How Forever Chemicals Affect the Climate
In recent years, forever chemicals have gained a lot of attention. They’re man-made substances that are known as per- and polyfluoroalkyl substances (PFAS). What started out as an ingenious way to create water- and grease-resistant products has morphed into one of the most dangerous pollutants.
What are Forever Chemicals?
Even though forever chemicals are still used in many industries, they’re recognized as a root cause for public health concerns, and environmental and climate damage. Let’s delve more into these toxic chemicals, and see why we should be avoiding them at all cost.
What Are PFAS Chemicals?
PFAS is a broad class of chemicals that includes over 4,000 different compounds. They’ve been used since the 1940s in various consumer products due to their unique ability to repel water, grease, and oil.
Although the forever chemicals list is long, we primarily see them in non-stick cookware, water resistant clothing, stain-resistant fabrics, firefighting foams, and food packaging materials.
The chemical structure of PFAS is a carbon-fluorine bond, one of the strongest bonds in organic chemistry. This is what creates its resistance to water, heat, and oil. At the same time, it’s also what makes them dangerously persistent in the environment.
Why Are They Called Forever Chemicals?
PFAS have an extreme resistance to the natural degradation process. Unlike other chemicals that will eventually break down over time, PFAS have remained unchanged for decades, if not centuries.
Their carbon-fluorine bonds make them resistant to natural processes that typically break down other compounds like sunlight, bacteria, and chemical reactions. As a result, they accumulate in the environment, leading to widespread contamination. This includes soil, water, and air.
Environmental Impact of PFAS
The environmental impact of PFAS is profound and far-reaching. It’s never a good sign when we find forever chemicals in water bodies or soil. Astoundingly, they’ve also been found in remote areas like the Arctic, demonstrating their ability to spread across the globe.
Their persistence means they’ll also be absorbed by plants, animals, and, eventually, humans. Sadly, PFAS have been found in drinking water supplies all over the world, affecting millions of people’s lives.
Due to their chemical stability, conventional water treatment processes are often ineffective at removing these dangerous chemicals once they enter a water supply.
This sort of contamination also affects our wildlife populations. Fish can accumulate PSAS in their tissues, leading to bioaccumulation up the food chain. When we consume contaminated fish, we, too, may be exposed to higher concentrations of PFAS.
Regulatory Challenges of PFAS
Despite the mountain of evidence against these complex compounds, regulatory efforts to mitigate their danger have been slow and inconsistent. One of the biggest challenges to overcome is the sheer number of compounds within the class. Each one has its own properties and potential risks.
The Environmental Protection Agency (EPA) has taken a stand, however, setting health advisories for certain PFAS compounds in drinking water. It’s working towards establishing enforceable limits. As for our part, the best we can do is engage in cleanup efforts and continue to educate the public wherever possible.
Let’s Continue to Protect Our Environment and Climate
The alarming truth about forever chemicals represents a significant threat to the environment, as well as human, animal, and plant life. Their continued and widespread use will continue to lead to global contamination, with potentially devastating consequences to our health and climate.
