摘要：Graphical abstractDisplay OmittedHighlights•Effect of ambient environmental conditions on nanoparticle from road traffic.•Weakness and strengths of nanoparticle analytical protocols.•Nanoparticles effect on human health, environment and climate.•Alternatives to increase sustainability in vehicular traffic.AbstractHuman effects and environment impacts associated with nanoparticles generated from road traffic have recently attracted wide attention. Knowledge of the influencing variables on both number and mass of nanoparticles, sources, characteristics and limitations of advanced commercially accessible instruments for monitoring nanoparticles, are still scarce and not sufficient to make regulatory decision on solid particles smaller than 23 nm (SPN < 23 nm). Given the harmful effects of nanoparticles on human health (i. e. visibility impairment, cardiac-rhythm disturbance, heart attacks, premature death, etc.), their control and assessment seem to be an absolute priority.In this overview, we classify and analyze the existing knowledge of nanoparticles in road traffic atmosphere, recent progress, and emerging priorities in research related to these topics. The major aspects of ongoing research in this field, and a brief discussion of the main sources of atmosphere nanoparticles are presented. The subsequent section focuses on the influencing parameters of nanoparticles including climate conditions, height above the road surface and distance between source (road traffic) and sampling site. The next section provides a comprehensive summary on sampling measurement methodologies and instrumental techniques. We also review the health and environment implications associated with particle exposure. Finally, an evaluation of the state of research related to nanoparticles together with highlights for future research activities are also presented.
