On a facebook compost group: 

These chemicals are, on a human life timeframe, permanent in our environment. They will eventually break down, but at the rate we're going, we may not, as a species, be around to see that happen. There are over 4700 chemicals in this group... All man-made.

One of their properties is making paper very water resistant, which is why leaf collection bags don't break apart when they get wet and heavy. In our area plastic bags are illegal for leaf/garden waste. People must use the paper bags or the leaves are not picked up. Last year I gathered 125 bags of leaves from my community. The leaves are Garden Gold, but the bags are toxic, although my research days the level of PFAS chemicals is within safe limits. When a chemical is permanent, it will bioaccumulate, so I don't see how any level can be considered safe. So what to do with all those bags going forward???? Burn them in my wood stove (AI query says wood stove may not attain temperatures hot enough for long enough to completely break them down)??? Compost them??? Send them to the landfill???

My first introduction to these chemicals was through an article about PFAS getting into farmers' field and then into the ground water system in New England area of USA. The farms and water are now so toxic that it's illegal to grow/sell food on those farms and the water is unsafe to drink... so the farmers have lost their life work!!! The chemicals came into their system through municipal sewage treated with PFAS and then spread on their land. This is about as frightening a scenario as one could imagine... the stuff of sci-fi horror movies .. except it's not a movie!!!
