The biggest risk with toilet paper, however, is not your skin at all. Most health experts, including those at the EWG, observe that skin absorption of PFAS is very, very low. The big culprits in human exposure are contaminated drinking water and food packaging.
Therefore, while these chemicals are noted in the product, the risk level as a result of using the product is low. The problem lies in the environmental build-up. Since these PFAS do not degrade, they accumulate in our soil and water forever.
The bigger picture: Life after the flush
But the real story begins when you push the handle. When the PFAS is introduced into the wastewater treatment, it is frequently included in “biosolids” (treated sewage sludge). It is frequently used as fertilizer for industrial farms.
This is the cycle: the chemicals go from the paper to the water, to the soil, and even into the food we might one day be eating. It is the environmental impact in slow motion, showing the effect our daily choices can have on our footprint.
