Mercury Removal . Mercury is present at traces level in natural gas and condensates and is dissolved respectively in the hydrocarbons gas phase or in the hydrocarbons liquid phase. It is important to highlight that mercury is mainly present under its elemental form (Hg 0) in natural gas and associated condensates.

"Mercury-free" means that the office does not place new amalgam fillings. "Mercury-safe" means they follow a strict protocol to protect patients, staff, and the environment. If a dentist is knowledgeable and understands mercury biochemistry, it is likely they will take the removal process seriously.

However, the content of C O group and C O group were barely changed after Hg 0 removal (Table S4). This meant that C O group was not involved in mercury removal process. The possible reason was that Fe 3+ species and C Br group had priority in Hg 0 adsorption due to their higher reactivity than C O group.
