\n“Later, miners in Saxony encountered what appeared to be a copper ore but found that processing it yielded only a useless slaglike material. They considered it bewitched and ascribed it to the devil, \u201cOld Nick.\u201d Thus, it became known as kupfernickel (Old Nick\u2019s copper). It was from this ore, studied by Axel Fredrik Cronstedt\uff08\u30af\u30ed\u30f3\u30b9\u30c6\u30c3\u30c8\u3001\u9271\u5c71\u5b66\u306e\u7956\uff09, that nickel was isolated and recognized as a new element in 1751.”

\n“The hazards of Ni(CO)4 are far greater than that implied by its CO content, reflecting the effects of the nickel if released in the body. Nickel carbonyl may be fatal if absorbed through the skin or more likely, inhaled due to its high volatility. Its LC50 for a 30-minute exposure has been estimated at 3 ppm, and the concentration that is immediately fatal to humans would be 30 ppm. Some subjects exposed to puffs up to 5 ppm described the odour as musty or sooty, but because the compound is so exceedingly toxic, its smell provides no reliable warning against a potentially fatal exposure.”
