In vitro permeation of palladium powders through intact and damaged human skin.

•We tested in vitro Pd powders permeation trough intact and damaged human skin.•The effect of an early decontamination with a common cleanser was assessed too.•After 24 h exposure Pd solution permeates both skin types.•Damaged skin protocol enhances Pd permeation.•Intact skin early decontamination reduces both Pd penetration and permeation.
