Chronic microfiber exposure in adult Japanese medaka (Oryzias latipes).
(PloS one, 2020-01)Microplastic fibers (MFs) pollute aquatic habitats globally via sewage release, stormwater runoff, or atmospheric deposition. Of the synthetic MFs, polyester (PES) and polypropylene (PP) are the most common. Field studies ... -
Crumbling Infrastructure and Learning Impairment: A Call for Responsibility.
(Environmental health perspectives, 2016-05) -
Developmental exposure to a complex PAH mixture causes persistent behavioral effects in naive Fundulus heteroclitus (killifish) but not in a population of PAH-adapted killifish.
(Neurotoxicol Teratol, 2016-01)Acute exposures to some individual polycyclic aromatic hydrocarbons (PAHs) and complex PAH mixtures are known to cause cardiac malformations and edema in the developing fish embryo. However, the heart is not the only organ ... -
Elucidating the impact of microbial community biodiversity on pharmaceutical biotransformation during wastewater treatment.
(Microbial biotechnology, 2018-11)In addition to removing organics and other nutrients, the microorganisms in wastewater treatment plants (WWTPs) biotransform many pharmaceuticals present in wastewater. The objective of this study was to examine the relationship ... -
Environmental Impacts of the Coal Ash Spill in Kingston, Tennessee: An 18-Month Survey
(2010)An 18 month investigation of the environmental impacts of the Tennessee Valley Authority (TVA) coal ash spill in Kingston, Tennessee combined with leaching experiments on the spilled TVA coal ash have revealed that leachable ... -
Functional elastic hydrogel as recyclable membrane for the adsorption and degradation of methylene blue.
(PloS one, 2014-01)Developing the application of high-strength hydrogels has gained much attention in the fields of medical, pharmacy, and pollutant removal due to their versatility and stimulus-responsive properties. In this presentation, ... -
Isotopic imprints of mountaintop mining contaminants.
(Environ Sci Technol, 2013-09-03)Mountaintop mining (MTM) is the primary procedure for surface coal exploration within the central Appalachian region of the eastern United States, and it is known to contaminate streams in local watersheds. In this study, ... -
Legacy of Coal Combustion: Widespread Contamination of Lake Sediments and Implications for Chronic Risks to Aquatic Ecosystems.
(Environmental science & technology, 2022-10)Elevated concentrations of toxic elements in coal ash pose human and ecological health risks upon release to the environment. Despite wide public concerns about water quality and human health risks from catastrophic coal ... -
Legacy source of mercury in an urban stream-wetland ecosystem in central North Carolina, USA.
(Chemosphere, 2015-11)In the United States, aquatic mercury contamination originates from point and non-point sources to watersheds. Here, we studied the contribution of mercury in urban runoff derived from historically contaminated soils and ... -
Long-term transformation and fate of manufactured ag nanoparticles in a simulated large scale freshwater emergent wetland.
(Environ Sci Technol, 2012-07-03)Transformations and long-term fate of engineered nanomaterials must be measured in realistic complex natural systems to accurately assess the risks that they may pose. Here, we determine the long-term behavior of ... -
Parental dietary seleno-L-methionine exposure and resultant offspring developmental toxicity.
(Aquatic toxicology (Amsterdam, Netherlands), 2016-01)Selenium (Se) leaches into water from agricultural soils and from storage sites for coal fly ash. Se toxicity causes population and community level effects in fishes and birds. We used the laboratory aquarium model fish, ... -
Potential impacts of leakage from deep CO2 geosequestration on overlying freshwater aquifers.
(Environ Sci Technol, 2010-12-01)Carbon Capture and Storage may use deep saline aquifers for CO(2) sequestration, but small CO(2) leakage could pose a risk to overlying fresh groundwater. We performed laboratory incubations of CO(2) infiltration under oxidizing ... -
Radium and barium removal through blending hydraulic fracturing fluids with acid mine drainage.
(Environ Sci Technol, 2014-01-21)Wastewaters generated during hydraulic fracturing of the Marcellus Shale typically contain high concentrations of salts, naturally occurring radioactive material (NORM), and metals, such as barium, that pose environmental ... -
Reduction in urinary arsenic levels in response to arsenic mitigation efforts in Araihazar, Bangladesh.
(Environ Health Perspect, 2007-06)BACKGROUND: There is a need to identify and evaluate an effective mitigation program for arsenic exposure from drinking water in Bangladesh. OBJECTIVE: We evaluated the effectiveness of a multifaceted mitigation program ... -
Silver toxicity across salinity gradients: the role of dissolved silver chloride species (AgCl x ) in Atlantic killifish (Fundulus heteroclitus) and medaka (Oryzias latipes) early life-stage toxicity.
(Ecotoxicology, 2016-08)The influence of salinity on Ag toxicity was investigated in Atlantic killifish (Fundulus heteroclitus) early life-stages. Embryo mortality was significantly reduced as salinity increased and Ag(+) was converted to AgCl(solid). ... -
Survey of the potential environmental and health impacts in the immediate aftermath of the coal ash spill in Kingston, Tennessee.
(Environ Sci Technol, 2009-08-15)An investigation of the potential environmental and health impacts in the immediate aftermath of one of the largest coal ash spills in U.S. history at the Tennessee Valley Authority (TVA) Kingston coal-burning power plant ... -
The Elizabeth River Story: A Case Study in Evolutionary Toxicology.
(J Toxicol Environ Health B Crit Rev, 2015)The Elizabeth River system is an estuary in southeastern Virginia, surrounded by the towns of Chesapeake, Norfolk, Portsmouth, and Virginia Beach. The river has played important roles in U.S. history and has been the location ... -
The strontium isotope fingerprint of phosphate rocks mining.
(The Science of the total environment, 2022-12)High concentrations of metal(loid)s in phosphate rocks and wastewater associated with phosphate mining and fertilizer production operations pose potential contamination risks to water resources. Here, we propose using Sr ... -
