Meeting 81 – Following The Science? Exposure Limits, Toxicology & Human Health

5th Online GASG Meeting

2nd December 2021

Due to the ongoing challenges presented by the pandemic, the final meeting of the year was again an online-only event. Speakers from the UK and US  provided a wide ranging assessment of the health hazards arising from various gases and particulates, and issues associated with setting and enforcing appropriate exposure limits were also explored.

After considering the range of gases which are important in human biological processes, the human respiratory system was considered in more detail, focussing in particular on the importance of oxygen reactivity and the negative implications this can have. The direct relationship between air pollution and respiratory health & cognition was explained, and other implications for long term effects were also raised.

Although this topic now regularly features in mainstream media, there are still many areas requiring urgent scientific research to support air quality improvement initiatives. The meeting was a timely update on key areas and the needs and opportunities for further study.
