通风不良的街道峡谷中浓度最高。TWP-PM10的年平均屋顶浓度范围从中等交通量地区的0.2μg m−3到繁忙公路附近的1.2μg m–3。三个选定街道峡谷的年平均浓度范围为0.7至1.1μg m−3。模拟浓度相当于总测量PM10浓度的4-6%。TWP排放量预计将随着未来交通量的增加而增加,电动汽车和SUV的车辆重量也可能增加。
