Considering the growing transport demand and dependence on oil, collective and immediate actions must be taken to abate emissions and mitigate their environmental and health impacts. Very fine particles emissions, and the formation of secondary aerosols through atmospheric processing, are believed to be the pollutant with the greatest public health impact, even if there is a major knowledge gap concerning their atmospheric behaviour (e.g. mechanism/contribution to smog episodes). AEROSOLS is a 36-months timely, ambitious, and interdisciplinary project with aim to define robust and transparent measurement and modelling methodologies to quantify the currently disregarded volatile/semi-volatile (V/S-V) primary and secondary emissions, and their associated risks. Furthermore, technological and legislative monitoring/abating mechanisms will be proposed to control these emissions in order to help improve air quality and public health. This will be achieved by: - quantifying V/S-V emissions formation, abatement, and dynamics within the vehicle system under real-driving-emissions (RDE) testing conditions on roads and in labs utilising innovative instrumentations and methodologies; - characterising secondary aerosol formation and atmospheric evolution mechanisms employing advanced instrumentations (e.g. for particles as small as 1nm), methodologies, and modelling to provide scientific evidence of the precursors’ role; - categorising (‘taxonomising’) and prioritising (assisted by Artificial Intelligence) primary and secondary emissions compounds based on their health impact (by employing in vitro/vivo testing), environmental/social life-cycle-assessment, and risk. Advocacy information will be provided to the stakeholders and legislation/policy makers and proposals will be made for improving the standards/regulations, and consequently the air quality. The support of stakeholders and partners will accelerate the transition to a cleaner and climate-neutral society/economy.

考虑到不断增长的运输需求和对石油的依赖，必须采取集体和即时行动来减轻排放并减轻其环境和健康的影响。人们认为，非常细的颗粒排放，以及通过大气加工形成二次气溶胶，被认为是具有最大公共卫生影响的污染物，即使存在有关其大气行为的主要知识差距（例如机制/对烟雾事件的贡献）。气溶胶是一个及时，雄心勃勃且跨学科的项目，旨在定义稳健和透明的测量和建模方法，以量化当前无视的挥发性/半挥发性（v/s-v）原发性和次要排放量，及其相关风险。此外，将提出技术和立法监测/减轻机制来控制这些排放，以帮助改善空气质量和公共卫生。这将通过以下方式来实现： - 在实地驾驶排放（RDE）测试条件下，使用创新仪器和方法在实验室测试条件下，量化车辆系统内的V/S-V排放构成，减排和动态； - 表征采用高级仪器（例如，对于小至1NM的颗粒）的次级气溶胶形成和大气进化机制，方法和建模，以提供前体作用的科学证据； - 根据其健康影响（通过使用体外/体内测试），环境/社会生命周期评估和风险，对（人工智能的“分类”）进行分类（“分类”）和优先级（在人工智能的协助下）。倡导信息将提供给利益相关者，立法/政策制定者，并将提出提案，以改善标准/法规，从而提高空气质量。利益相关者和合作伙伴的支持将加速向更清洁，气候中性社会/经济的过渡。
