“Forever chemicals,” widely used in everyday consumer products, are linked to cancer, brain damage, thyroid disease, low birth weights, obesity, infertility, hormone suppression and other health issues.

Home gardeners who buy “natural” fertilizers may be exposing themselves to toxic “forever chemicals” linked to cancer, brain damage and other health problems, The Guardian reported.
Lab analysis commissioned by Sierra Club and Ecology Center of Michigan found per- and polyfluoroalkyl (PFAS) chemicals in all nine samples of biosludge home fertilizers sent for testing. Eight of the nine bags contained levels that exceeded screening levels set by the state of Maine.
The products, marketed as “eco” or “natural,” were sold at stores such as Home Depot, Lowes, Menards and Ace Hardware.
Biosludge, or biosolids, are a mix of human feces, industrial chemicals and pharmaceutical drugs that have been “lightly treated” by wastewater treatment plants, repackaged and sold as home fertilizer.
The latest findings sparked concerns about the risks of applying fertilizer containing PFAS to food crops.
Gillian Miller, senior scientist with the Ecology Center, told The Guardian:
“Spreading biosolids or sewage sludge where we grow food means some PFAS will get in the soil, some will be taken up by plants, and if the plants are eaten, then that’s a direct route into the body.”
‘Forever chemicals’ accumulate in humans
PFAS, also known as “forever chemicals” due to their persistence in humans in nature — meaning they don’t break down and can accumulate over time — are toxic to humans.
Studies link the chemicals to kidney and testicular cancer, high cholesterol, high blood pressure, pre-eclampsia in pregnant women, low birth weights and decreased vaccine response in children. The chemicals may also cause thyroid disease, obesity, reduced fertility and hormone suppression.
PFAS make their way into biosludge when industries that use the chemicals to make products resistant to water, stain and grease dump the chemicals into public sewer systems. PFAS and other industrial chemicals end up at wastewater treatment plants where they’re combined with human waste and made into semi-solid sludge.
In addition to being sold for residential use, biosludge is also applied to farmland, forests, parks and golf courses, a practice some say is causing health problems.
According to the Guardian:
“Spreading pollutant-filled biosolids on farmland is making people sick, contaminating drinking water and filling crops, livestock and humans with everything from pharmaceuticals to PFAS.”
