- 339 - New Model Estimates PFAS Exposures From Contaminated Drinking Water -- Chiu
Release Date: 03/01/2023
Researchers partially funded by the NIEHS Superfund Research Program (SRP) developed a model to estimate individual exposure to four per- and polyfluoroalkyl substances (PFAS) commonly found in drinking water. The model integrates published data from multiple studies on PFAS levels in human blood along with measured PFAS concentrations in drinking water. Tools for estimating PFAS exposure from contaminated drinking water can inform public health risk assessments and advisories.
- 338 - Combining Analytical Chemistry and Machine Learning to Detangle Mixtures -- Halas
Release Date: 02/01/2023
NIEHS Superfund Research Program (SRP)-funded researchers demonstrated a significant step toward identifying individual chemical components in complex mixtures. Their approach uses advanced analytical techniques and sophisticated machine learning approaches while overcoming the time-consuming separation steps that preceded traditional chemical analysis.
- 337 - Dioxin Disrupts Liver Cells in Mice, Potential Link with Liver Disease -- Zacharewski, Nault
Release Date: 01/11/2023
An NIEHS Superfund Research Program (SRP)-funded study in mice reported that exposure to a type of dioxin can alter cells in the liver, their metabolic characteristics, and how they are organized within the liver. According to the researchers, these changes in cell behavior and organization play a role in the development of dioxin-induced liver diseases, such as fibrosis and fatty liver disease.
