1H a - Perfluorinated Substances (WE6/3) Analytical challenges in determination of Telomer 8-2 Alcohol and Telomer-derived fluorosurfactants and polymers in biological and environmental matrices. Szostek, Bogdan1, Prickett, Keith1, Kennedy, S.1, Kaiser, Mary2, 1 DuPont Haskell Laboratory for Health and Environmental Sciences, Newark, DE, USA2 DuPont Central Research and Development, Wilmington, DE, USA ABSTRACT- Telomer B alcohols, including the Telomer 8-2 alcohol, are utilized as intermediates in the manufacture of telomer-based surfactants and polymers that are further incorporated into a variety of products. The Telomer 8-2 alcohol was chosen as a model compound to investigate the environmental behavior of the Telomer alcohol intermediates and as a potential environmental degradation product or biological metabolite of telomer-based surfactants and polymers. The physico-chemical properties of Telomer 8-2 alcohol such as low water solubility, volatility, and the tendency to adsorb on different surfaces, making the analysis of environmental or biological samples very challenging. These properties of the analyte mandate careful consideration of sampling, sample storage, sample processing, and analysis procedures in order to obtain valid data. This presentation will focus on describing analytical methodology utilized to support environmental and biological studies of Telomer 8-2 alcohol. The analytical procedures used for the analysis of Telomer 8-2 alcohol in water, soil, plasma, and animal tissue matrices will be discussed. This presentation will also address the challenges that arise in the analysis of telomer-based surfactants and polymers that are subjected to environmental testing. Analytical instrumentation as well as the analytical methodology suitable for that task will be presented. Key words: analytical procedures, perfluorinated chemicals, telomers |
