A novel tool to selectively deliver a control agent to filter-feeding silver and bighead carp
Invasive carp pose substantial economic and ecological damage when populations are widespread in freshwater systems within the United States. Resource managers in the United States have few chemical control tools to selectively remove nuisance fish. This study examined whether Antimycin–A (antimycin) wax encapsulated microparticles could cause selective lethality in invasive carps. The antimycin m
Chronic effects of metal releases from historical mining on threatened crayfish in Madison County Missouri, USA
The Little St. Francis River and its tributaries drain metals-contaminated areas of the Madison County Mines National Priority List Superfund site (MCM) which was designated in 2003 to facilitate remediation of metals contamination within the MCM. One concern for natural resource trustees in the MCM is the potential effects of elevated metals concentrations on the federally threatened St. Francis
Perfluorohexanesulfonic acid (PFHxS) impairs lipid homeostasis in zebrafish larvae through activation of PPARα
Perfluorohexanesulfonic acid (PFHxS), an emerging short-chain per- and polyfluoroalkyl substance, has been frequently detected in aquatic environments. Adverse outcome pathway studies have shown that perfluorinated compounds impair lipid homeostasis through peroxisome proliferator activated receptors (PPARs). However, many of these studies were performed at high concentrations and may thus be a re

From Tread to Watershed: How Tire Wear Particle Chemicals 6PPD and 6PPD-quinone Are Impacting Waterways
Tire and road wear particles (TRWPs) are generated during normal driving conditions and contain both rubber and roadway materials. These particles travel from the roadways and urban environments into surrounding ecosystems where there are deleterious impacts from both the TRWPs and leached rubber chemicals. Recent studies have demonstrated the widespread occurrence and toxicity of TRWPs and their...
Study Finds PFOSA Can Suppress Immune Function in Developing Zebrafish (Danio rerio)
The Stockholm Convention has labeled PFOS a “persistent organic pollutant” due to its long-enduring prevalence, negative toxicological effects, and ability to bioaccumulate in living things. Concerns about PFOSA have been raised due to its similarity to PFOS, its ability to metabolize into PFOS, and its persistent use today
Agricultural Pesticides Could Be Impacting the Natural Beauty at Sequoia National Park Through Atmospheric Deposition
High up in the remote alpine and subalpine lakes of Sequoia and Kings Canyon National Park (SEKI), the crystal-clear lakes appear to be greening with an overpopulation of periphyton. Periphyton is a mixture of various water microbes such as algae, cyanobacteria, and others. Scientists at the USGS Columbia Environmental Research Center and the University of Missouri are working with National Park...
