Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. conducted a standardized study on the gas chromatography method for the determination of acetic anhydride in the air, and conducted a labor hygiene survey on the workshop of a factory producing acetic anhydride. The samples were collected from the places where workers in the acetic anhydride production workshop often stayed, and analyzed by gas chromatography. The average concentrations of acetic anhydride in the air at the two operating sites of the finished product packaging and the pump room were 2.3.1 mg/m3 and 2.6.0 mg/m3, respectively. The concentration range 19.6~31.5mg/m3, the incidence of dry eye, eye burning pain, tearing and other symptoms in the workers was significantly higher than that in the control group and other types of workers.
