Abstract

Furfuryl alcohol and formaldehyde concentrations in the air of coremaking areas of 10 iron and steel foundries were measured. The mean concentration of furfuryl alcohol and formaldehyde was 4.3 cm3/m3 and 2.7 cm3/m3, respectively. Furfuryl alcohol exceeded its threshold limit value (TLV) of 5 cm3/m3 in 22% of the determinations; and formaldehyde (TLV=2 cm3/m3) in 38%. In addition phenol concentration was determined in one foundry; and phosphoric acid concentration, in two foundries. The concentrations of phenol and phosphoric acid were far lower than their TLVs. The question is raised as to whether exposure to furfuryl alcohol and formaldehyde in foundries in combination with exposure to dust and smoking can increase the risk of chronic bronchitis.

摘要

对10家钢铁铸造厂制芯区域空气中的糠醇和甲醛浓度进行了测量。糠醇和甲醛的平均浓度分别为4.3立方厘米/立方米和2.7立方厘米/立方米。在22%的检测中，糠醇超过了其5立方厘米/立方米的阈限值；甲醛（阈限值=2立方厘米/立方米）在38%的检测中超标。此外，在一家铸造厂测定了苯酚浓度，在两家铸造厂测定了磷酸浓度。苯酚和磷酸的浓度远低于其阈限值。由此引发了一个问题，即铸造厂中糠醇和甲醛暴露与粉尘暴露及吸烟相结合是否会增加患慢性支气管炎的风险。
