Abstract

Cobalt is a frequent cause of contact allergy, often seen together with allergy to nickel or chromium. Workers in the hardmetal, construction, and electronics industries and dental technicians, among others, are often allergic to cobalt.

The clinical relevance of patch test reactivity to cobalt is often difficult to establish. Scarce knowledge about sources of skin exposure contributes to the difficulties.

Cobalt has broad applications. Cobalt-containing materials such as hardmetals, alloys, coatings, and compounds have different ability to release cobalt ions upon skin contact and to cause dermatitis.

Quantification of cobalt on the skin by wipe sampling, a new spot test for identifying cobalt release, and assessment of cobalt release from materials immersed in artificial sweat, will increase knowledge and facilitate prevention of cobalt allergy.

Cobalt and cobalt compounds cause occupational lung disease and they are classified as probably and possibly carcinogenic, and as toxic to the environment.
