AEROSOLS

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。极细颗粒物的排放以及通过大气处理形成的二次气溶胶被认为是对公共健康影响最大的污染物，即使在其大气行为方面存在重大知识空白（例如，烟雾事件的机制/贡献）。AEROSOLS是一个为期36个月的及时、雄心勃勃的跨学科项目，旨在定义稳健、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，我们亦会建议设立技术和立法监察/消减机制，以控制这些排放物，从而改善空气质素和公众健康。这将通过以下方式实现：- 在道路上和实验室中使用创新的仪器和方法，在实际驾驶排放（RDE）测试条件下量化车辆系统内的V/S-V排放形成、减少和动态;- 采用先进仪器描述二次气溶胶形成和大气演变机制（例如，小至1纳米的颗粒）、方法和建模，为前体的作用提供科学证据;- 根据其健康影响（通过采用体外/体内测试），环境/社会生命周期评估和风险，对一次和二次排放化合物进行分类（“分类”）和优先级排序（人工智能辅助）。将向利益攸关方和立法/政策制定者提供宣传信息，并提出改进标准/法规的建议，从而提高空气质量。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。

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.
