Industrial Toxicology

W'ITH the increasing rate at which new chemicals are being introduced to industry, it has become more and more apparent that the toxicologist must try to discover at least the basic principles upon which to determine by an examination of its formula the toxicity of any aiven substance. Up to now these principles have been elusive and our knowledge is fragmentary in the extreme. The replacement ...

Exposure tests in industrial toxicology.

The purpose of exposure tests for industrial poisons or other hazards is to determine if sufficient quantities of the harmful agent are being ( or have been) absorbed to cause intoxication. In interpreting such tests, the three major factors which determine whether or not intoxication occurs should be considered. The first ofthese is the time factor. Over a short period the probability of intox...

The Chemistry and Toxicology of Depleted Uranium

Natural uranium is comprised of three radioactive isotopes: 238 U, 235 U, and 234 U. Depleted uranium (DU) is a byproduct of the processes for the enrichment of the naturally occurring 235 U isotope. The world wide stock pile contains some 11⁄2 million tons of depleted uranium. Some of it has been used to dilute weapons grade uranium (~90% 235 U) down to reactor grade uranium (~5% 235 U), and s...
