Chemical contamination of the Seine estuary by organic contaminants (PAH, PCB, pesticides) was studied to determine their geochemical sources, concentrations, behaviour and fate. The results show that the Seine is one of the most contaminated estuaries in Europe. The contaminants studied showed highly contrasting geochemical behaviours during their transport in the estuary. The triazine herbicides and their degradation products transit conservatively in a dissolved state, in the estuary. PCBs have complex dynamics. The estuary's chronic, high contamination raises the question of its effects on organisms and ecological resources.
