The accumulation of persistent, polymeric wear particles in the atmosphere is an emerging public health issue. Commonly termed 'microplastic', this particle domain includes synthetic fibres from textiles, fragments from plastic articles and tyre wear emissions from road traffic. Inhalation exposure to elevated levels of inhalable and respirable microplastics has been linked to occupational lung disease1 and, recently, to upper airway irritation due to the shedding of polypropylene fibres from mask-wearing during the SARS-CoV-2 pandemic2. No legislation is in place to limit or reduce microplastic emissions and the proportion of polymeric wear particles in ambient particulate matter, e.g. from road traffic, has increased.This project aims to characterise the presence and quantity of microplastic aerosols in indoor and outdoor environments. It will do this by advancing measurement, using cutting-edge laboratory instrumentation to identify unique chemical tracers for microplastics from diverse urban sources and explore novel technologies for their measurement in the field. Light induced fluorescence (UVLIF) has previously been used to identify the presence of microplastics in tissue, by adapting algorithms used to classify bioaerosols it is hypothesised that the strong plastic fluorescent signature from microplastics will be detectable in ambient samples. This project brings together a team of supervisors with expertise in microplastics, atmospheric science and advanced data analytical tools. EPSRC areas: particle technology and biophysics

大气中持久性聚合物磨损颗粒的积累是一个新出现的公共卫生问题。这一颗粒领域通常被称为“微塑料”，包括纺织品中的合成纤维、塑料制品的碎片和道路交通产生的轮胎磨损排放物。吸入暴露于可吸入和可呼吸微塑料水平升高与职业性肺病有关，最近还与SARS-CoV-2大流行期间戴口罩导致聚丙烯纤维脱落导致上呼吸道刺激有关。没有立法来限制或减少微塑料的排放，聚合物磨损颗粒在环境颗粒物（例如道路交通颗粒物）中的比例有所增加。该项目旨在描述室内和室外环境中微塑料气溶胶的存在和数量。它将通过推进测量来实现这一目标，使用尖端的实验室仪器来识别来自不同城市来源的微塑料的独特化学示踪剂，并探索在现场测量微塑料的新技术。光诱导荧光（UVLIF）先前已被用于识别组织中微塑料的存在，通过调整用于分类生物气溶胶的算法，假设微塑料的强塑料荧光特征将在环境样品中检测到。该项目汇集了一个在微塑料、大气科学和先进数据分析工具方面具有专业知识的主管团队。EPSRC研究领域：粒子技术和生物物理学
