Mercury (element) is used in thermometers, barometers, manometers, sphygmomanometers, float valves, mercury switches, mercury relays, fluorescent lamps and other devices, though concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely phased out in clinical environments in favor of alternatives such as alcohol- or galinstan-filled glass thermometers and thermistor- or infrared-based electronic instruments. Likewise, mechanical pressure gauges and electronic strain gauge sensors have replaced mercury sphygmomanometers. Mercury remains in use in scientific research applications and in amalgam for dental restoration in some locales. It is also used in fluorescent lighting. Electricity passed through mercury vapor in a fluorescent
Toxic Substances Control Act of 1976 safety standard. However, the EWG regarded CSIA as moving in the right direction because the EPA would have gained more authority to review existing chemicals and order companies to provide any relevant safety data about a specific chemical in question. Earthjustice further called for the final result of TSCA reform to be one that adequately protected workers continually exposed to hazardous chemicals, vulnerable populations, and communities most at risk because of high exposure to toxic chemicals. The CSIA would have required states to co-enforce any requirements laid out by the EPA, i.e. to have funding and man-power to enforce all
