Organic N-chloramines: chemistry and toxicology.

The stability of aqueous solutions of organic N-chloramines, suspected of contaminating chlorinated water, has been studied. Two factors influence the decomposition of solutions of N-chloropiperidine and N-chlorodiethylamine: a spontaneous decomposition and photodecomposition. Since solutions of these compounds are relatively long-lived, a need for an analytical method for their identification ...

Amanita muscaria: chemistry, biology, toxicology, and ethnomycology.

The fly agaric is a remarkable mushroom in many respects; these are its bearing, history, chemical components and the poisoning that it provokes when consumed. The 'pantherina' poisoning syndrome is characterized by central nervous system dysfunction. The main species responsible are Amanita muscaria and A. pantherina (Amanitaceae); however, some other species of the genus have been suspected f...

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...

Chemistry and toxicology of smokeless tobacco.

In most parts of the world, tobacco is used for smoking, whereas, in India, tobacco is used for smoking as well as in diverse smokeless forms. Absorption of toxic and carcinogenic chemicals in tobacco and other ingredients added to various products are causally associated with several non-communicable diseases including cancer, especially oral cancer, which is the leading cancer among men and t...
