✦ Synopsis

Traces of 10 nitrobenzenes in environmental samples such as river water, sediment and fish were determined by capillary gas chromatography-mass spectrometry (GC-MS) involving liquid-liquid extraction, steam distillation and column clean up procedures. The nitrobenzenes could be determined in water within the range 0.3-0.9 ng/ml with relative standard deviations (R.S.D.s) of l.O-6.9%. The detection limits of the nitrobenzenes in water, sediment and fish samples were 0.12-0.23 ng/ml, 1.9-10.9 rig/g and 2.0-8.1 rig/g,, respectively. Their recoveries from river water, sea water, sediment and fish samples were 86-133%, 87-133%, 87-111% and 61-137% with R.S.D.s of 1.3-3.8%, 0.3-3.8%, 2.4-12.5% and 2.0-16.9%, respectively.
