If you want to try a saltwater cleanse, talk to your doctor first to determine if it’s a safe option for you. There aren’t any official medical guidelines about who is a candidate for a saltwater flush. Supporters recommend the procedure for people who are chronically constipated or who are experiencing irregular bowel movements.

Greenpeace is investigating seven of the most remote areas around the world for the presence of PFCs, sampling water and snow and testing them to expose how widespread the problem of contamination really is. The DuPont factory, which is one its largest production plants in Europe, opened in 1960. PFCs were not elevated in local drinking water supplies, but following the release of air monitoring results, blood samples were taken from two residents which both showed elevated levels of PFOA.
