title: Bioaccumulation and toxic effects of elevated levels of 3,3',4,4'-tetrachloroazobenzene (33'44'-TCAB) towards aquatic organisms. III: Bioaccumulation and toxic effects of detrital 33'44'-TCAB on the aquatic snail, Indohiramakigai (Indoplanorbis exustus).
abstract: The polychlorinated aromatic compound 3,3',4,4'-tetrachloroazobenzene (33'44'-TCAB) is a contaminant of many 3,4-dichloroaniline (3,4-DCA) based herbicides, and of agricultural soils. In this study, the aquatic snail Indohiramakigai (Indoplanorbis exustus) was exposed to detrital 33'44'-TCAB. The snails absorbed 33'44'-TCAB from their environment, but only to a maximum level of approximately 287 ppb (whole body basis). This level of 33'44'-TCAB did not appear to cause any harmful effects.
