  <dc:description>&lt;p&gt;&lt;span&gt;A procedure for the determination of 3-trifluormethyl-4-nitrophenol (TFM) in fish tissues is described. Homogenized tissues are extracted with hexane-ethyl ether; the extract is cleaned up by partitioning the TFM from the extracting solvent into 0.1&lt;/span&gt;&lt;i&gt;N&lt;/i&gt;&lt;span&gt;&amp;nbsp;NaOH, acidifying the aqueous solution, and partitioning again with hexaneethyl ether. The TFM is methylated with diazomethane and analyzed by gas-liquid chromatography, using electron capture detection. Recoveries ranged from 75 to 100% from fish muscles that were spiked with 0.01—2.00 μg TFM/g.&lt;/span&gt;&lt;/p&gt;</dc:description>
