No lesions were observed apart from a few small areas with erosions and mild hyperkeratosis, which are normally present in the skin of piglets.
These values were determined from epidemiology studies on workers exposed to silver dust, where few adverse health effects were observed apart from the development of argyria [ 46].
No significant gross lesions were observed, apart from a moderate amount of subcutaneous oedema in the cranial region of the trunk, and multiple erosions of the tongue epithelium.
As regards their appearance, no deformations were observed apart from the pilei in Pleurotus strains, which presented slightly lighter colours in increased TPOMW concentrations (40% and 60% rates).
No gross anatomical defects were observed apart from the smaller size of their brains in the AP axis (Supplementary Fig. 4 and data not shown).
No specific findings were observed, apart from bleeding in an area of the inner wall of the left chamber and atrium of the heart, some bleeding in the lungs and fat deposition in one liver lobule.
