Methylmercury accumulation and elimination in mink (Neovison vison) hair and blood: Results of a controlled feeding experiment using stable isotope tracers

by John Wiley & Sons, Ltd.  (Sep. 25, 2014)

Concentrations of metals in hair are used often to develop pharmacokinetic models for both animals and humans. While data on uptake are available, elimination kinetics are less well understood; stable isotope tracers provide an excellent tool for measuring uptake and elimination kinetics. In the present study, methylmercury (MeHg) ...

One Billion Devices

by Ensia  (Aug. 13, 2014)

Increasing standards of living mean more — literally hundreds of millions more — computers, cell phones and other electronic devices are being deployed in developing nations. But what happens when these hot new devices are no longer wanted? Researchers from two institutions in India — the PEC University of Technology in ...

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. ...

EFFECT OF CROPPING SYSTEMS ON HEAVY METAL DISTRIBUTION AND MERCURY FRACTIONATION IN THE WANSHAN MINING DISTRICT, CHINA: IMPLICATIONS FOR ENVIRONMENTAL MANAGEMENT

by John Wiley & Sons, Ltd.  (Jun. 12, 2014)

We studied the concentration of heavy metals and mercury fractionation in contaminated soil for two agricultural land use systems (paddy rice and dry‐land) at the Wanshan Hg mine in China. The average concentration of chromium, lead, copper, nickel and zinc was generally lower in paddy‐rice (PR) soil relative to corn field (CF) soil. Soil under ...

Moisture Audits & Analyser Performance Assessments at Woodside, Karratha - Case Study

by Moisture Control & Measurement Ltd  (Jun. 10, 2014)

Woodside had been experiencing intermittent blockages in 4/5 S1406 LNG trains since September 2008 and had been unable to pinpoint the source of the problems. Repeated hydrate formations were leading to reduced productivity and the existing process monitoring instrumentation had failed to confirm moisture breakthrough on the beds. The site's ...

Continuous Mercury Monitoring Benefits Cement Plants

by Gasmet Technologies Oy  (May 13, 2014)

Antti Heikkilä from Gasmet Technologies highlights the challenges faced by mercury monitoring in cement kilns, and explains how a new continuous mercury monitoring system addresses these issues and provides process operators with an opportunity to improve environmental performance and demonstrate compliance with forthcoming legislation. ...

Remediation of mercury contaminated industrial site for future expansion - case study

by econ industries GmbH  (Feb. 4, 2014)

70,000 tons of mercury contaminated soil and building rubble have to be cleaned in an industrial facility in the south of France until 2013. For the realization of this remediation work, an econ industries VacuDry® 12,000 has been in operation since early 2011. After the treatment the mercury free soils can be re-used on-site as building ...

Lifelong exposure to methylmercury disrupts stress‐induced corticosterone response in zebra finches (Taeniopygia guttata)

by John Wiley & Sons, Ltd.  (Jan. 16, 2014)

Mercury can disrupt the endocrine systems of mammals and fish, but little is known about its effects on avian hormones. We employed an experimental manipulation to show that methylmercury suppresses the stress‐induced corticosterone response in birds, an effect previously unreported in the literature. Corticosterone regulates many normal ...

Human mercury exposure and effects in Europe

by John Wiley & Sons, Ltd.  (Dec. 4, 2013)

The effects of human exposure to mercury (Hg) and its compounds in Europe have been the focus of numerous studies that differed in their design, including recruiting different population groups at different levels of exposure and by using different protocols and recruitment strategies. The objective of this work was to review current studies of ...
