Because of the world-wide increase in the use of wood, diseases due to exposure to wood dust and substances connected with the wood-processing industry are also likely to increase. Many authors have written about disorders of this kind, ranging from irritative and allergic reactions to cancerogenic effects. There exist a great deal of widely disseminated publications on this subject. Moreover, the various existing synonyms, especially for tropical woods, render more difficult the valuation of published results. The purpose of this review of publications issued in recent years is to represent all known symptoms and disorders due to occupational wood-dust exposure. Furthermore, points that remain unclarified should be shown in order to stimulate further investigations. Recommendations for safety restrictions are also given.
