    Facial flushing and other symptoms were reported by 19 of a group of 102 men who worked with dimethylformamide (DMF). Twenty-six of the 34 episodes occurred after the workers had consumed alcoholic drinks. The metabolite N-methylformamide (MF) was detected in the urine on 45 occasions, the highest recorded concentration being 77 microliter/litre. The highest recorded concentration of DMF in air was 200 ppm. The DMF-ethanol reaction is possibly attributable to the inhibition of acetaldehyde metabolism, probably by MF.
