Mercury 'speciation analysis' by using thermal desorption analysis
( 17.04.2017 )
Thermal desorption analysis for mercury is a method to obtain information about different mercury fractions in solid samples by separating them based on their desorption temperature. ...

New Triple Quadrupole ICP-MS launched by Thermo Fisher
( 14.03.2017 )
Thermo Fisher has added a new Triple Quadrupole instrument to its portfolio of ICP-MS systems. The new iCAP TQ ICP-MS allows users to switch between single and triple quadrupole modes in a single mult...

European Medicines Agency recomments to pull linear Gadolinium-based MRI contrast agents from market
( 11.03.2017 )
The Pharmacovigilance and Risk Assessment Committee (PRAC) of the European Medicines Agency (EMA) has recommended the suspension of the marketing authorisations for four linear gadolinium contrast age...

Toxicity of organomercury compounds
( 15.02.2017 )
According to a new CDC study different organomercury compounds share the same fundamental mechanisms related to their toxicity. There is no harmless mercury, both methylmercury and ethylmercury are ex...

Toxic Mercury in Aquatic Life Could Spike due to Climate Change
( 29.01.2017 )
Methylmercury, a highly toxic form of mercury could jump by 300 to 600 percent in zooplankton – tiny animals at the base of the marine food chain – if land runoff increases by 15 to 30 percent, accord...

Use of certified reference materials (CRMs) for speciation analysis
( 16.01.2017 )
The quality of data generated by speciation analysis is especially critical whenever decisions based upon the amounts of species are related to human health risks. The quality and validation of these ...

ERM-AE671: A new Certified Reference Material to make methylmercury measurements in food more reliable
( 05.01.2017 )
Scientists from the European Joint Research Centre (JRC) developed a new certified reference material (CRM) to improve the accuracy of methylmercury measurements in food. This CRM (ERM-AE671) consists...

Solid-phase extraction in speciation analysis
( 14.12.2016 )
Solid phase extraction (SPE) is the most common and widespread separation method used for analyte enrichment, matrix removal and medium exchange....

Liquid-liquid extraction in speciation analysis
( 14.12.2016 )
Since most of the elemental detection methods are based on atomic spectrometry or elemental mass spectrometry, they do not provide any species related information. Using these techniques for speciatio...

Enhanced level of toxic methylmercury in the aquatic environment caused by hydroelectric dams
( 15.11.2016 )
U.S. researchers have now for the first time modeled exposure to methylmercury for humans making use of local food sources impacted by hydroelectric dams. ...
