ASP, DSP, NSP and PSP monitoring in ‘mucilaginous aggregates’ and in mussels in a coastal area of the Nothern Adriatic Sea facing Emilia-Romagna in 1988, 1989 and 1991

In this study, monitoring of marine biotoxins in “mucilaginous aggregates” and in mussels from coastal area of Emilia Romagna (Northern Adriatic Sea) in June–August 1988, 1989 and 1991, are reported. Both “mucilaginous aggregates” and mussels were analysed for NSP and PSP in 1988, and ASP, DSP, NSP, PSP in 1989, 1991. Concerning “mucilaginous aggregate” any presence of biotoxins was never detected. In the mussels it was possible to exclude the presence of PSP, ASP and NSP, but very high levels of DSP were shown in all the considered periods, in relation to the presence in the sea water of cells of the Dinophysis genus.
