作者为研究合成洗涤剂(CMC)成品粉尘对健康工人的作用特征,调查了阿克拉某洗涤剂厂。该厂产品主要成分是烷基磺酸钠。各车间粉尘浓度超过10 mg/m~3,以包装车间(9.25～17.6 mg/m~3)和成品库(15.2～36.8 mg/m~3)浓度较高。工人主诉有周期性皮肤搔痒、手部皮肤干裂、咳嗽、鼻咽干痒等,绝大多数工人患有上呼吸道和皮肤疾患。作者从包装车间(整班接触)选60名健康女工作研究对象,以30名不接触CMC的女工为对照。两组平均
To investigate the role of synthetic detergent (CMC) finished dust on healthy workers, the authors investigated a detergent plant in Accra. The main product of this plant is sodium alkyl sulfonate. The concentration of dust in each workshop exceeded 10 mg / m ~ 3, and the concentration in the workshop (9.25 ~ 17.6 mg / m ~ 3) and finished product warehouse (15.2 ~ 36.8 mg / m ~ 3) was higher. The workers complained of periodic itchy skin, dry skin and hands, cough, nasopharyngeal dry itch, most workers suffer from upper respiratory tract and skin disorders.
