关于光敏作用的研究,虽然在本世纪初早已开始,但直到近20年由于光敏性疾患的明显增加,这一问题才引起人们的重视。近十几年来由于光敏性皮炎引起的严重损害,已非罕见。1971年Epstein就指出作为药品、化妆品、肥皂和其他目的使用的化学品引起的光敏反应,已成为一个重要的医学和社会经济问题。从劳动卫生观点来看,外源性化学品的光敏作用,与石油化工及其有关的行业和长期室外劳动者更有较为密切的关系。人们在生产和生活中与光敏性物质接触,经光能照射后的光敏反应已成为毒理学中的一个特殊问题。
Although the study on the photosensitivity has already begun early in this century, it has not attracted the attention of the public until nearly 20 years due to the obvious increase of photosensitivity disorders. In the past ten years due to photosensitive dermatitis caused serious damage, is not uncommon. In 1971, Epstein pointed out that the photosensitive reaction caused by chemicals used as medicines, cosmetics, soaps and other purposes has become an important medical and socio-economic issue. From the point of view of labor hygiene, the photosensitivity of exogenous chemicals is more closely related to petrochemicals and their related industries and long-term outdoor workers. People in the production and life contact with the photosensitive material, the photosensitive reaction after light irradiation has become a toxicology in a special issue.
