Untargeted analysis of environmental contaminants in surface snow samples of Svalbard Islands by liquid chromatography-high resolution mass spectrometry
In recent years, there is increasing attention on the contaminants of emerging concern (CECs), which include plasti-cizers, flame retardants, industrial chemicals, pharmaceuticals, and personal care products, since they have been de-tected even far away from pollution sources. The polar regions are...

In recent years, there is increasing attention on the contaminants of emerging concern (CECs), which include plasti-cizers, flame retardants, industrial chemicals, pharmaceuticals, and personal care products, since they have been de-tected even far away from pollution sources.
