Calcium, phosphorus and sulphur content (μg g−1 dry weight) of natural and decalcified (decalc.) wool fibres and sei, humpback and minke whale baleen bristles measured using AAS. (All values are based on a single sample, except for the natural minke baleen values, which are an average of values from two samples.)

| decalc. wool | <32 | 120 | 32 000 |
| sei | 41 000 | 18 000 | 23 000 |
| decalc. sei | 180 | 390 | 28 000 |
| humpback | 7900 | 2900 | 39 000 |
| decalc. humpback | 670 | 780 | 34 000 |
