Effect on TTX detector signal and TTX recovery in different C. gigas matrices.
| Matrix | r2 | MM/Solvent Slope (%) | TTX Recovery Mean ± s.d. and (RSD) 1 |
|---|---|---|---|
| Intravalvular fluid | 0.997 | 104 | 91 ± 6 (7%) |
| Mantle | 0.999 | 100 | 86 ± 8 (9%) |
| Gills | 0.996 | 123 | 81 ± 6 (7%) |
| Whole flesh 2 | 0.995 | 117 | 76 ± 6 (8%) |
| Whole flesh 3 | 0.998 | 74 | 66 ± 2 (4%) |
| Adductor | 0.999 | 83 | 68 ± 3 (5%) |
| Digestive gland | 1.000 | 55 | 60 ± 5 (8%) |
| Palp | 0.997 | 55 | 37 ± (12%) |
1 Mean percentage recovery of TTX ± standard deviation (s.d.), spiked at a target concentration of 25 µg/kg in tissues and 50 ng/mL in intravalvular fluid, and the corresponding relative standard deviation (RSD); 2 TTX recovery in the whole flesh collected in March 2020; 3 TTX recovery in the whole flesh collected in May 2019.
