为了解手工金属弧—不锈钢(MMA/SS)焊接烟尘中铬(Cr)混合物与其它成分(Fe、Mn、Ni、F)的关系,进一步评价焊接工人的职业暴露状况,于1987～1990年对波兰的1家动力配件制造厂(A)、1家化工厂(B)和2家金属材料厂(C、D)的焊接车间进行了调查。上述4家工厂车间均有通风装置,而C厂在焊接室配有排气设备。工厂工人为8h工作制,每
In order to understand the relationship between chromium (Cr) mixture and other components (Fe, Mn, Ni, F) in hand-held metal arc-stainless steel (MMA / SS) welding soot, the occupational exposure status of welders was further evaluated. A power plant in Poland (A), a chemical plant (B) and two metalworking plants (C, D) were surveyed. The four factories have ventilation plant workshop, and C plant in the welding chamber with exhaust equipment. Factory workers for the 8h working system, each
