Summary
Recent news has highlighted the extent of aerosol pollution globally; cities with populations of millions are particularly at risk from high pollution events, leading to an increased risk of detrimental health effects. Mega-cities, such as Beijing are particularly susceptible to the detrimental effects of high pollution effects. This study examines the organic aerosol from a winter campaign in Beijing using hourly filter samples analysed by UPLC coupled with high-resolution orbitrap MS and automated identification against a compound database. The aim of this study is to investigate the evolution of aerosol compounds in more detail; analysing co-variance of compounds with common tracer compounds and gas-phase measurements to establish source apportionment.

The Aerosol Society recognises the importance of our diverse community and believe that to produce the best quality science we must encourage a proactive and inclusive approach to equality. This can be achieved by developing and retaining a diverse range of talented people to achieve their full potential free from discrimination. We acknowledge our role in engaging with the wider aerosol science community to develop a fair and friendly environment by promoting equality, diversity and inclusion for all, recognising that we come from varying backgrounds and experiences.
