Mercury is indeed a highly toxic element used in industry, in chlor-alkali processes and the plastics industry for example, and in products such as thermometers, dental amalgam, batteries and light bulbs.
Elavhõbe on kahtlemata väga toksiline element, mida kasutatakse näiteks kloorleeliste ja plastitööstuses ning sellistes toodetes nagu termomeetrid, hammaste amalgaamtäidised, patareid ja lambipirnid.
