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

大气中持续的，聚合物磨损颗粒的积累是一个新兴的公共卫生问题。该粒子结构域通常称为“微塑料”，包括来自纺织品的合成纤维，塑料物品的碎片和轮胎磨损道路交通的排放。吸入暴露于吸入和可呼吸的微塑料水平升高与职业肺病有关，最近由于SARS-COV-2 PANDEMATIC2中戴面膜的聚丙烯纤维脱落而与上呼吸道刺激有关。没有立法来限制或减少微塑料排放，并且在环境颗粒物中，聚合物磨损颗粒的比例，例如从道路交通中，该项目旨在表征室内和室外环境中微型气溶胶的存在和数量。它将通过进行测量，使用尖端的实验室仪器来确定来自各种城市来源的微塑料的独特化学示踪剂，并探索新型技术以在现场进行测量。通过适应用于对生物溶质溶剂进行分类的算法，光感应荧光（UVLIF）先前已用于鉴定组织中微塑料的存在，可以假设在环境样品中可以检测到来自微塑料的强塑性荧光特征。该项目汇集了一个主管团队，具有微塑料，大气科学和高级数据分析工具方面的专业知识。 EPSRC领域：粒子技术和生物物理学
