Precipitation influences on uptake of a global pollutant by a coastal avian species

by John Wiley & Sons, Ltd.  (Sep. 19, 2014)

Climatic variation, including precipitation amounts and timing, have been linked to abundance and breeding success of many avian species. Less studied but also of significance is the consequence of climatic variability on the exposure and uptake of nutrients and contaminants by wildlife. We examined mercury (Hg) concentrations in nestling wood ...

Accumulation of mercury and cadmium in rice from paddy soil near a mercury mine

by John Wiley & Sons, Ltd.  (Aug. 2, 2014)

Paddy soil and rice (Oryza sativa L.) in the Wanshan mining area in Guizhou province have been contaminated by toxic trace metals such as cadmium (Cd) and mercury (Hg). This study examined correlations between the types and physico‐chemical parameters of the soil and the contents of trace metals and the different forms of Hg in rice. The study ...

Reducing Mercury Impacts in Small-Scale Gold Mining

by United Nations Environment Programme (UNEP)  (Jul. 25, 2014)

Despite knowing full well the dangers of mercury, millions of small-scale gold miners across the globe continue to use the metal to separate gold from ore - usually because they have little other choice. The mercury is mixed into ore and combines with the gold in a compound that can easily be scooped out and squeezed into a small bar of amalgam. ...

Mercury bioaccumulation in dragonflies (Odonata: Anisoptera): Examination of life stages and body regions

by John Wiley & Sons, Ltd.  (May 31, 2014)

Dragonflies (Odonata: Anisoptera) are an important component of both aquatic and terrestrial food webs and are vectors for methylmercury (MeHg) biomagnification. Variations in mercury content with life stage and body regions may affect the relative transfer of mercury to aquatic or terrestrial food webs; however, there has been little research ...

Case studies - health benefits

by LEDenergysave  (May 6, 2014)

When it comes to LED lighting, most people will tout the low-power draw as a benefit to the environment and the pocketbook. If those aren't good enough reasons to switch, then consider the health benefits. Let's start with what is not in LED light bulbs - toxic materials. Traditional and fluorescent light bulbs both contain mercury. Exposure to ...

Response of fish tissue mercury in a freshwater lake to local, regional, and global changes in mercury emissions

by John Wiley & Sons, Ltd.  (Mar. 21, 2014)

A suite of mechanistic atmospheric and mercury cycling/bioaccumulation models is applied to simulate atmospheric mercury deposition and mercury concentrations in the water column and fish in a mercury‐impaired freshwater lake located in the northeastern United States that receives its mercury loading primarily through deposition. Two ...

Chemical Air Pollution in the Clinical Research Environment

by Commercial Air Filtration  (Feb. 5, 2014)

There has been a revolution in awareness of chemical air pollution in research laboratories. I could tell you several 'horror stories' of casual exposure to mercury vapour, benzene and chromic acid (the ultimate glassware cleaning agent) among innocent biomedical PhD students (including myself) in the 1970s. But researchers in hospitals, and other ...
