Thank you for making a post about this study and sharing the information with others here. Never was fond of using a pipe and have always preferred a joint instead. I am much more worried about contaminants in our municipal supplied drinking water and vegetables and fruit that we purchase in the market as well as contaminants in grain such as corn, wheat and rice.
There is two small factories in my area and they have been blamed for tainting the aquifer with pfoas as far as 10 miles from the factory, and I find this much more disturbing.
