Gases formed from furan binding agents.


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… (More)
