Effects of Ibuprofen on hematological, biochemical and enzymological parameters of blood in an Indian major carp, Cirrhinus mrigala

In the present investigation, the most commonly used pharmaceutical drug Ibuprofen (IB) was exposed to an Indian major carp Cirrhinus mrigala under static bioassay method to estimate its toxicological effects for a period of 35 days. The median lethal concentration (LC 50) of IB to the fish C. mrigala for 24 h was found to [...]

Red Sea to Dead Sea Water Channeling Project Receives Final Approval

A World Bank sponsored project to restore water levels in the Dead Sea while also providing desalinated water and hydropower to the region received a final environmental approval and construction is slated to begin in June. Final Report (pdf)

Leviathan™ Technology from Floating Island International

Floating Island International offers a variety of products incorporating patented BioHaven® technology, none more powerful than the Leviathan.Leviathan uses integrates high-volume, low-head circulation with matrix surface area for maximum wetland performance. Its efficient air-driven directional diffuser draws in and aerates in excess of ten thousand gallons of water per minute, pushing it through the BioHaven [...]

Long-term recovery of lakes in the Adirondack region of New York to decreases in acidic deposition

The percentage of acidic Adirondack lakes (ANC <0 μeq L−1) decreased from 15.5% (284 lakes) to 8.3% (152 lakes) since the implementation of the Acid Rain Program and the Nitrogen Budget Program. Two measures of ANC were considered in our analysis: ANC determined directly by Gran plot analysis (ANCG) and ANC calculated by major ion [...]

The environmental costs of mountaintop mining valley fill operations for aquatic ecosystems of the Central Appalachians

Southern Appalachian forests are recognized as a biodiversity hot spot of global significance, particularly for endemic aquatic salamanders and mussels. The dominant driver of land-cover and land-use change in this region is surface mining, with an ever-increasing proportion occurring as mountaintop mining with valley fill operations (MTVF). In MTVF, seams of coal are exposed using [...]

An Automated Platform for Phytoplankton Ecology and Aquatic Ecosystem Monitoring

High quality monitoring data are vital for tracking and understanding the causes of ecosystem change. We present a potentially powerful approach for phytoplankton and aquatic ecosystem monitoring, based on integration of scanning flow-cytometry for the characterization and counting of algal cells with multiparametric vertical water profiling. This approach affords high-frequency data on phytoplankton abundance, functional [...]

Long-Term Temporal Variability in Hydrogen Peroxide Concentrations in Wilmington, North Carolina USA Rainwater

Measurements of hydrogen peroxide (H2O2), pH, dissolved organic carbon (DOC), and inorganic anions (chloride, nitrate, and sulfate) in rainwater were conducted on an event basis at a single site in Wilmington, NC for the past decade in a study that included over 600 individual rain events. Annual volume weighted average (VWA) H2O2 concentrations were negatively [...]
