多年来,各国学者把注意力普遍放在能引起严重尘肺的各种无机粉尘,如矽尘、煤尘、石棉尘等,而忽视了对有机粉尘的研究。随着生产和科学技术的发展,有机粉尘对人体的危害已越来越引起各国学者的注意。但对有机粉尘是否能引起尘肺仍存在争论,对有机粉尘引起机体的病理变化和临床表现的研究正方兴未艾。有机粉尘可分为植物性粉尘(如棉尘、谷物尘、木尘、茶尘等)、动物性粉尘(如羽毛尘、皮毛尘、骨质尘等)和人工有机粉尘(如聚氯乙烯粉尘、树脂粉尘等)三种。有机粉尘可对人体带来多种危害,除可引起上呼吸道粘膜的炎症(包括慢性鼻炎、慢性咽炎和慢性扁桃体炎)、尘源性支气管炎、职业性哮喘外,尚可引起以下几种较严重的疾患: Over the years, scholars from various countries have generally focused their attention on various inorganic dusts that cause severe pneumoconiosis, such as silica dust, coal dust, asbestos dust and the like, while neglecting organic dust research. With the development of production and science and technology, the harm of organic dust to the human body has drawn more and more attention from scholars all over the world. However, whether organic dust can cause pneumoconiosis remains controversial. The research on the pathological changes and clinical manifestations caused by organic dust is in the ascendant. Organic dust can be divided into plant dust (cotton dust, grain dust, wood dust, tea dust, etc.), animal dust (such as feather dust, fur dust, bone dust, etc.) and artificial organic dust (such as PVC dust , Resin dust, etc.) three. Organic dust can bring a variety of hazards to the human body, in addition to cause inflammation of the upper respiratory tract mucosa (including chronic rhinitis, chronic pharyngitis and chronic tonsillitis), dust-borne bronchitis, occupational asthma, can still cause the following types of Serious disorders:
