The Exposure Scientist

We would love to hear what you think?Welcome to another episode of The Exposure Scientist Podcast! Today, host Dr. Alex LeBeau dives into the world of nontuberculosis mycobacterium (NTMs)—a large and diverse group of waterborne bacteria that pose health risks but are often overlooked. While Legionella gets most of the attention due to its national reportable status, NTMs are emerging as a significant concern for water systems in homes, workplaces, spas, and even healthcare settings.In this episode, you'll learn where NTMs are commonly found, why tracking and managing them can be so challenging, and how our current water safety strategies may be falling short. Dr. Alex LeBeau highlights real-world cases and industry guidelines while offering practical advice on considering NTMs in your facility’s water management plan. Whether you’re a concerned homeowner, a risk manager, or just curious about hidden hazards in your everyday environment, this episode sheds light on a topic that's quickly becoming crucial for public health. Stay tuned as we explain NTMs and how to protect yourself and others.Contact Dr. Alex LeBeau at Exposure Consulting for exposure litigation support or Exposure Science Consulting.

We would love to hear what you think?Welcome to The Exposure Scientist podcast, where we dive into the everyday hazards that surround us, separating fact from fear. In this episode, host Dr. Alex LeBeau revisits the ever-evolving topic of microplastics—tiny particles that have sparked growing concern both in research and in the public eye. Drawing on the latest updates, including a major report from the European Food Safety Authority, Dr. Alex LeBeau unpacks what recent findings really tell us about microplastics in food contact materials, the challenges scientists face in studying them, and why uncertainty still clouds the risks these materials may pose. If you're curious about what you’re exposed to, and what science does (or doesn’t) know about these invisible particles, this episode will help you navigate the facts, the data gaps, and the realistic conclusions.Contact Dr. Alex LeBeau at Exposure Consulting for exposure litigation support or Exposure Science Consulting.

We would love to hear what you think?Welcome to another episode of The Exposure Scientist Podcast with Dr. Alex LeBeau. Today, we're diving into a topic that's at the heart of the profession: branding and identity in exposure science and industrial hygiene. Dr. LeBeau takes us outside for a candid conversation about the ever-evolving field, exploring questions like, what exactly is industrial hygiene? How have roles and expectations shifted with attempts to rebrand the field as “occupational and environmental health and safety” (OEHS) professionals? And why do so many people—even those seeking help—struggle to understand what exposure scientists actually do?Through personal anecdotes and industry insights, Dr. LeBeau sheds light on the challenges exposure scientists face in defining their expertise, communicating their value outside their professional echo chamber, and ensuring the next generation grasps both the roots and the future of this vital work. Whether you’re a student, a fellow professional, or just curious about the field, this episode encourages us all to sharpen our "elevator pitch" and rethink how we tell the world who we are and what we do. So let’s get started—because understanding exposure science is more important than ever.Contact Dr. Alex LeBeau at Exposure Consulting for exposure litigation support or Exposure Science Consulting.
