title: [Plankton from the Riva Trigoso Bay(Ligurian Sea): presence of various trace elements].
abstract: Between March and June 1989 zooplankton and sea-water samples were taken in three different areas of Riva Trigoso Bay (eastern Ligurian Sea) every two weeks. The analysis of eight trace elements (Cd, Co, Cr, Cu, Fe, Ni, V, Zn) was conducted by means of a graphite furnace atomic absorption spectrophotometer (GFAAS). Biological material values resulted to be limited and quite homogeneous in all metal species thus with no apparent influence from sampling area or time. Observed concentrations (ng/g dry weight) ranged between 12 and 45 for Cd, 52 and 117 for Co, 30 and 71 for Cr, 428 and 1063 for Cu, 730 and 1440 for Fe, 265 and 512 for Ni, 361 and 510 for V, and 1403 and 2499 for Zn. Sea-water values confirmed the results of biological material thus testifying a particularly interesting environmental condition due to low contamination level detected in this part of the coast.
