Presented at Society of Environmental Toxicology and Chemistry Annual Meeting, Baltimore, MD, November 13 - 17, 2005.
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:
Soils that receive land application of treated wastewater from carpet manufacturing plants were sampled for perfluorooctanoic acid (PFOA) and other perfluorinated chemicals (PFCs) that are potential degradation products of fluorotelomer-based polymers (FBPs). Soils from other potentially impacted sites and soils remote from exposure to PFCs (except by atmospheric deposition) were analyzed to determine ambient levels of PFCs as well.
