Last year, a study made startling headlines around the world with the claim that the average person carries the equivalent of a plastic teaspoon of microplastics in their brain. But how accurate is that finding, and if it’s questionable, why did the authors present it with such confidence? This week, we explore the challenges scientists face when measuring microplastics and nanoplastics in the human body, and why even peer-reviewed research published in the world’s most respected journals can sometimes get it wrong. Plus, are pumps on things like hand soap rubbish or not, does EPR penalise colour in plastic, and why is Robbie's window full of rubbish?Join hosts James Piper and Robbie Staniforth as they delve into the world of recycling, hopefully having fun along the way. One thing is for sure, they will talk absolute rubbish from start to finish.We would love you to join our community on DiscordSpecial thanks to our sponsor, EcosuretyTo get exclusive videos and clips, follow us on Instagram, TikTok, X, Threads or Facebook; @rubbishpodcast or YouTube: @talkingrubbishpodcastOr you can contact James and Robbie with questions or just general rubbish musings using the email address [email protected] or by texting them via WhatsApp on 07356 069 232Relevant links and reports mentioned in the programme can be found on the Talking Rubbish Linktr.eeTranscripts and episodes can be found on the Talking Rubbish websiteTimestamps:Why microplastics are so hard to measure - 1:35Additions and corrections - 27:45Rubbish or Not: pumps - 36:22Rubbish News - 41:06Does EPR penalise colour in plastic? - 46:20Residual Rubbish - 53:25 Music licence ID: 6WPY8Q4O2RPFIOTL
