Perfluorohexanesulfonic acid (PFHxS) induces hepatotoxicity through the PPAR signaling pathway in larval zebrafish (Danio rerio)
In recent years, the industrial substitution of long-chain per- and polyfluoroalkyl substances (PFAS) with short-chain alternatives has become increasingly prevalent, resulting in the widespread environmental detection of perfluorohexanesulfonic acid (PFHxS), a short-chain PFAS. However, there remains limited information about the potential adverse effects of PFHxS at environmental concentrations
Evolutionary perspectives on thiamine supplementation of managed Pacific salmonid populations
Thiamine deficiency complex (TDC) has been identified in an ever-expanding list of species and populations. In many documented occurrences of TDC in fishes, juvenile mortality can be high—up to 90% at the population level. Such sweeping demographic losses and concomitant decreases in genetic diversity due to TDC can be prevented by treating pre-spawn females or fertilized eggs with supplemental th
Establishment of a cell culture from Daphnia magna as an in vitro model for (eco)toxicology assays: Case study using Bisphenol A as a representative cytotoxic and endocrine disrupting chemical
Bisphenol A (BPA) is a widely used industrial compound found in polycarbonate plastics, epoxy resin, and various polymer materials, leading to its ubiquitous presence in the environment. The toxicity of BPA to aquatic organisms has been well documented following in vivo exposure scenarios, with known cytotoxic and endocrine-disrupting effects. As such, BPA was used in this study as a well-characte

Per- and Polyfluoroalkyl Substance (PFAS) Core Technology Team
The Per- and Polyfluoroalkyl Substance (PFAS) Core Technology Team (CTT) within the Environmental Health Program partners with external and internal stakeholders to develop and apply analytical methods for measuring PFAS in complex matrices, addressing environmental health issues related to transport, distribution, fate, effects, and exposure.
Development of a Ploidy Distinction Application: A Machine Learning Approach for Discriminating Triploid and Diploid Grass Carp (Ctenopharyngodon idella) in the Field
USGS scientists are researching a machine learning approach that can enable fisheries personnel in the field to determine the ploidy of wild-caught invasive carp.
Gut-Liver Axis: Review on How Microplastics Can Cause Toxicity Through an Interaction Between the Gut, Microbial Community, and Liver
Microplastics can cause liver damage when consumed by terrestrial and aquatic organisms. This review proposes a novel mechanism to help explain the toxic effects following ingestion, which involves the gut, microbial community, and liver through the gut-liver axis.
