检查接触三氯化磷(PCl_3)64名工人和70名对照组人群,并测定生产车间空气中PCl_3的浓度。发现PCl_3对工人上呼吸道有一定刺激作用,并导致慢性鼻炎、咽炎和咳嗽,与对照组比较有明显增高。提示长期接触低浓度PCl_3可引起人体不同程度的上呼吸道损害。但尚未发现有肺、肝、肾损害。
Sixty-four workers exposed to PCl_3 and 70 control subjects were examined for PCl_3 concentration in the air of the workshop. PCl_3 found on the upper respiratory tract workers have a certain stimulating effect, and lead to chronic rhinitis, pharyngitis and cough, compared with the control group was significantly higher. Prompted long-term exposure to low concentrations of PCl_3 can cause varying degrees of upper respiratory tract damage. However, no lung, liver or kidney damage has been found.
