Determination of gadolinium-based MRI contrast agents in fresh and oceanic waters of Australia
( 14.02.2021 )
Researchers from the University of Technology Sydney and from University of Münster have developed a method employing micro-solid phase extraction followed by HILIC-ICP-MS for the determination of the...

Effect of cooking on the speciation of chromium in food
( 08.02.2021 )
A group of researchers from France and Denmark have investigated the effect of several cooking procedures on the speciation of chromium in food. The results of their study clearly showed that no oxida...

Detoxification of Methylmercury in Higher Organisms
( 04.02.2021 )
An international team of researchers have studied the in vivo detoxification of methylmercury in multiple animals from two phyla (a waterbird, freshwater fish, and earthworms). They report that the me...

A universal method for the speciation analysis of arsenic in various seafoods
( 19.01.2021 )
A Chinese group of researchers have developed an analytical method for arsenic species that can be used for various seafoods such as seaweed, fish, shellfish and shrimp. Using microwave-assisted extra...

Mercury-binding proteins in tuna and salmon
( 18.01.2021 )
A Chinese group of researchers investigated the mercury-binding proteins in tuna and salmon. More than half of the mercury from fish muscle was found in the soluble protein fraction. Beta-actin was id...

New isotope ratio mass spectrometry system delivers high-precision analysis for a range of applications
( 07.01.2021 )
A new inductively coupled plasma mass spectrometry (ICP-MS) instrument has been designed to enable scientists working in earth sciences, nuclear safeguards, and biomedical research to conduct reliable...

Speciation analysis of Gadolinium-based contrast agents using hydrophilic interaction liquid chromatography hyphenated with inductively coupled plasma-mass spectrometry by avoiding organic solvents
( 02.12.2020 )
A group of Japanese researchers have developed a HILIC separation of Gadolinium-based contrast agents using an aqueous mobile phase. ...

Man made mercury pollution is reaching even deep ocean organisms
( 23.11.2020 )
The sinking carcasses of fish from near-surface waters deliver toxic mercury pollution to the most remote and inaccessible parts of the world’s oceans, including the deepest spot of them all: the 36,0...

Transformation of arsenic species during ultrasonic sample pretreatment
( 17.11.2020 )
A group of Chinese researchers now studied the transformation kinetics of different arsenic species in aqueous solution by ultrasonic treatment in order to select optimum conditions for efficient extr...

New way of cooking rice removes arsenic and retains mineral nutrients, study shows
( 10.11.2020 )
Cooking rice in a certain way removes over 50 per cent of the naturally occurring arsenic in brown rice, and 74 per cent in white rice, according to new research....
