Critical review of mercury SQVs for the protection of benthic invertebrates

by John Wiley & Sons, Ltd.  (Oct. 15, 2014)

Sediment Quality Values (SQVs) are commonly used – and misused – to characterize the need for investigation, understand causes of observed effects, and derive management strategies to protect benthic invertebrates from direct toxic effects. We compiled > 40 SQVs for mercury, nearly all of which are “co‐occurrence” SQVs derived from databases of ...

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) ...

Seasonal and year‐to‐year variation of mercury concentration in perch (Perca fluviatilis) in Boreal lakes

by John Wiley & Sons, Ltd.  (Sep. 17, 2014)

The authors examined the seasonal and year‐to‐year variations of mercury (Hg) concentrations in populations of perch (Perca fluviatilis) from 2 boreal freshwater lakes in southeast Norway. Fish Hg concentrations were determined seasonally (spring, summer, and autumn) over 3 yr (2010, 2011, and 2012) to test the hypothesis that there are ...

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 ...

Archaeological survey 2

by ZZ Resistivity Imaging Pty. Ltd.  (Jul. 23, 2014)

The site of the Meadows’ Wesleyan Cemetery in the Adelaide is thought to contain more than 130 unmarked graves. This site initially had a chapel constructed on it in 1840 and the first burial in 1855.  The initial chapel was replaced by a more substantial stone building in 1856.  Burials continued in this cemetery sporadically ...


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 ...

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 ...

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. ...
