Abstract

The concentration of carbon monoxide in the air of 67 iron, steel, or copper alloy foundries using sand molding was measured. About 1,100 carbon monoxide determinations were made. High concentrations of carbon monoxide were found in the area around the cupolas and the casting sites in iron foundries. The blood carboxyhemoglobin levels of 145 workers from iron foundries were measured. The carboxyhemoglobin level of 6% was exceeded in 26% of the nonsmokers and in 71% of the smokers.

摘要

对67家采用砂型铸造的铁、钢或铜合金铸造厂的空气中一氧化碳浓度进行了测量。共进行了约1100次一氧化碳测定。在铸铁厂的冲天炉和铸造场地周围区域发现了高浓度的一氧化碳。对145名铸铁厂工人的血液碳氧血红蛋白水平进行了测量。26%的不吸烟者和71%的吸烟者的碳氧血红蛋白水平超过了6%。
