What is mercury?
Mercury is an element (Hg on the periodic table) that is found naturally in the environment. Mercury emissions in the air can come from both natural and man-made sources. This silver-colored liquid metal can be found in rocks, soil and the ocean. Mercury can be released into the environment through natural processes when volcanoes erupt, rocks erode and soil decomposes.

As a liquid metal at room temperature, mercury has been widely used throughout industry. Man-made sources of mercury include abandoned mines, energy production, sewage, industrial processes, mining, smelting, scrap metal processing and incineration or land disposal of mercury products or waste.
