TL;DR: The most crucial issues will be discussed in this review of classical and emerging analytical methods based on chromatographic or immunochemical techniques, the validation of official methods for enforcement, and the limitations and future prospects of the current methods.

TL;DR: The results indicate that the novel method (limit of quantification: 4 mg SO2 L(-1)) is well suited for the cost-efficient monitoring of regulatory limits.

TL;DR: It is shown that paper does not provide an appropriate barrier against migration of semipolar compounds such as phthalates, and the air space itself otherwise effectively prevents migration of the less volatile phthalate esters under the applied conditions.

TL;DR: A novel approach for the detection of TA in cereals by liquid chromatography-ion-trap multistage mass spectrometry after derivatization with 2,4-dinitrophenylhydrazine is described.

TL;DR: It was shown that all animal and human liver microsomes led to the formation of up to three different mono-O-glucuronides with significant interspecies differences, and consistent in vitro data on DON glucuronidation are lacking.
