Possible uses
This substance has persistent, bioackumulative and toxic properties.This substance is structurally similar to the chemical PFOS, which is a recognised POP under the Stockholm convention. PFDS has been found in human plasma, in birds and fish. It is highly persistent and has the potential for long-range transport. It is expected to be at least as toxic and bioackumulative as PFOS.
Technical function of substances
There is not much known about the use of PFDS or its precursors, although it is thought to be an ingredient in PFOS-based firefighting foams. Source: Gewurtz et al. 2012
