  • and error corrections of the PDEs for Silver (oral), Gold (oral, parenteral and inhalation) and Nickel (inhalation).

The newly established PDEs:

  • The corrected parenteral PDE for Silver is 15 μg/day.
  • The corrected PDE of Gold by oral, parenteral or inhalation routes is identified as 300, 300, 3 μg/day.
  • The corrected PDE of Nickel by inhalation is now listed with 6 μg/day.
