催化剂生产中,工人接触的粉尘主要含铁、镍、铬、钒、锌、铜等金属(以金属氧化物形式存在)。为了解金属粉尘对作业工人肺功能的慢性影响,我们对我厂催化剂分厂的操作工进行了肺功能测定。现将结果报告如下。 对象与方法 一、对象 (一)观察组:催化剂分厂接触金属粉尘的工人
In the production of the catalyst, the dust that the workers contact mainly contains iron, nickel, chromium, vanadium, zinc, copper and other metals (in the form of metal oxides). To understand the chronic effects of metal dust on lung function of workers, we performed lung function tests for operators of our plant catalyst plant. The results reported below. Objects and methods First, the object (A) observation group: catalyst factory workers exposed to metal dust
