在碳黑的生产、加工的场地,常会有一些碳黑尘粒,其大小恰宜吸入人的肺中。碳黑的吸入对人的肺功能是否有损害呢?针对这一问题,国外一家从事职业健康问题研究的机构对美国6家生产碳黑的工厂中的913名工人进行了一次断面调查。 调查时,综合考虑每个工种接触碳黑粉尘平均浓度和该工种上工人接触碳黑的工龄两方面因素,以“mg/M~3·月”计算接触量。肺功能用肺
In the production of carbon black, the processing of venues, often have some carbon black dust particles, its size appropriate to inhale the lungs. In view of this problem, a foreign body engaged in occupational health research conducted a cross-sectional survey of 913 workers in six carbon black factories in the United States. During the investigation, the exposure amount was calculated as “mg / M ~ 3 · month” considering both the average exposure of each type of work to the average concentration of carbon black dust and the service life of the workers exposed to carbon black.
