Period 6 element point of −38.83 °C and boiling point of 356.73 °C, mercury has one of the narrowest ranges of its liquid state of any metal. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is mostly obtained by reduction from cinnabar. Cinnabar is highly toxic by ingestion or inhalation of the dust. Mercury poisoning can also result from exposure to water-soluble forms of mercury (such as mercuric chloride or methylmercury), inhalation of mercury vapor, or eating seafood contaminated with mercury. Mercury is used in thermometers, barometers, manometers, sphygmomanometers, float valves, mercury switches, and other
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.
