Analytical Methods for Trichothecenes Surveillance — An Overview Over the Period 1990—2000
This article reviews some aspects of analytical methods used to determine the occurrence of type A and B trichothecenes in grains and foodstuffs and their trends during the decade 1999—2000. A pronounced tendency to use extraction solvents less toxic than chloroform became evident. There was not a p...
