TL;DR: In this paper, solid phase microextraction combined with electrochemistry (SPME/EC) for trace level mercury determination was reported, and an SPME/EC fibre was made of a carbon steel wire with a 10 µm gold coating.
Abstract: Solid-phase microextraction combined with electrochemistry (SPME/EC) for trace level mercury determination is reported. An SPME/EC fibre was made of a carbon steel wire with a 10 µm gold coating. Mercury(II) ions were electrochemically extracted from aqueous solution, and desorbed with a dedicated desorption system, then detected by ion-trap GC–MS. Mercury(II) ions in aqueous solution, and mercury vapour in gas, were detected. Inorganic mercury and organomercury compounds were differentiated.

TL;DR: In this paper, a large increase in thermal stability, a marked shift in the 199Hg resonance to lower frequency and an increase in the coupling constant 1 J( 13 C  199 Hg ) for the HgR bond was reported.

TL;DR: In this article, the role of natural organic substances in dissolution, transport and concentrating of mercury in environment are generalized, and the interaction of mercury (II) with fulvic acids (FA) and humic acids (HA) have been studied.
Abstract: The data about the role of natural organic substances in dissolution, transport and concentrating of mercury in environment are generalized. The interaction of mercury (II) with fulvic acids (FA) and humic acids (HA) have been studied. It has been shown that in the reaction of mercury ions with FA stable soluble high-molecular mercury (II) fulvate complexes are formed. These complexes are predominating form of mercury in surface fresh waters. The interaction of mercury (II) with FA leads to the abrupt increase of mercury mobility in waters and sails. On the contrary HA behave as complexing sorbents promoting mercury concentrating in soils and bottom sediments. Another direction of mercury (II) interaction with humus acids is the formation of organomercury compounds. Principal possibility of abiological methylation of mercury by means of interaction of mercury (II) with FA has been proved. The output of methylmercury increases with concentration of FA and pH.
