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
Toxic injury products, pharmaceuticals and industrial products. Many commonly found natural substances may be toxic. They can be found in our air, water or food supply. The top ten most common environmental toxins are: Avoiding direct exposure to toxins will reduce the risk of toxic injury. For safety reasons, wear personal protective equipment when working near environmental or chemical toxins. Many countries have guides classifying dangerous goods and identifying the risks associated with them, such as Canada's Workplace Hazardous Materials Information System. These guides have been developed to ensure worker safety when handling dangerous chemical toxins. It is also important to maintain
