Human 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.

与道路交通产生的纳米颗粒相关的人类影响和环境影响最近引起了广泛关注。关于纳米粒子数量和质量的影响变量、来源、用于监测纳米粒子的先进商用仪器的特性和局限性的知识仍然缺乏，不足以对小于 23 nm (SPN < 23 nm) 的固体粒子做出监管决定. 鉴于纳米粒子对人类健康的有害影响（即能见度障碍、心律紊乱、心脏病发作、过早死亡等），它们的控制和评估似乎是绝对优先事项。

在本概述中，我们对道路交通大气中纳米粒子的现有知识、最新进展以及与这些主题相关的研究中出现的优先事项进行了分类和分析。介绍了该领域正在进行的研究的主要方面，并简要讨论了大气纳米粒子的主要来源。随后的部分重点介绍纳米粒子的影响参数，包括气候条件、路面高度以及源（道路交通）与采样点之间的距离。下一节对抽样测量方法和仪器技术进行了全面总结。我们还审查了与颗粒暴露相关的健康和环境影响。最后，
