Résumé :	Nutrient benthic fluxes, as well as sediment phosphorus concentration at the open sea and coastal water stations of the Central and South Adriatic were studied during 1997-98. The fluxes were in the ranges: 0.16-2.67 mmol m(-2) d(-1) (silicate); 0.031-0.164 mmol m(-2) d(-1) (phosphate); 0.51-2.03 mmol m(-2) d(-1) (ammonia); and 1.32-1.62 mmol m(-2) d(-1) (nitrate + nitrite). Silicate flux showed a gradient from the coastal area to the open sea. Ammonia was the main nitrogen species in the flux at the estuary and bay stations, while the sum of nitrate and nitrite was predominant at the open sea stations. Relationships between phosphate and ammonia fluxes (r = 0.699, p
