Impact/Purpose:
The general goals of this research are to meet OPPT's need for data and information regarding the stability of TBPPs in soils. We plan to address these needs with a series of lab experiments in which FBPs are exposed to selected natural and amended soils. We anticipate that, as we learn about the general behavior of FBPs in soils, we will develop a protocol for testing FBPs in soils that has procedures similar to the guidelines described in OECD 307.
Description:
Fluorotelomer-based polymers (FBPs) are used in a wide variety of consumer products and are widely distributed throughout society. Accordingly, there is great interest in whether and how fast these materials might degrade in various environmental settings. A useful quality of FBPs is the chemical stability of the polymers and, therefore, half-lives are anticipated to be long relative to typical laboratory experiments.
