AIR QUALITY AND HEALTH IMPACT OF PRIMARY SEMI-VOLATILE AND SECONDARY PARTICLES AND THEIR ABATEMENT

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，减少排放并减轻其对环境和健康的影响。极细颗粒的排放和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，即使在它们的大气行为方面存在重大知识缺口（例如，造成雾霾的机制/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，将提出技术和立法监测/减少机制来控制这些排放，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，在道路和实验室的实际驾驶排放（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；-利用先进仪器（例如小至1纳米的粒子）、方法和模型，描述二次气溶胶的形成和大气演化机制，以提供前体作用的科学证据；-根据对健康的影响（通过体外/体内测试）、环境/社会生命周期评估和风险对初级和次级排放化合物进行分类（“分类”）和确定优先次序（在人工智能的协助下）。我们会向持份者和立法/决策者提供宣传资料，并提出建议，以改善标准/规例，从而改善空气质素。利益相关者和合作伙伴的支持将加速向更清洁和气候中性社会/经济的过渡。

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.
