In this episode we discuss air quality and the consequences of air pollution with Professor Sir Stephen Holgate, Clinical Professor of Immunopharmacology, and Doctor Natasha Easton, Air Quality Researcher and Specialist Policy Officer for the Faculty of Environmental and Life Sciences.
Their engaging conversation explores the major steps taken so far to mitigate the acute effects of air pollution, as well as ongoing concerns related to long-term, life-course exposure and its role in accelerating disease and inflammatory processes. Nat also highlights the risks posed by this largely invisible form of pollution, which she brought to the attention of the Environmental Audit Committee in December 2025, subsequently securing a new Parliamentary Inquiry into air pollution.
Stephen and Nat discuss emerging research frontiers, including ultrafine particles, non-exhaust emissions, indoor air pollutants, and findings from a recent study on port emissions. They also mention potential developments in air quality monitoring systems in the Southampton area. In addition, they address issues of inequity, examining how poor air quality disproportionately affects disadvantaged communities, and outline key recommendations for urban design.
This is a particularly rich episode, in which our guests share their expertise to inform and empower the public, as well as stakeholders involved in raising awareness and shaping policy on air quality and environmental change. A central theme of the discussion is how to engage effectively with policymakers, combining academic research with public policy engagement to generate meaningful impact. The episode also emphasises the importance of early collaboration, sustained engagement, and the development of strong storytelling and communication skills.
As Professor Sir Stephen Holgate reflects at the end of the episode: “It’s important not to let opportunities miss you by. There will always be opportunities along the way – whether it’s talking to school children or participating in science festivals. Whatever the particular opportunity, you can’t go wrong by having a go, because everybody fails at times. What you may consider as failure can often be viewed as success through another pair of spectacles. Don’t be afraid to go out there and project yourself and say it like you would like to say it because you will be surprised what impact it can make”.
