When I walk through the loading docks of our warehouse every day, I see pallets of chemicals labeled for everything from agricultural fertilizers to industrial water treatment. For years, I\u2019ve thought of those products as tools\u2014essential for keeping farms productive, factories running, and communities supplied with clean water. It wasn\u2019t until a decade ago, when my own niece was diagnosed with a thyroid disorder as a teenager, that I started asking a question I\u2019d never considered before: how do these chemicals actually interact with the human body\u2019s most complex regulatory system? The endocrine system, that quiet network of glands, hormones, and receptors that controls everything from metabolism to reproductive health, is a delicate balance. And what we put into the environment, often ends up finding its way back to us. Chemicals<\/a><\/p>\n

<\/p>\n

Let\u2019s start with the basics. The endocrine system works like a sophisticated messaging network: glands secrete hormones into the bloodstream, and those hormones bind to specific receptors in cells, triggering responses that regulate growth, mood, fertility, and even how our bodies process sugar. For this system to function correctly, every hormone needs to hit its target at the right time, in the right amount. That\u2019s where endocrine-disrupting chemicals (EDCs) come in\u2014they\u2019re foreign substances that can mimic, block, or interfere with these natural messengers in ways that throw the whole system off. A lot of people think EDCs are only from plastics or pesticides, but as a chemical supplier, I know our industry is part of a much larger supply chain that these chemicals flow through. What I want to make clear here is that not every chemical we manufacture is an EDC, and not all exposure is dangerous. The key is understanding which ones pose risks, and how we can handle them responsibly.<\/p>\n

Take bisphenol A (BPA), for example. I remember when BPA was a staple in plastic water bottles and food packaging in the 1990s. Studies later found that BPA mimics estrogen, binding to estrogen receptors and altering hormone levels, even at very low doses that don\u2019t cause acute toxicity. That\u2019s the tricky part about EDCs: unlike many chemicals that cause obvious harm after a high exposure, EDCs can have subtle effects over time, or even affect developing fetuses and children, whose endocrine systems are still growing. We stopped supplying BPA for food contact products around 2015, after we saw the research and worked with our manufacturing partners to source alternative bisphenols that are less disruptive. But BPA isn\u2019t the only one. Phthalates, which we use as plasticizers in some industrial coatings and flexible packaging, are another EDC. They interfere with testosterone production, and long-term exposure has been linked to reproductive issues in men and developmental delays in young boys.<\/p>\n

Another group that\u2019s been in the news is organophosphate pesticides. Wait, but let\u2019s be clear: I supply some organophosphates for agricultural use, and they\u2019re effective at controlling pests that destroy crops and feed millions of people around the world. The problem isn\u2019t the chemical itself, it\u2019s how it\u2019s applied, how it runs off into water systems, and how residues end up on fresh produce. Organophosphates don\u2019t just affect pest nervous systems\u2014they can also disrupt thyroid function in humans, especially in pregnant women. A 2021 study in Environmental Health Perspectives found that women with higher levels of organophosphate residues in their urine were more likely to have lower thyroid hormone levels during pregnancy, which is critical for fetal brain development. That\u2019s the kind of research that changed how our company approaches product stewardship. We started working with farmers to develop better application practices, like timed spraying that reduces runoff, and we\u2019ve invested in testing methods to measure trace residues so we can track where our chemicals end up in the environment.<\/p>\n

What many people don\u2019t realize is that endocrine disruption isn\u2019t just about big, obvious health issues. It\u2019s also about the small, cumulative effects that add up over a lifetime. For instance, common industrial chemicals like per- and polyfluoroalkyl substances (PFAS), which we used to supply for waterproof coatings and firefighting foams, have been linked to decreased insulin sensitivity, which can lead to type 2 diabetes, and altered thyroid function. PFAS are persistent, meaning they don\u2019t break down in the environment\u2014so they can build up in soil, water, and even our bodies over time. That\u2019s why a few years ago, our company made the decision to phase out all PFAS products not required for critical industrial applications. We worked with our R&D team to develop alternative coatings that are just as effective, without the persistent EDC properties. It wasn\u2019t cheap, and some customers were resistant at first, but more and more, they\u2019re coming around because they recognize that sustainability and responsible chemical use aren\u2019t just buzzwords\u2014they\u2019re good for business, too.<\/p>\n

Let\u2019s talk about how exposure happens, because that\u2019s a big part of the picture. Chemicals don\u2019t just float in the air and hit you directly. They can leach from plastic containers into food and drinks, run off from fields into rivers and drinking water, be released into the air from factory emissions, or even transfer through dust in our homes. For children, exposure is even higher because they spend more time on the floor, touching things, and putting their hands in their mouths. A 2019 report from the Endocrine Society found that more than 90% of people in the U.S. have detectable levels of at least one EDC in their blood or urine, and children have even higher levels. That statistic stuck with me because it\u2019s personal\u2014my niece, who I mentioned earlier, was tested for multiple EDCs, and her levels were above the average for her age. It doesn\u2019t mean those levels caused her thyroid disorder, but it does mean that we as a society are exposed to these chemicals every day, and we need to be more intentional about controlling where they come from.<\/p>\n

Now, as a chemical supplier, I\u2019m not here to make excuses for harmful products. But I also want to set the record straight: chemicals are necessary for modern life. We can\u2019t feed the global population without agricultural chemicals that protect crops. We can\u2019t build the infrastructure, manufacture the electronics, or provide the water treatment services that people rely on without industrial chemicals. The problem isn\u2019t the chemicals themselves\u2014it\u2019s how we\u2019ve managed them in the past, often without full understanding of their long-term effects on the endocrine system. That\u2019s why our company has implemented a rigorous product testing program before any new chemical leaves our warehouse. We work with independent third-party labs to screen for EDC properties, test for endocrine disruption in cell models, and even partner with universities to study how our chemicals interact with living organisms. We also track every shipment from our facility to its final destination, so we can trace if a chemical is ending up in areas where it might pose a risk.<\/p>\n

Another point that\u2019s often missed: the dose makes the poison, but for EDCs, the \u201csafe\u201d level isn\u2019t zero. Traditional toxicology used to assume that if a chemical didn\u2019t cause acute harm at a certain dose, it was safe. But research over the last 20 years has shown that EDCs can have effects at doses much lower than those that cause toxicity. For example, a 2018 study on atrazine, an herbicide we supply for weed control in corn and soy crops, found that at levels below the U.S. Environmental Protection Agency\u2019s (EPA) \u201csafe\u201d limit, atrazine can alter estrogen signaling in frog populations, leading to abnormal reproductive development. That same effect has been observed in human cell studies. So we\u2019ve worked with our agricultural customers to adjust application rates, so that atrazine residues in water systems stay well below even the low levels where endocrine disruption is a concern. We also provide training to farmers on how to store and dispose of unused herbicides, to prevent them from leaching into groundwater.<\/p>\n

What really drives me is that we have a responsibility, as suppliers, to be part of the solution, not just part of the problem. A few years ago, we launched a product stewardship initiative where we work with customers from the first stage of a project, to help them choose chemicals that meet their needs without posing endocrine risks. For example, if a food packaging manufacturer used to order plasticizers that are phthalates, we\u2019d show them our alternative line of phthalate-free plasticizers that work just as well, and help them test those alternatives to make sure they\u2019re safe. We also partner with local environmental groups to test water sources near our warehouses, so we can track if any of our chemicals are entering the environment and take action immediately if they are. It\u2019s not just good for our reputation\u2014it\u2019s the right thing to do.<\/p>\n

Of course, there are still challenges. Some EDCs are in products that we rely on every day, and there\u2019s no simple alternative. For example, some specialized industrial lubricants that we supply for heavy machinery have chemical properties that could disrupt the thyroid. We\u2019re still working with our R&D team to find alternatives that perform the same function, without the endocrine risks. It\u2019s a slow process, and it requires investment, but it\u2019s worth it. We know that if we can\u2019t find an alternative, we have to be extra careful in how we handle, transport, and dispose of that chemical, to minimize any chance of exposure to humans or the environment.<\/p>\n

I also want to address a common misconception: that all natural chemicals are safe, and all synthetic chemicals are dangerous. That\u2019s not true. Some natural chemicals, like some phytoestrogens in soy and flaxseed, can also mimic estrogen, though the human body handles them differently at normal consumption levels. And some synthetic chemicals, like certain biodegradable solvents we supply for cleaning products, have no endocrine-disrupting properties at all. The key is not whether a chemical is natural or synthetic, but what it does to the endocrine system, and how we manage its use.<\/p>\n

Back to my niece, who is now a college student studying environmental science. She still has to take medication for her thyroid, but she\u2019s also been part of our company\u2019s community outreach program, where we test local residents for EDC awareness and help them reduce their exposure. When she told me that her experience inspired her to work on chemical safety, I knew that the work we\u2019re doing as a supplier isn\u2019t just about moving products from one place to another. It\u2019s about protecting the next generation, so that children grow up with healthy endocrine systems, able to thrive.<\/p>\n

<\/p>\n

At the end of the day, the chemicals industry has a unique role to play in this conversation. We\u2019re not just manufacturers\u2014we\u2019re partners, researchers, and stewards. We can choose to hide behind old regulations that don\u2019t account for the latest endocrine research, or we can lead the way in developing safer products, better practices, and transparency for our customers and the public. If you\u2019re a business owner, a farmer, or a professional who works with chemicals and wants to learn more about how to avoid endocrine-disrupting options, or how to implement better safety measures, we\u2019re here to help. We can walk you through our product lines, share our research data, and work with you to find solutions that meet your needs without compromising health or the environment. Reach out to our team to connect for a conversation about responsible chemical use and how we can collaborate to make a difference.<\/p>\n
