Tungsten - Precautions

Precautions

Because tungsten is rare and its compounds are generally inert, the effects of tungsten on the environment are limited. The median lethal dose LD50 depends strongly on the animal and the method of administration and varies between 59 mg/kg (intravenous, rabbit) and 5000 mg/kg (tungsten metal powder, intraperitoneal, rats).

Famous quotes containing the word precautions:

    We must take precautions against being prematurely honed sharp—since at the same time we are being prematurely honed thin.
    Friedrich Nietzsche (1844–1900)

    The aim of every political constitution is, or ought to be, first to obtain for rulers men who possess most wisdom to discern, and most virtue to pursue, the common good of the society; and in the next place, to take the most effectual precautions for keeping them virtuous whilst they continue to hold their public trust.
    James Madison (1751–1836)

    It is so manifestly incompatible with those precautions for our peace and safety, which all the great powers habitually observe and enforce in matters affecting them, that a shorter water way between our eastern and western seaboards should be dominated by any European government, that we may confidently expect that such a purpose will not be entertained by any friendly power.
    Benjamin Harrison (1833–1901)
