Widespread Occurrence of the Highly Toxic Dimethylated Monothioarsenate in Rice
( 12.05.2022 )
An international group of researchers have found that the highly toxic dimethylated monothioarsenate is present in rice from all continents at concentrations of concern....

Interaction of gadolinium-based contrast agents with humic substances
( 26.04.2022 )
Researchers from the University of Münster have studied the interaction of gadolinium-based contrast agents (GBCAs) with humic acids as potential binding partners in the aquatic environment. Speciatio...

Simple and Fast On-line Speciation of Inorganic Antimony Coupled to ICP-MS
( 12.04.2022 )
A group of researchers from Spain and Brazil have developed a two-step procedure for the speciation of inorganic antimony. The procedure is fully automated by using a multisyringe flow injection manif...

( 08.04.2022 )
A group of Chinese researchers has presented a method for the selenium speciation analysis in fortified vegetables providing high extraction yields and good detection power....

Combined speciation analysis and elemental bioimaging provides new information about the retention of gadolinium in kidney following the application of some MRI contrast agents
( 28.02.2022 )
A group of researchers from Germany and France have combined methods of speciation analysis and elemental bioimaging to obtain information about the gadolinium species retained in kidneys of rats foll...

Quantification of vanadium species in vanadium-fortified apples by liquid chromatography hyphenated with inductively coupled plasma atomic emission spectrometry
( 14.02.2022 )
A group of researchers from South Korea have developed a method for the determination of vanadium species in fruit products. ...

An easy way to selectively determine organomercury in seafood
( 11.02.2022 )
A group of researchers from Italy have proposed a very simple, highly selective method for the speciation analysis of methylmercury in seafood. ...

Thiolation of trimethylantimony: A new cornerstone of the biogeochemistry of antimony
( 17.01.2022 )
Chinese researchers have identified a previously unknown Sb species, trimethylmonothioantimony (TMMTSb). TMMTSb was readily formed when trimethylantimony (TMSb) reacted with sulfide....

Reducing mercury pollution entering lakes quickly lowers how much harmful mercury is found in fish
( 10.01.2022 )
This is the outcome of a study published a few weeks ago in Nature. During the study, conducted over 15 years, scientists intentionally added a traceable form of mercury to a lake and its watershed. ...

Selenium species are partly converted during their enzymatic extraction from biological samples with protease XIV
( 14.12.2021 )
Researchers from Prague, Czech Republic have investigated the stability of selenium species during extraction from biological material. By using the most common agent Protease XIV for extraction from ...
