The amount of mercury deposited in a given area depends on how much mercury is released from local, regional, national, and international sources. Emissions from Power Plants. Since mercury occurs naturally in coal and other fossil fuels, when people burn these fuels for energy, the mercury becomes airborne and goes into the atmosphere. Mercury is found naturally in rock deposits as a native element, and bound to other elements in minerals. Mercury in these forms is referred to as “inorganic mercury.” Under certain conditions, inorganic mercury may combine with one carbon and three hydrogen atoms (CH 3), which is referred to as a methyl group.
