Dissolved Organic Carbon Interactions with Mercury...

- Major fractions of the DOC from select locations were isolated and characterized.

- These fractions are composed of different types of organic compounds that interact differently with mercury.

- Compared with isolates from the 2BS site, F1 isolates generally

-were more aromatic

-had higher molecular weights

-contained more organic sulfur

- These properties control organic matter reactivity within mercury.
