In various parts of the country, from Hawaii to Wisconsin and California to Michigan, wildlife populations are facing alarming declines and health issues.
Endangered sea turtles are producing fewer hatchlings, tree swallows are struggling to reproduce, and sea otters are succumbing to infectious diseases. Even bluegills and hooded seals are displaying distress signs, including thyroid problems and slowed swimming. The common thread linking these disparate locations, animals, and illnesses?
High exposure to per- and polyfluoroalkyl substances (PFAS), often called forever chemicals. These surprisingly common chemicals are found in everything from nonstick pans to pizza boxes, and sadly, they seep into our environment. Recent studies underscore how the harm reaches far beyond our homes, impacting wildlife in startling ways.
Recently, scientists have raised concerns about the alarming effects of PFAS on various species, from endangered sea turtles in Hawaii to alligators in North Carolina’s Cape Fear River. In this article, we’ll understand the extent of this issue and discuss how these chemicals are destroying the natural world around us.
How Does AFFF Play a Role?
AFFF, or aqueous film-forming foam, is a type of firefighting foam known for its ability to extinguish stubborn fires. With over 6,000 PFAS chemical compounds in commercial use, these chemicals are used in various products, from food packaging to waterproof coatings.
The problem is that AFFF contains PFAS, man-made chemicals, which are extremely persistent. Once AFFF is used, these chemicals contaminate the soil and water. Recent studies and the ongoing AFFF lawsuit update highlight the far-reaching consequences of this pollution. The primary concern is that PFAS contamination is far from a local issue. These chemicals defy easy breakdown, traveling on wind, tides, and even within rainwater.
Which means they’ve spread to remote parts of the planet and our communities. Scientists are finding PFAS in wildlife across the globe, from sea turtles struggling to hatch to polar bears with compromised hormonal systems. The widespread use of PFAS since the 1950s has led to their pervasive presence in the environment, with hotspots identified on every continent.
A recent study published in The Science of the Total Environment sheds light on the extensive reach of PFAS contamination, pinpointing wildlife exposure hotspots in the U.S., Europe, China, and Australia. Lead author David Andrews and his team, from the Environmental Working Group (EWG), compiled data from scientific journals to underscore the global threat posed by PFAS to wildlife.
The Impacts on Wildlife and Ecosystems
The detrimental effects of PFAS exposure on wildlife health are increasingly apparent.
While humans have long been recognized as susceptible to PFAS-related health issues, research on wildlife impacts is a relatively recent but growing field. PFAS contamination has been documented in diverse species, including polar bears, whales, birds, and freshwater turtles, even in remote regions far from the sources.
These chemicals pose several health risks to wildlife, including disruptions to reproductive functions, immune system suppression, liver damage, and developmental abnormalities. For example, in Hawaii and other places in the North Pacific, researchers have documented a significant decline in hatchlings being born from the nests of rare Hawksbill and green sea turtles.
In Wisconsin, some tree swallows are unable to reproduce, whereas in California, contagious diseases are widespread in southern sea otters. The harmful effects of PFAS go even deeper. In Michigan, bluegills have been observed swimming slower. Meanwhile, in the Arctic, a few hooded seals and their pups have thyroid issues, as well.
In North Carolina’s Cape Fear River, American alligators have been discovered with lesions and open, tainted wounds. The injuries are linked to their compromised immune systems due to PFAS exposure. The scope of the issue is alarming, as PFAS threatens over 600 species worldwide. This is especially concerning for those who are already rare or endangered.
PFAS and the Human-Wildlife Connection
It’s important to note that the implications of PFAS on wildlife are not isolated from their effects on human health. In fact, in an odd twist, humans are now serving as a “sentinel species” for PFAS exposure. Meaning, that researchers use the wildlife data to better understand the potential risk to human health.
Hundreds of peer-reviewed studies have already documented the myriad ways in which PFAS can harm human health, from causing cancer and reducing immunity to impairing fertility and triggering liver damage. And evidence suggests wildlife is similarly vulnerable to these toxic chemicals.
PFAS: A Legacy of Deceit and Inaction
The PFAS story is one of corporate deceit and regulatory inaction. Manufacturers like DuPont and 3M knew about the dangers of these chemicals for decades, yet they chose to keep this information hidden from the public.
In the 1950s, 3M discovered that PFAS can build up in blood, and in the 1960s, DuPont found evidence of liver, kidney, and spleen damage. Yet, according to TruLaw, these studies were never made public. Thus, allowing the continued widespread use of these “forever chemicals.”
Furthermore, as the consequences for human and wildlife health become clear, the need for action is more urgent than ever. While some countries have taken steps to ban or restrict certain PFAS compounds, the global regulation of these chemicals is nevertheless inadequate.
Frequently Asked Questions
Q1. Can PFAS be found in bottled water?
Yes, PFAS has been detected in some bottled water brands. While levels may be lower than in tap water from contaminated sources, this underscores the widespread presence of these chemicals. If you’re concerned, look for brands with third-party certification for PFAS removal, or consider a home filtration system.
Q2. Can I get a blood test for PFAS?
Yes, specialized labs offer PFAS blood testing. This can reveal your level of exposure to certain PFAS types. However, remember that science is still evolving on what different blood levels mean for long-term health. Consult your doctor if you’re concerned about your risk.
Q3: Besides drinking water, how else are humans exposed to PFAS?
Humans encounter PFAS through several routes. One way is through food. PFAS can be found in fish caught from contaminated water, produce grown with contaminated water, and livestock raised on contaminated land.
Additionally, consumer products remain a source of exposure. PFAS is still used in some stain-resistant carpets, waterproof outdoor gear, and cosmetics. Even dust in our homes and buildings can contain PFAS particles shed from older products, leading to continued exposure.
In conclusion, these forever chemicals in our environment are far from a remote problem. The effects of PFAS pollution may start subtly, perhaps harming the wildlife in your backyard, but this invisible threat has the potential to impact us all.
From the Arctic to the tropics, these chemicals have infiltrated ecosystems, harming countless species and disrupting the delicate balance of life. By working together to implement stronger regulations, clean up contaminated sites, and raise awareness of this critical issue, we can protect our wildlife and the natural habitats they depend on. The future of our planet’s biodiversity depends on our ability to confront the PFAS challenge head-on.
Let’s embrace this responsibility and take the necessary steps to safeguard the incredible diversity of life that calls our world home.
