Cobalt-containing alloys and their ability to release cobalt and cause dermatitis
Cobalt, nickel, and chromium are important skin sensitizers. However, knowledge about cobalt exposure and causes of cobalt sensitization is limited. To study release of cobalt, nickel, and chromium from some cobalt-containing hard metal alloys and to test reactivity to the materials in cobalt-sensitized patients. Discs suitable for patch testing were made of some hard metal alloys. Cobalt, nickel,
