Rapid screening procedure for the detection of trichothecenes in plasma and urine.
A rapid and easy procedure to screen for trichothecenes in plasma and urine is presented. The toxins are extracted using a Clin-Elut column, hydrolyzed to their corresponding parent alcohols and cleaned up with a silica cartridge followed by derivatization for gas chromatographic analysis. The detection of any of the parent alcohols in plasma or urine would indicate an exposure to trichothecenes. Recoveries in urine are between 78 and 119% at levels of 50-1000 ng/ml and recoveries in plasma are between 80 and 116% at levels of 50-500 ng/ml. The limit of detection is better than 25 ppb.
