The mercury test of catalysts that has been used and considered universal for 100 years turns out to be ambiguous. This conclusion was reached by a group of scientists including a RUDN chemist. The group confirmed that the ...
In the Canadian Arctic, a mystery has troubled scientists and local communities for decades: Why do marine animals in the western Arctic have higher mercury levels than those in the east?
Many people view the Tibetan Plateau, or "Roof of the World," as a pristine alpine environment, largely untouched by pollution. But researchers, reporting in ACS' journal Environmental Science & Technology, have now shown ...
Mercury is a complex, multifaceted contaminant which can take many different forms. It is poisonous to humans and wildlife and damaging to the environment. Currently, around two thirds of the mercury entering the environment ...
From 1932 to 1968, hundreds of tonnes of mercury seeped into the clear waters of Minamata Bay, Japan, causing health and environmental problems still felt today. As the first global treaty on mercury finally comes into force, ...
The mercury found at very low concentrations in water is concentrated along the entire food chain, from algae via zooplankton to small fish and on to the largest fish—the ones we eat. Mercury causes severe and irreversible ...
According to textbook knowledge, the usual oxidation states of gold in compounds are +I and +III. The divalent form (+II), on the other hand, prefers to form polynuclear compounds or simply undergoes transformation into the ...
In a win-win for a cleaner planet, scientists have devised a way to use waste cooking oil and sulphur to extract the neurotoxin mercury from the environment.
Researchers from the University of Burgos (Spain) have developed a fluorescent polymer that lights up in contact with mercury that may be present in fish. High levels of the metal were detected in samples of swordfish and ...
The biological formation of neurotoxic methyl mercury is an enigmatic process underpinning mercury-related health and environmental hazards. Nevertheless, the exact mechanisms and the factors controlling the process are still ...
