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
Food safety-risk analysis health effects resulting from human exposure to foodborne hazards." The most important aspect of risk assessment in relation to food safety is that it should be rooted in scientific data. Sources of data should be assembled in a systematic manner and should stem from valid scientific studies and communities across the world. A proper risk assessment can be described as being objective and unbiased, with absolute transparency. When at all possible, the assessment should remain independent of risk management as to preserve the integrity of the science and not have influence from regulatory policy and values.
