Meliora: a podcast from the Sustainability & Resilience Institute
Welcome to the Green Gown Award winning Meliora Podcast from the Sustainability and Resilience Institute at the University of Southampton!
This podcast explores the greatest and most wicked problem that is sustainability, whilst looking at how we are collectively addressing this critical global challenge.
Sustainability needs to be addressed by understanding how the economy, society, culture, politics and environment intersect, and this is the focus that informs each episode of the Meliora podcast.
In each episode, host Professor Simon Kemp and guest hosts are joined by a variety of guests, including academics, students, staff, researchers, alumni, community groups and business leaders.
The aim of the podcast is to shine a light on the vast range of topics surrounding sustainability and to allow listeners to learn about the critical challenges we face, as well as how they can be part of the solution. We also ensure our fantastic students have the opportunity to share their brilliant work with the world.
Podcast host: Professor Simon Kemp, Deputy Director of the Sustainability & Resilience Institute, University of Southampton
Podcast editors: Jack Dinham, Ellie Howell, Mya Harvey, Lily Killner, Sophie Green, Libby Kale, School of Geography and Environmental Science, University of Southampton
Podcast communications: Tyler Domone-Hollands, Hannah Parish, Alexander Ayerst, Maya Stevens, University of Southampton

Adchaya Apputhurai (BSc Environmental Science) joins us to discuss her dissertation "A sparkling problem in our aquatic environments: A study on glitter pollution".
Despite being a prevalent microplastic of a highly complex structure, glitter is overlooked as a pollutant. This study links particle size, short-term biological impact, and sediment transport for red PET glitter. The commercially available glitter was split into three size fractions, then Artemia sp. were exposed to these for 72 hours and mobility was quantified in a sediment column experiment that simulated episodic rainfall. The results show that fine particle glitters are persistent, mobile, and carry potential for physical harm to organisms, making their exposure risk greater. It is argued that glitter should be explicitly considered in microplastic regulation and monitoring frameworks, whilst also bringing more awareness to the public about its harm. Consumers are encouraged to make active choices when buying items including glitter to prevent pollution of sensitive aquatic environments.
