Seston is formed by a living fraction (plankton) and a dead fraction (tripton). Plankton are capable of concentrating large quantities of heavy metals from seawater, and this provides an entry into the marine food web. Tripton also accumulate metals by adsorption on its inorganic particles or by affinity with organic materials. There is information about metal content in mollusks and sediments from the Patagonian coast, but no data are available for seston. In this report the authors present baseline levels of Fe, Zn, Mn, Cu, Cd, Pb and Ni in seston from the San Jose Gulf, a semiarid area with no human-industrial settlement on its coast.
