Identification of lead contamination sources in soil reference materials using the continuous on-line leaching method and inductively coupled plasma mass spectrometry
( 14.11.2021 )
Researchers from Canada have developed a method for continuous leaching of soil samples providing improved data for the bioaccessible lead. The obtained elution profile shows different fractions indic...

Fast and Automated Monitoring of Gadolinium-based Contrast Agents in Surface Waters
( 13.11.2021 )
A team of researchers from Germany and the US have developed a method based on ion-chromatography for the sensitive and selective determination of gadolinium-based contrast agents in surface waters. T...

EVISA News revisited: Potential link between aluminum salts in deodorants and breast cancer warrants further research
( 14.10.2021 )
15 years ago we reported about the hypothesis that aluminum salts in antiperspirants are causing breast cancer. It is time to follow up and to summarize what has been investigate so far....

How mercury gets into the sea
( 10.10.2021 )
Mercury released into the atmosphere by mainly thermic industrial processes is transported via different ways to the sea where it enters the marine food web. Now a study directed by the University of ...

New Strategy for Speciation Analysis of Gadolinium retained in Bone after Application of MR Contrast Agents
( 16.09.2021 )
Researchers from Germany and France have developed a strategy to obtain information about gadolinium species that degrade during extraction from bone tissue. ...

On-column internal standardisation as an alternative calibration strategy for speciation analysis
( 27.08.2021 )
Researchers from LGC Ltd. (UK) developed a calibration method for speciation analysis using chromatographic separation that can correct for on-column analyte losses and signal drift and can be applied...

Arsenic Species in Seaweeds Commercially Available in the United States
( 16.08.2021 )
Researchers from U.S. FDA have analysed 46 seaweed samples purchased from the U.S. market for total arsenic and arsenic speciation. Arsenosugars were dominant in most seaweeds, inorganic arsenic did n...

Iron species determination by high performance liquid chromatography coupled with plasma source atomic emission spectrometry
( 14.08.2021 )
