Fate of heavy metals in experimental aquatic food chains: uptake and release of Hg and Cd by some marine organisms: role of metallothioneins

When trying to model aquatic food webs one might be tempted to associate a flux of pollutants - say heavy metals - to the fluxes of carbon or nitrogen linking the different parts of the system. Restricting to major questions, one needs know the level of contamination of prey and predator, the rate of entry from food or directly from water, the rate of loss, the possible effects of abiotic factors (chemical speciation, partition of the metal between water column and suspended particulate matter, temperature,, salinity, oxygen content, etc.). Toxicity must be evaluated at all levels including man and terrestrial animals. The task seems enormous and laboratory experiments only give a partial answer. However, they should be planned with the aim to understand the general scheme and to probe real systems for assessment, asking pertinent questions. The data briefly presented here have been collected with this general framework in mind
