The World Health Organisation (WHO) describes poor air quality as the largest single environmental health risk and attributes 8 million deaths annually to the consequences of exposure to air pollution. Vietnam is one of the fastest growing economies in SE Asia and, as a result, has undergone rapid urbanisation, industrialisation and population growth. This has led to the deterioration of, amongst other factors, air quality, with Vietnam being one of the most polluted countries in the world, ranked 170th out of 180 countries for air quality in a recent survey (Environmental Performance Index, Yale University, 2016). Air quality monitoring in Vietnam is patchy and many of the previously-reported studies are now quite dated. Given the rapid economic development and the growth of cities such as Ho Chi Minh City and Hanoi, there is a pressing need for new, up-to-date air quality measurements and a reassessment of the major sources of the observed pollution.For this study we propose to make measurements of a range of air quality indicators in the 2 largest cities in Vietnam, Ho Chi Minh City in the south and Hanoi in the north in order to improve our understanding of the concentrations and sources of air pollution in these contrasting environments. Measurements will be made during both the dry and wet seasons when the prevailing winds and likely sources of pollution could be quite different. The UK groups will take a range of analytical equipment to Vietnam which will complement the existing measurements made by the Vietnam partners. These instruments will vastly improve the speciation of measurements currently available, including detailed information on the organic compounds found in both the gas and particulate phase, the latter using novel mass spectrometric detection techniques. This will provide us with significantly enhanced datasets of both gas phase and particulate species which will allow us to better identify the key pollutants for human health and the relative importance of different emissions sources in the 2 cities using various data analysis tools including positive matrix factorisation (PMF).An important component of the project will be knowledge exchange and capacity building with the Vietnamese partners. This will include the hosting of Vietnamese staff in the UK for several months to learn techniques including particle filter analysis, air sensor technology and the use of source apportionment software such as PMF.The resultant air pollution database will be the largest and most comprehensive in Vietnam to date and will serve as a valuable resource for future air quality modelling studies, the verification of emission inventories and for the design of effective abatement strategies. To disseminate our findings we will organise a workshop in Vietnam towards the end of the project to which we will invite representatives from various academic, governmental and non-governmental organisations.

世界卫生组织 (WHO) 将不良空气质量描述为最大的单一环境健康风险，并将每年 800 万人的死亡归因于暴露于空气污染的后果。越南是东南亚增长最快的经济体之一，因此经历了快速的城市化、工业化和人口增长。这导致空气质量等因素恶化，越南是世界上污染最严重的国家之一，在最近的一项调查中，空气质量在 180 个国家中排名第 170 位（耶鲁大学环境绩效指数，2016 年） ）。越南的空气质量监测并不完善，之前报道的许多研究现在都已经过时了。鉴于经济的快速发展以及胡志明市和河内等城市的发展，迫切需要新的、最新的空气质量测量以及对观测到的主要污染源的重新评估。我们建议对越南最大的两个城市（南部的胡志明市和北部的河内）进行一系列空气质量指标测量，以加深我们对这些对比环境中空气污染浓度和来源的了解。测量将在旱季和雨季进行，当时的盛行风和可能的污染源可能有很大不同。英国团体将向越南运送一系列分析设备，这将补充越南合作伙伴进行的现有测量。这些仪器将极大地改善目前可用的测量形态，包括气相和颗粒相中发现的有机化合物的详细信息，后者使用新颖的质谱检测技术。这将为我们提供显着增强的气相和颗粒物数据集，使我们能够使用各种数据分析工具（包括正矩阵分解）更好地识别对人类健康有利的关键污染物以及两个城市不同排放源的相对重要性（ PMF）。该项目的一个重要组成部分是与越南合作伙伴的知识交流和能力建设。这将包括在英国接待越南员工几个月，学习颗粒过滤器分析、空气传感器技术以及PMF等源解析软件的使用等技术。由此产生的空气污染数据库将是越南最大、最全面的空气污染数据库迄今为止，并将成为未来空气质量建模研究、排放清单核查和有效减排策略设计的宝贵资源。为了传播我们的研究结果，我们将在项目结束时在越南组织一次研讨会，我们将邀请来自各个学术、政府和非政府组织的代表参加。
