Annual world manufacturing is roughly 8,400 tons. Major mining locations are Spain, Italy, Yugoslavia.Uses of Mercury:Used in thermometers, barometers, fluorescent lamps and batteries.Additional Notes:Causes neurological and also kidney damage and blindness. Additionally associated v birth defects. Very damaging to aquatic life. The is uncovered in paint, batteries, thermometers, electric equipment, fluorescent lights and also plastics. Also used in gold mining industry. Batteries account because that 88% of the mercury contents in municipal heavy waste.
