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:
Chemical data for perfluorinated octanoic acid (PFOA) and soil partitioning that are available in the literature and from third-parties were used to calculate the propensity for PFOA to sorb to soils. Based upon calculations described here-in, as well as monitoring data from near industrial facilities, PFOA does appear to partition to soil significantly.
