The polychlorinated aromatic compound 3,3',4,4'-tetrachloroazobenzene
(33'44'-TCAB) is a contaminant of 3,4-dichloroaniline (3,4-DCA) based
herbicides, and of agricultural soils. In this study, the Japanese Med
aka (Oryzias latipes) was exposed 0.5-2500 ppm 33'44-TCAB through its
diet. There was a distinct trend towards increased mortality and incre
ased body burdens of 33'44'-TCAB with increasing 33'44'-TCAB charge in
the food. At the highest levels of exposure, there was a significant
number of excess deaths compared to control groups.
