The objective of the present investigation was to study the influence of the occupational nickel exposure on the concentration of nickel in nasal mucosa, plasma and urine. Plasma, urine and biopsy specimens of nasal mucosa from 318 nickel workers, 15 retired nickel workers and 57 non-exposed controls were analyzed for nickel by atomic absorption spectrometry. The results showed that nickel expo...

Although nickel is an essential element for animal nutrition, the physiological role of nickel is not yet established. Pathological alterations of nickel metabolism are recognized in several human diseases. The diverse clinical manifestations of nickel toxicology include: (1) acute pneumonitis from inhalation of nickel carbonyl, (2) chronic rhinitis and sinusitis from inhalation of nickel aeros...

Everyone who has reached the age of discretion is, unless the contrary is proved, presumed by law to be sane and to be accountable for his actions. This is the doctrine of mens rea. ‘Actus non facit reum nisi mens sit rea’  the deed does not make a man guilty unless his mind is guilty. This is the fundamental basis of English law. For to make a man liable to imprisonment for an offence that he...

Key Points Fire  Elemental nickel dust and nickel carbonyl are flammable  Nickel is incompatible with acids, oxidizing agents and sulphur  Nickel and nickel carbonyl react violently with oxidants  Nickel and nickel compounds emit toxic fumes and vapours of nickel carbonyl when heated to decomposition  In the event of a fire involving nickel carbonyl, use fine water spray and gas tight kit ...

This review gives an overview on the analysis of inorganic nickel species and their toxic effects. Based on the analytical procedure applied inorganic nickel species are usually classified in soluble, sulfidic, metallic and oxidic nickel fractions. Only few works were attempting a chemical characterization of the different nickel compounds in each fraction. This general classification in four n...
