We all know plastics are clogging up our oceans, but what are they actually doing to the inside of our bodies? 

Headlines frequently warn that everyday plastics are invading human organs, harming our livers, and worsening health. But how much of that is solid science, and how much is hype? Brent is joined by leading microplastics researcher Dr Cassandra Rauert from the Queensland Alliance for Environmental Health Sciences at the University of Queensland. She separates fact from fiction, explaining why finding plastics in human tissue is far more complex than the headlines suggest.

• The Analytical Trap: How advanced laboratory techniques can easily misinterpret normal body fats (lipids) as polyethylene, leading to potential false positives in human tissue samples.

• Challenging the Narrative: Why robust data confirming high levels of polyethylene inside the human body remains scarce, and how contamination risks have clouded early research.

• Particles vs. Chemical Additives: Examining where the science genuinely stands regarding physical microplastic particles versus the potentially harmful chemical additives hidden within them.

• A Science-Backed Perspective: Practical, sensible ways for everyday listeners to look at environmental exposure without falling for sensationalized panic.

If you want to look past the media hype and understand the real, cutting-edge science of microplastics, this is a must-listen.
