Mercury (element) polluted water. They arise by a process known as biomethylation. Mercury is used primarily for the manufacture of industrial chemicals or for electrical and electronic applications. It is used in some thermometers, especially ones which are used to measure high temperatures. A still increasing amount is used as gaseous mercury in fluorescent lamps, while most of the other applications are slowly phased out due to health and safety regulations and is in some applications replaced with less toxic but considerably more expensive Galinstan alloy. Mercury and its compounds have been used in medicine, although they are much less common today
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
