Mercury is a chemical element with the symbol Hg and atomic number 80. It is also known as quicksilver or hydrargyrum ( < Greek "" "water" and "" "silver"). A heavy, silvery d-block element, mercury is the only metal that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is bromine, though metals such as caesium, francium, gallium, and rubidium melt just above room temperature.

Recycling Rates of Metals report would certainly benefit from greater metals recycling. Among the least-recycled metals are tellurium and gallium, which are used in solar cells, and lithium, which is a key component of the batteries in electric cars. Stocks of these metals are often tied up in old gadgets, such as out-of-date mobile phones, which people often leave in a cupboard and forget about. The report’s authors concluded that appropriate recycling infrastructure should be developed, supported by policy instruments such as research and development, economic incentives and capacity-building activities.
