Spectral characteristics of CDOM in water column are a key parameter for bio-optical modeling. Knowledge of CDOM optical properties and spatial discrepancy based on the relationship between water quality and spectral parameters in Yinma River watershed with in situ data collected highly-polluted waters are exhibited in this study. Seasonal field data sets collected over a period of 2 months in ...

The southeast of the Betic Cordilleras has long been recognized as an area with numerous geothermal anomalies of regional character. Many thermal springs appear related to currently tectonically active fault systems. Carbon dioxide and other gases in these waters have been mobilized through those fault systems. The great depth of these "slip-strike zones" affects the entire thickness of the lit...

The concentrations of Cu, Pb, and Zn in the crystalline style (CS) and in the remaining soft tissues (ST) of the green-lipped mussel Perna viridis from 10 geographical sites along the coastal waters off peninsular Malaysia were determined. The CS, compared with the remaining ST, accumulated higher levels of Cu in both contaminated and uncontaminated samples, indicating that the style has a high...

PCBs are a group of synthetic organochlorine chemicals widely used as dielectric and coolant fluids in transformers and capacitors. In 1977, the U.S. banned the production of PCBs out of concern for their persistence in the environment as well as evidence indicating that PCBs were bioaccumulative and has the potential to cause toxic impacts. Though PCBs are no longer produced, there are continu...

Using top predators as sentinels of the marine environment, Hg contamination was investigated within the large subantarctic seabird community of Kerguelen Islands, a remote area from the poorly known Southern Indian Ocean. Chicks of 21 sympatric seabirds presented a wide range of Hg concentrations, with the highest contaminated species containing ~102 times more feather Hg than the less contami...

Lightly salted surface waters Hydraulic fracturing uses a water-based mixture to open up tight oil and gas formations. The process is mostly contained, but concerns remain about the potential for water contamination. Bonetti et al . found small increase in certain ions associated with hydraulic across several locations United States (see Perspective by Hill Ma). These increases appeared 90 180 ...

At the University Hospital of Besançon (département of Doubs, France), an unusually high number of patients were hospitalized for hepatitis A during the 1999-2000 period, some of whom had not travelled abroad. This prompted us to conduct an investigation on a population basis and search for clusters of cases possibly related to local sources of contamination. Accordingly, case definition was re...

Beginning with detection of elevated levels of mercury in largemouth bass in 1989 (FSU 1990; Ware et al. 1990), it has become increasingly apparent that the South Florida Ecosystem is extensively contaminated. In response to continuing accretion of reports of significant Hg contamination, the State of Florida has issued human health advisories that ban or restrict consumption of freshwater fish...
