Table 2: FST concentrations, in \(\upmu\)g STX.2 HCl eqv/Kg (average \(\pm\) SD), in mussels _Mytilus edulis_ obtained from in vivo studies, in the absence of resin or in the presence of the H-form (2 nd set) and Na*-form (3 rd set) resins. At time 0 (day 6 of each experiment), no resin was present. Figure 8: FST clearance results (global values) from live bivalves using H-form resin (**left**) and Na*-form resin (**right**). Natural clearance (without resin) is also presented for each set of experiments.
