| Les précédentes études réalisées par l'Institut Pasteur de Lille dans le cadre des conventions de recherche IFREMER - REGION Nord Pas de Calais ont mis en évidence : - Une contamination des sédiments marins et des mollusques, par des métaux lourds aux abords des trois grands ports de Boulogne, Calais et Dunkerque et de leurs dépôts de dragage, - L'importance des apports de métaux lourds et de quelques micropolluants organiques lors du rejet en mer des déblais de dragages portuaires. L'apport annuel moyen est ainsi d'environ 1500 tonnes de métaux (Pb, Cd, Zn, Cu, Hg, Ni, Cr, Mn), une tonne d'hydrocarbures polycycliques aromatiques (HPA) et 0,3 t de polychlorobiphényles (PCB). |

| The work carried out made it possible to better understand the devices of training, the knowledge of the training and development stakeholders, their expectations in the domainof organic farming. If the general principles and techniques of organic farming are fairly well known, their variation in practice is not easily normative. The courses, primarily based on knowledge transfer, are not very effective and the surveyed actors highlighted the value of networks and non-formal trainings. Proposals for changing devices are presented being based on such an innovative action in the Loire Valley with teachers and trainers. The issue of the integration of e-learning in these devices is presented with its potentialsand limits. The issue of educational resources... |
