The presence of per- and polyfluoroalkyl substances (PFAS), organic contaminants first synthesized in the 1940s, has been reported worldwide in a variety of environmental matrices and ultimately in biological systems including humans. Ongoing research into PFAS has included identifying novel PFAS, assessing their fate and transport in the environment, and...
Per- and polyfluoroalkyl substances (PFAS) are a group of anthropogenic compounds that are used ubiquitously in different industrial fields. However, concerns regarding the potential health impacts of PFAS, including perfluoroalkyl carboxylic acids
(PFCAs) and perfluoroalkyl sulfonates (PFSAs), has raised stakeholder interest regarding continued use of PFAS. Analytical methods for PFAS...
The goals of this study were to discover and compare the religious
and philosophical traditions which have shaped Japanese and American
cultures, and to make a case for interdisciplinary transcultural programs
of study in higher education. Specifically, the purposes of this
study were to: (1) describe and trace historically the...
This study's purpose was to provide data on major
inhibitory factors experienced by a third of Oregon high
school English teachers in areas of: attitudes, behaviors,
and physical and emotional effects of theme assessment.
Methods employed two analyses: (1) statistical testing
of the independent variable of teaching experience (1 to...
Per- and polyfluoroalkyl substances (PFAS) are an emerging chemical class of concern. Recently in the United States, Health Advisory Limits for two PFAS in drinking water were established for perfluorooctane sulfonate and perfluorooctanoate in drinking water (set to 70 ng/L combine concentration) by the EPA. Because of PFAS mobility, persistence,...
