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 injury Toxic injury A toxic injury is a type of injury caused by toxin. Toxic injuries can cause teratogenic effects, respiratory effects, gastrointestinal effects, cardiovascular effects, hepatic effects, renal effects and neurological effects. They can also lead to various forms of cancer or learning disability. Effects can occur after acute (short-term) or chronic (long-term) exposure, depending on the toxicity of the substance. Those who suffer from Multiple Chemical Sensitivity are at greater risk of toxic injury. In America, May is recognized as Multiple Chemical Sensitivity and Toxic Injury Awareness Month. Every toxic injury or expsoure to a toxin has different effects
