How mercury gets into the sea

Chemical fingerprint reveals origin

04-Oct-2021

Mercury released into the atmosphere by industry enters the sea and from there makes its way into the food chain. Now, an analysis by the University of Basel has revealed how the harmful substance enters seawater in the first place. This is not primarily via rainfall, as previously assumed, but ...

Disproving the universal nature of the mercury test

Mercury test of catalysts that has been considered universal for 100 years seems to be ambiguous

26-Oct-2018

The mercury test of catalysts that has been used and considered universal for 100 years, turned out to be ambiguous. This conclusion was made by a group of scientists including a RUDN chemist. The group confirmed that the test required additional control experiments to verify its results. The ...

Diatom ooze sediments are a large marine mercury sink

Sediments reveal mercury pollution in Antarctica since the beginning of the industrial period

30-Jul-2018

Mercury has been used and released by humans by multiple processes such as gold and silver mining and emissions of mercury to the atmosphere by coal burning, to name the most important ones. These processes have caused strong enrichment of mercury in the environment especially in aquatic systems. ...

Don't Give the Slightest Chance to Toxic Elements in Medicinal Products

New high-accuracy reference solutions for the SI-traceable measurement

27-Mar-2018

Lead, cadmium, mercury, and arsenic do not belong in medicinal products. International requirements for the quality of medicines have therefore become more stringent and introduced new control requirements. Hence, it makes sense to use high-accuracy reference solutions with defined contents of ...

Detecting Mercury with Gold

Individual gold nanorods could be used to develop smaller, portable mercury sensors

09-Mar-2017

Mercury is harmful even in small amounts. Detecting it currently requires expensive equipment. Researchers are working on a faster and cheaper alternative: a portable sensor that can perform a rapid analysis in the field. The key is finding something small and accurate enough to do the job.For ...
