An enantioselective heart-cut two-dimensional liquid chromatography-atmospheric pressure photoionization-tandem mass spectrometry method was developed for the analysis of 25 methylsulfonyl polychlorinated biphenyl metabolites in tissue extracts. Enantioseparation was achieved for 9 out of the 10 chiral analytes in less than 91 minutes, improving upon previous gas chromatography-based methods. Use of a pyrenyl-ethyl silica column in the first dimension enabled separation of all but two pairs of isobaric analytes. Limits of detection of 0.01 to 1.73 ng on-column were achieved. The precision and accuracy were within acceptable limits, but poor sensitivity was achieved for several meta-methylsulfonyl-substituted congeners. Despite this limitation, the method was successfully applied to the analysis of Greenland sledge dog (Canis familiaris) plasma and adipose tissue extracts. Concentration and enantiomer fraction data are presented. None of the target analytes were detected in Norwegian glaucous gull (Larus hyperboreus) plasma extracts.

Cette étude s’intéresse aux modes de transport terrestre utilisés pour les biens et marchandises dans l’ancienne Égypte. On en dénombre plusieurs, dont les plus importants sont la palanche, la barre de portage, le traîneau, et le transport à dos d’âne. Cette recherche s’appuie principalement sur des ressources documentaires iconographiques et plastiques, provenant de mastabas et d’hypogées datés de l’Ancien et du Moyen Empire. Elle a pour enjeu de préciser les conditions d’utilisation des différents modes de transport, tant sur un plan chronologique, que sociologique, ou topographique. / This study deals with means of land transport used for goods and merchandises in ancient Egypt. We can count a few, among which the most important are yoke, carrying pole, sledge and donkeys. This research is mainly based on iconographic and sculptural documentary resources from mastabas and hypogea dating from the Old and Middle Kingdom. Its main concern is to explain the conditions of use of the different means of land transport, on a chronological, sociological as well as on a topographical level.
