Abstract
The environmental consequences of the use of MMT (methylcyclopentadienyl manganese tricarbonyl) on the different components of an experimental freshwater ecosystem have been studied by following the evolution of their manganese concentrations. The results have been compared with those obtained with inorganic manganese in the same experimental conditions.
In the sediments, the quantities of MMT and Mn(i) are accumulated in the same proportion but the accumulation of MMT is located only at the surface. On the other hand, in living organisms (plant, fishes), the accumulation of MMT is, compared with that of Mn(i), nearly ten times higher.
The accumulation of MMT, as well as that of Mn(i), seems to be strongly dependent on whether the medium is stirred or not.
