我国的粉尘职业危害现状及预防对策

Current Status of Occupational Dust Hazard and Its Preventive Measure in China

呼吸性粉尘及其中的游离ＳｉＯ２是导致尘肺病的主要原因。应最大限度地利用国外的研究结果，根据我国国情，加强对呼吸性粉尘控制技术的研究。同时，国内有关部门应尽早建立和完善呼吸性粉尘检测技术，加强监测制度和劳动卫生标准的制定和实施，建立起使经济投入和治理效果最佳的科学评价体系。

The concentration of respirable dust and the free silica content are main factors causing pneumoconiosis.Authors suggest that the available research achievements pertaining dust hazard in industrialized countries should be fully utilized.The control methods for respirable dust should be greatly strengthened according to domestic situation.At the same time,the measurement technology for respirable dust should be set up and accredited by relevant governmental agencies as soon as possible.The monitoring system and the hygienic standard for respirable dust should be set and implemented quickly.The scientific assessment method for obtaining the optimum outcome of investment and cost-benefit should be established.If great efforts were paid in these respects,authors believe that the incidence of pneumoconiosis might be significantly reduced and the dust hazard could be eliminated after years.
