[109], Sediments within large urban-industrial estuaries act as an important sink for point source and diffuse mercury pollution within catchments. Mercury is a heavy, silvery-white liquid metal.
Mercury was once used as a gun barrel bore cleaner. The richest mercury ores contain up to 2.5% mercury by mass, and even the leanest concentrated deposits are at least 0.1% mercury (12,000 times average crustal abundance). The price of mercury has been highly volatile over the years and in 2006 was $650 per 76-pound (34.46 kg) flask.

[95], Recent atmospheric mercury contamination in outdoor urban air was measured at 0.01–0.02 µg/m3. Many historic applications made use of the peculiar physical properties of mercury, especially as a dense liquid and a liquid metal: Others applications made use of the chemical properties of mercury: Mercury(I) chloride (also known as calomel or mercurous chloride) has been used in traditional medicine as a diuretic, topical disinfectant, and laxative. [53] After about 1985, all new chloralkali production facilities that were built in the United States used membrane cell or diaphragm cell technologies to produce chlorine.
