Manufacturers re-engineered the papers without Cadmium but there's no satisfactory alternative which allows the same flexibility of exposure and development to control the image tone/colour.

Kodak where the last major manufacturer to use Cadmium in a B&W paper - Ektalure, probably because the EU banned the use of Cadmium before the US.
