ICCL - Caribbean Ports, Inland Logistics, and the Panama Canal Expansion: A Mode and Port Choice Analysis.
Lecture Notes in Computer Science, 2019Co-Authors: Nicolas Gomez-jacome, Guisselle Garcia-llinas, Carlos D. Paternina-arboleda, Miguel Jaller-marteloAbstract:This paper develops an international freight transport model for predicting the importers’ behavior in the port/path-choice decisions after the Panama Canal expansion. A real-data case study for Colombian ports was developed assuming that the expansion will reduce the time to cross the canal. Two infrastructure investment projects of the Colombian government were evaluated as likely scenarios. Results show the adequacy of the model for its Predictive Purpose and its usability to carry sensitivity analyses of scenarios. The overriding outcome is that the model could guide governmental decisions on the infrastructures domain by demonstrating their effect in the logistic realm.

Study of ecodynamic persistent organic pollutants and emerging interest halogenated micropollutants in aquatic environments
2017Co-Authors: Lauzent MathildeAbstract:Les PCB (polychlorobiphényles), PBDE (éthers de biphényles polybromés) et OCP (pesticides organochlorés) sont des composés d’origine anthropique classés comme POP (polluants organiques persistants) dont l’usage a progressivement été restreint ou interdit. Ces composés, de par leur caractère ubiquiste, persistant et bioaccumulable, sont néanmoins toujours présents dans l’environnement, d’où l’importance de continuer à étudier leur présence, leur dynamique et leur impact. Du fait de la restriction de leurs usages, d’autres composés sont maintenant utilisés pour les remplacer, tels que les retardateurs de flamme alternatifs (RFA). Ces composés bromés et chlorés ont des propriétés physico-chimiques comparables à celles des POP précités et peuvent potentiellement constituer un danger chimique pour l’environnement. Par ailleurs, les RFA sont attendus à des niveaux de concentration plus faibles que les PCB et les PBDE que ce soit dans les compartiments biotiques et abiotiques. Ainsi, l’un des enjeux de ce travail de thèse était de développer une méthode multi-résidus, associant chromatographie en phase gazeuse et spectrométrie de masse à temps de vol, permettant d’analyser simultanément 17 RFA à des niveaux inférieurs au ng.g-1. Les niveaux et profils de contamination en POP et RFA ont ensuite été renseignés dans les compartiments biotiques et abiotiques de différents systèmes aquatiques contrastés. Le caractère bioamplifiable de ces composés a été étudié grâce à la détermination de facteurs d’amplification trophique (TMF) dans l’estuaire de la Gironde et dans le bassin du Rhône, à l’aide d’outils statistiques innovants. Dans l’estuaire de la Gironde il a été mis en évidence que certains RFA étaient autant voire plus bioamplifiables que certains POP historiques. Par ailleurs, dans le bassin du Rhône, l’utilisation des TMF comme outil prédictif, pour le BDE-47 ou la ΣPBDE-DCE par exemple, a été discutée et parait envisageable dans un cadre réglementaire.PCBs (polychlorinated biphenyls), PBDEs (polybrominated biphenyl ethers) and OCPs (organochlorine pesticides) are anthropogenic compounds classified as POPs (Persistent Organic Pollutants), their use was restricted or prohibited. These compounds are ubiquitous, persistent and bioaccumulative and they are still present in the environment; this is the reason why it is important to continue the study of the fate and impact in the environment. Due to their usage restriction, other compounds are now used to replace them, such as alternative flame retardants (RFAs). These brominated and chlorinated compounds have physicochemical properties comparable to those of POPs and can thus be potentially hazardous to the environment. In addition, RFAs are expected to occur at lower concentrations than PCBs and PBDEs, whether in the biotic and abiotic compartments. Thus, one of the challenges of the present work was to develop a multiresidue method, based on gas chromatography coupled with a time-of-flight mass spectrometer, allowing for the simultaneous analysis of 17 RFAs at levels below ng.g-1. The levels and patterns of POP and RFA contamination were reported in the biotic and abiotic compartments of selected hydrosystems. The biomagnification potential of these compounds was also studied by determining trophic magnification factors (TMF) in the Gironde estuary and in the Rhône basin. In the Gironde estuary, it was shown that some RFA biomagnify as much or more than some historical POPs. Furthermore, in the Rhône basin, the use of TMF for Predictive Purpose, for BDE-47 or ΣPBDEs-WFD for example, was discussed and found possible
