Causes of chromate dermatitis in Poland.

A series of 250 consecutive patients with dermatitis and positive patch tests to chromate was divided into three groups: nonoccupational dermatitis (94), occupational dermatitis caused by chromate (132) and occupational dermatitis caused by allergens other than chromate (24). Only 17.2% of patients did not report harmful effects from chromium-tanned leather. Shoes were most often not tolerated. The role of matches in the development of chromate dermatitis is discussed. Observations on ash, household detergents, textiles, wood, tattooing, cement, galvanizing solutions, printer's ink, welding fumes, corrosion inhibitors and oils are described as causes of chromate dermatitis in Poland, as well as the localization of dermatitis and relevance of patch test reactions.
