BIOACCUMULATION AND TOXIC EFFECTS OF ELEVATED LEVELS OF 3,3′,4,4′-TETRACHLOROAZOBENZENE (33′44′-TCAB) TOWARDS AQUATIC ORGANISMS . Ⅰ: A SIMPLE METHOD FOR THE RAPID EXTRACTION, DETECTION AND DETERMINATION OF 33′44′-TCAB IN MULTIPLE BIOLOGICAL SAMPLE

摘要

The polychlorinated aromatic compound 3,3′,4,4′-tetrachloroazobenzene (33′44′-TCAB) is a contaminant of 3,4-dichloroaniline based herbicides, but there have been no reports of methods for the quantitative determination of 33′44′-TCAB in biological organisms. In this communication we address this knowledge gap by presenting a method for the rapid extraction, detection and determination of 33′44′-TCAB in multiple biological samples based on the alkaline decomposition of the sample followed by alumina cartridge column chromatography and GC-HRMS analysis . 3,3′,4,4′-tetrachloroazobenzene; biological sample analysis; GC-HRMS.
