GAQC | 大气颗粒物的毒性：已有证据和知识盲区

GAQC简介

全球大气质量对话（Global Air Quality Conversation，GAQC）是在教育部“高等学校学科创新引智计划”的资助下，由北京大学环境科学与工程学院主办的国际系列研讨会，主要包括四个主题：大气污染形成化学机制、大气监测与模拟、空气质量与气候变化以及大气污染的健康效应，针对每一主题邀请国际有影响力的专家做主题报告并就最新研究成果进行小规模讨论。项目旨在交流国际前沿研究成果、增强国际学术合作并为学生开拓国际视野和开发科研新思路。

嘉宾介绍

Frank Kelly，英国伦敦帝国理工学院公共健康系教授。他研究方向涵盖从毒理学到科学政策的空气污染研究，旨在解析与空气污染相关的健康问题的潜在机制、建立模型系统以获取环境颗粒物的氧化潜力。他主持了对伦敦城市空气的研究，包括建立“伦敦拥堵收费区”和“低排放区”的相关影响；研究了与颗粒物相关的金属和醌的毒性、柴油和生物柴油废气排放、木材烟雾以及暴露生物标志物的识别；以及包括早产儿、哮喘、囊性纤维化和肺移植患者在内的患者群体中的氧化剂和抗氧化剂比例。他还关注了环境微塑料的区分和潜在的健康影响。Kelly 教授发表了 380 多篇关于臭氧、二氧化氮和颗粒物污染的毒理学和健康影响的论文和书籍（作为作者或编辑），为世界卫生组织提供有关空气污染问题的政策支持。

讲座内容

1）主题讲座（19:00-20:00）：Toxicity of Airborne Particles: Established Evidence and Knowledge Gaps （线上线下同时进行） 

    Since air pollutants are difficult and expensive to control, a strong scientific underpinning to policies is needed to guide mitigation aimed at reducing the current burden on public health. Much of the evidence concerning hazard identification and risk quantification related to air pollution comes from epidemiological studies. This must be reinforced with mechanistic confirmation to infer causality. In this review, we focus on data generated from four contrasting sources of particulate air pollution that result in high population exposures and thus where there remains an unmet need to protect health: urban air pollution in developing megacities, household biomass combustion, wildfires and desert dust storms. Taking each in turn, appropriate measures to protect populations will involve advocating smart cities and addressing economic and behavioural barriers to sustained adoption of clean stoves and fuels. Like all natural hazards, wildfires and dust storms are a feature of the landscape that cannot be removed. However, many efforts from emission containment (land/fire management practices), exposure avoidance and identifying susceptible populations can be taken to prepare for air pollution episodes and ensure people are out of harm’s way when conditions are life-threatening. Communities residing in areas affected by unhealthy concentrations of any airborne particles will benefit from optimum communication via public awareness campaigns, designed to empower people to modify behaviour in a way that improves their health as well as the quality of the air they breathe.

  2）面对面访谈（20:00-20:15）：由我院BBP卓越环境国际班的本科生代表就学术研究的疑惑和思考与Frank Kelly进行面对面交流，并汇总相应的回答和感悟，发表在BBP·交流的栏目中（https://mp.weixin.qq.com/s/I8Ib9uJOA9f0K4BhBIgt-w）

 3）小组讨论（20:15-20:30）：基于《Global nature of airborne particle toxicity and health effects: a focus on megacities, wildfires, dust storms and residential biomass burning》的小组讨论（在环境大楼B112线下进行）
