Exposure to Cobalt Can Cause Contact Dermatitis

Cobalt is also a common allergen that is found in many of the same items that contain nickel, thereby making this allergen difficult to pinpoint. It is also found naturally in soil, dust and seawater. In the home, it is most often found in the blue pigments in porcelain, glass, pottery or ceramics, as well as blue and green water color paints and crayons. In the workplace, cobalt is found in cement, bricks and mortars."Combined allergic reactions are not uncommon and represent simultaneous specific sensations to each individual metals as opposed to being reactions to the combination," stated Dr. Fowler. "Whenever possible, patients are encouraged to avoid the allergen, use plastic or wooden items, such as kitchen utensils or scissors, and wear protective clothing and a face mask at their workplace."
