Algal blooms and the nitrogen-enrichment hypothesis in Florida springs: evidence, alternatives, and adaptive management.
(Ecol Appl, 2010-04)Contradictions between system-specific evidence and broader paradigms to explain ecosystem behavior present a challenge for natural resource management. In Florida (U.S.A.) springs, increasing nitrate (NO3-) concentrations ... -
Assessing the nonlinear association of environmental factors with antibiotic resistance genes (ARGs) in the Yangtze River Mouth, China.
(Scientific reports, 2023-11)The emergence of antibacterial resistance (ABR) is an urgent and complex public health challenge worldwide. Antibiotic resistant genes (ARGs) are considered as a new pollutant by the WHO because of their wide distribution ... -
Boron and strontium isotopic characterization of coal combustion residuals: validation of new environmental tracers.
(Environ Sci Technol, 2014-12-16)In the U.S., coal fired power plants produce over 136 million tons of coal combustion residuals (CCRs) annually. CCRs are enriched in toxic elements, and their leachates can have significant impacts on water quality. Here ... -
Early hematopoietic effects of chronic radiation exposure in humans.
(Health Phys, 2010-09)The major goal of this study is to investigate and quantitatively describe the nature of the relationship between the characteristics of chronic exposure to ionizing radiation and specific patterns of hematopoiesis reduction. ... -
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 ... -
Experimental evaluation of evolution and coevolution as agents of ecosystem change in Trinidadian streams.
(Philos Trans R Soc Lond B Biol Sci, 2009-06-12)Evolution has been shown to be a critical determinant of ecological processes in some systems, but its importance relative to traditional ecological effects is not well known. In addition, almost nothing is known about the ... -
Impacts of shale gas wastewater disposal on water quality in western Pennsylvania.
(Environ Sci Technol, 2013-10-15)The safe disposal of liquid wastes associated with oil and gas production in the United States is a major challenge given their large volumes and typically high levels of contaminants. In Pennsylvania, oil and gas wastewater ... -
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 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 ... -
Oil and gas projects in the Western Amazon: threats to wilderness, biodiversity, and indigenous peoples.
(PLoS One, 2008-08-13)BACKGROUND: The western Amazon is the most biologically rich part of the Amazon basin and is home to a great diversity of indigenous ethnic groups, including some of the world's last uncontacted peoples living in voluntary ... -
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 ... -
Wetlands as an alternative stable state in desert streams.
(Ecology, 2008-05)Historically, desert drainages of the American southwest supported productive riverine wetlands (ciénegas). Region-wide erosion of ciénegas during the late 19th and early 20th century dramatically reduced the abundance of ...
