Plastic Chemicals - A Toxic Relationship and How We Can Start Fixing It

Plastic Chemicals - A Toxic Relationship and How We Can Start Fixing It

Author: Anja Krieger September 24, 2025 Duration: 41:55
In this episode, we’re taking a deep dive into plastic chemicals and their impacts on human and environmental health. You’ll learn why it’s not such a great idea to put plastic containers into your dishwasher, and why fatty food is especially prone to absorbing chemicals from food packaging. We’re also discussing a common and mostly misunderstood mantra of toxicology, the claim that it’s always the dose that makes the poison. Well, it turns out, that that’s not always true. We’re looking at how some chemicals in plastics can hack our hormone systems, how the political regulation of chemicals is not sufficient, and what we can do about it. In short, we’re taking a look at our toxic relationship with plastics and chemicals, why it affects some people more thana others, and how we can start fixing it. My guests are Martin Wagner, Professor of Biology at the Norwegian University of Science and Technology NTNU, and Jane Muncke,  Managing Director and Chief Scientific Officer at the Food Packaging Forum. We met on the sidelines of the plastics treaty negotiations in Geneva a month ago.

Anja Krieger hosts Plastisphere: A podcast on plastic pollution in the environment, a series that digs into the complex story of synthetic polymers. This isn't just a catalog of environmental damage, though that reality is confronted directly. Instead, the podcast carefully examines how these materials, foundational to contemporary life, now permeate every corner of the natural world and our own bodies. Anja guides listeners through a nuanced exploration, asking whether a sustainable coexistence is even possible. She doesn't provide easy answers but facilitates necessary conversations, bringing together researchers, activists, industry insiders, and communities on the front lines. Each episode is built on specific stories and scientific insights, moving from the deep ocean to human bloodstreams to policy halls. You'll hear about the chemistry of plastics, their journey as waste, and the cultural and economic systems that perpetuate their use. The strength of this podcast lies in its commitment to presenting a genuine spectrum of perspectives, avoiding simple blame in favor of understanding a truly global dilemma. It’s a thoughtful, sometimes surprising, and always human-centered look at one of the most defining material challenges of our time.
