The haemolymph concentrations of OA after intra-sinus dosing were best described by a two-compartment open model. The distribution and elimination half-lives were 0.84 and 17.7 h respectively. The apparent volume of distribution at a steady state and the total body clearance were estimated to be 2061 mL kg.sup.-1 and 90.1 mL kg.sup.-1 h.sup.-1 respectively. The bioavailability of OA after an oral administration was 7.9%. The peak haemolymph concentration, the time to peak haemolymph concentration and the elimination half-life after oral administration were 4.20 [mu]g mL.sup.-1, 4 h and 19.8 h respectively. Oxolinic acid muscle and shell levels increased to a maximum (muscle 1.76 [mu]g g.sup.-1 and shell 8.17 [mu]g g.sup.-1) at 4 h post administration and then decreased with the elimination half-life value of 20.2 and 21.9 h respectively. Residual OA in muscle and shell was reduced by 20-30% by each cooking procedure examined.
