Absolute toxicities and tissue distribution of toxins in giant clams exposed to G. polynesiensis cells (TB92 strain) based on CBA-N2a data. In each tank, each group of tissues was pooled from three giant clams.
| Tank | Tissue | Absolute Toxicity of Tissue 1 | Tissue Wet Weight [g] (Relative Weight Contribution, %) | Tissue Distribution of Toxins 2 | Tissue Contribution to the Total Body Toxin Content |
|---|---|---|---|---|---|
| 1 | Viscera | 12.2 ± 0.4 | 36 (26%) | 3.2 ± 0.1 | 59% |
| Flesh | 3.0 ± 0.2 | 75 (54%) | 1.6 ± 0.1 | 31% | |
| Mantle | 2.6 ± 0.2 | 28.5 (20%) | 0.5 ± 0.0 | 10% | |
| 2 | Viscera | 13.1 ± 0.8 | 37.5 (25%) | 3.3 ± 0.2 | 71% |
| Flesh | 2.0 ± 0.2 | 72 (48%) | 0.9 ± 0.1 | 20% | |
| Mantle | 1.4 ± 0.2 | 39.5 (27%) | 0.4 ± 0.1 | 9% | |
| 3 | Viscera | 13.6 ± 1.4 | 33.5 (26%) | 3.5 ± 0.4 | 64% |
| Flesh | 3.0 ± 0.1 | 58.5 (45%) | 1.4 ± 0.0 | 25% | |
| Mantle | 2.1 ± 0.3 | 38 (29%) | 0.6 ± 0.1 | 11% |
1 The absolute toxicity of each tissue, expressed in ng P-CTX3C equiv./g tissue, was measured directly from the extracts of each tissue using the following formula: P-CTX3C EC50/sample EC50; 2 The tissue distribution of toxins, expressed in ng P-CTX3C equiv./g whole body, was calculated using the following formula: absolute toxicity × relative weight contribution.
