铸造工人作业场所空气品质之研究结果。给出了不同生产性质铸造厂作业场所粉尘含量和有害物质含量的测定结果。值得注意的是，铸造区工作区空气中的粉尘含量超过了所有工作场所的最大允许浓度，其中大规模生产车间的超标量最大。接触粉尘最多的是铸件修整工、清洁工和铸件技术员。作业区空气中还存在一氧化碳、氮氧化物、苯酚、甲醛等有害物质，其含量取决于所采用的工艺流程。
The results of the study of air quality on workplaces of foundrymen. The results of measures of dust content and content of harmful substances in the workplace areas at foundries with different nature of production are given. It is noted that the dust content in the air of the working area of the foundry areas exceeds the maximum permissible concentrations at all workplaces, with the largest excess noted in the mass production shops. The highest exposures to dust are castings dressers, cleaners and castings technicians. The harmful substances such as carbon monoxide, nitrogen oxides, phenol, formaldehyde, etc. are also were found in the air of the working zones, the content of which is determined by the applied technological processes.
