Period 6 element 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 alcohol-filled, galinstan-filled, digital, or thermistor-based instruments. It remains in use in scientific research applications and in amalgam material for dental restoration. It is used in lighting: electricity passed through mercury vapor in a phosphor tube produces short-wave ultraviolet light which then causes the phosphor to fluoresce, making visible light. Thallium is a chemical element with the symbol Tl and atomic number 81. This soft gray other metal resembles tin but discolors when exposed to air. The
Hungarian Food Safety Office was the scientific risk assessment relating to food safety, taking into account up-to-date scientific findings of recognised international institutions. The scientific risk assessment is based on identifying potential hazards, defining their characteristics, assessing their incidence and frequency and describing the risk. HFSO is responsible for assessing risks relating to concrete events, furthermore by analysing the data of annual official inspections concerning various agricultural, technological, environmental and biological contaminants, pesticide residues and natural toxic substances in raw and processed food. Based on the risk assessment, it forwards a proposal concerning the priority of inspections in the forthcoming period and participates in
