甲醛是一种重要的化工原料,在工业生产中广泛应用,除甲醛溶液的生产、运输、贮存外,含甲醛产品的生产、加工、使用过程也可接触到甲醛。此外,甲醛溶液也用于医疗、农业等。长期接触低浓度甲醛可引起工人一系列临床症状和体征,但关于接触浓度与临床症状关系资料的报道尚不多见。为此,我们对不同浓度的甲醛作业工人和对照组工人进行了健康检查,进一步探讨其临床症状和接触浓度的 Formaldehyde is an important chemical raw material, widely used in industrial production. In addition to the production, transportation and storage of formaldehyde solution, the production, processing and use of formaldehyde-containing products are also exposed to formaldehyde. In addition, formaldehyde solution is also used for medical treatment, agriculture and so on. Long-term exposure to low concentrations of formaldehyde can cause workers a series of clinical symptoms and signs, but the report of the relationship between exposure concentration and clinical symptoms is still rare. To this end, we conducted a health examination of workers in formaldehyde and control workers at different concentrations to further investigate the clinical symptoms and exposure levels
