Results and discussion

Results:
A study performed by the NIOSH in a grinding wheel plant reported a general higher incidence of eye and respiratory tract irritation which was attributed to furfural vapours which were detected at concentrations ranging from 20 -63 mg/m3. Eye irritation, manifested by itching, burning, tearing and/or redness, was reported by 11 of 15 workers. Ten workers noted frequent nasal irritation (stuffiness, dryness or soreness, and in one case, occasional bloody nasal discharge). Seven individuals reported dryness of the mouth or throat (ACGIH, 2001). NIOSH conducted a health hazard evaluation at a manufacturer of aluminium graphite tubes. Irritating effects on eyes, mouth, throat, and nose, and respiratory symptoms were reported. Eleven of the 15 (73%) time weighed average personal breathing zone furfural concentrations (range 0.3-4.2 ppm) exceeded the threshold limit value of 8 mg/m3 (2 ppm). However, the influence of other hazardous substances (respirable particles and phenol) and factors cannot be excluded, but are unknown (NIOSH, 1995). Therefore, the results are not useful for evaluation purposes of furfural.
