炭黑是国民经济中不可缺少的化工原料,它主要由炭元素组成(占90～99％),呈直径很少的球形颗粒。吸入炭黑粉尘是否能引起尘肺改变,尚有不同见解。从动物实验的角度来看,国内报导有大鼠、家兔及狗的实验资料,尚未见有猴的实验资料。本文对自然吸入炭黑粉尘的实验猴作初步病理观察,并与国外报导作比较。 Carbon black is an indispensable chemical raw material in the national economy. It is mainly composed of carbon elements (90-99%) with spherical particles with very small diameter. Whether inhalation of carbon black dust can cause pneumoconiosis changes, there are different opinions. From the animal experiment point of view, the domestic reports of rat, rabbit and dog experimental data, but no monkey experimental data. In this paper, a preliminary pathological observation of experimental monkeys naturally inhaled carbon black dust was made and compared with foreign reports.
