Abstract

By the accident of explosion at a petrochemical plant in Jilin city of China, on November, 13th, 2005, about 100 tons of nitrobenzene, benzene and aniline were spilled into the Songhua river flowing in the north-east area of China. Therefore, nitrobenzene in fish samples collected from the Songhua river in Harbin city after passing of contaminants were determined. A cyclic steam distillation apparatus for extraction and concentration of nitrobenzene in fish samples was used, and the preparation and pretreatment of a fish samples and extraction conditions were investigated. As a result, relatively high concentration of nitrobenzene was found out in fish samples collected in March and October of 2006. Nitrophenol, one of the expected products by metabolism of nitrobenzene in fish samples was also determined. o-, m-, p-nitrophenol were detected in fish samples. © 2009 The Japan Society for Analytical Chemistry.
