| Abstract |
An environmental monitoring project is being conducted to determine if TCDD is accumulating in the environment. TCDD is an extremely toxic, chlorocrigenic, and teratogenic material and is a possible contaminating by-product in manufacturing processes utilizing tetrachlorbenzene and in the manufacture of herbicides containing esters of 2,4,5-trichlorophenoxy acetic acid. The single oral LD(50) of this compound in certain species of guinea pigs is six hundred parts per trillion (600 ppt). |
