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.

考虑到日益增长的运输需求和对石油的依赖，必须立即采取集体行动减少排放，减轻其对环境和健康的影响。非常细的颗粒物排放，以及通过大气处理形成的二次气溶胶，被认为是对公众健康影响最大的污染物，即使对它们的大气行为存在重大认识差距(例如，造成雾霾事件的机制/贡献)。气溶胶是一个为期36个月的及时、雄心勃勃的跨学科项目，旨在确定可靠和透明的测量和建模方法，以量化目前被忽视的挥发性/半挥发性(V/S-V)一次和二次排放及其相关风险。此外，还将提出技术和立法监测/减少机制，以控制这些排放，以帮助改善空气质量和公众健康。这将通过以下方式实现：-利用创新的仪器和方法，在道路和实验室的真实驾驶排放(RDE)测试条件下，量化车辆系统内V/S-V排放的形成、减少和动态；-利用先进的仪器(例如，针对小至1纳米的颗粒)、方法和建模来表征二次气溶胶形成和大气演变机制，以提供前体作用的科学证据；-根据对健康的影响(通过采用体外/体内测试)、环境/社会生命周期评估和风险，对主要和次要排放化合物进行分类(“分类”)和优先排序(在人工智能的协助下)。将向利益攸关方和立法/政策制定者提供宣传信息，并将提出改进标准/法规的建议，从而改善空气质量。利益攸关方和合作伙伴的支持将加速向更清洁和气候中立的社会/经济过渡。
