Air quality in Europe - 2014 report

by European Environment Agency (EEA)  (Nov. 19, 2014)

Despite considerable improvements in the past decades, Europe is still far from achieving levels of air quality that do not pose unacceptable risks to humans and the environment. Air pollution is the top environmental risk factor of premature death in Europe; it increases the incidence of a wide range of diseases and has several environmental ...

Air Rule for Cement Kilns Requires 92 Percent Cut in Mercury Emissions

by Ohio Lumex Co., Inc.  (Nov. 1, 2014)

Portland cement kilns will be required to reduce emissions of mercury by 92 percent as part of an Environmental Protection Agency final rule announced Aug. 9 that imposes controls for several toxic pollutants. Although most of the emissions standards in the final rule are less stringent than what the agency had proposed in 2009, the cement ...

Effective Co2 Removal

by SnowPure Water Technologies  (Jan. 1, 2011)

CO2 is difficult for both RO and EDI to remove since it has no charge, or is weakly ionized. It is important to remove CO2 in the EDI pretreatment because it will lower the EDI product water quality, will compete with silica for removal, and may lead to scaling of the EDI. Here are 3 ways to remove CO2 effectively in a system: Corosex II ...

Cross‐basin comparison of mercury bioaccumulation in lake Huron lake trout emphasizes ecological characteristics

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

Understanding factors influencing mercury (Hg) bioaccumulation in fish is important for examining both ecosystem and human health. However, little is known of how differing ecosystem and biological characteristics can drive Hg bioaccumulation in top predators. This study compared and contrasted Hg bioaccumulation in multiple age classes of ...

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 ...
