Fig. 3.

Primitive-mantle-normalized trace-element patterns of asbestos bodies and ferruginous protein bodies. a, First leachates with 0.06 M HCl. b, Second leachates with 1 M HCl. c, Bulk compositions (a+b+residues). In a, b and c, element abundances are normalized to 27 wt% of Fe (4000 Fe atoms retained in one ferruginous protein, ferritin).³¹⁾d, Bulk compositions normalized to mass of dry lung used for the asbestos body extraction. Broken line indicates detection limits of the method of analyses. The PM-normalized abundances are depicted as pattern for which the trace elements are arranged in order of their incompatibilities to the silicate mantle increasing from left to right.²⁶⁾
