This paper reports on formaldehyde exposure and its health hazards in a melamine manufacturing industry. The mean of workers' exposure was measured according to 3500 NJOSH and was found to be 1.44±O.2l, and 2. 17±O.24 ppm in morning and evening shifts, respectively. For stationary ones it was 1.37±O.20, and 2.06±O.25ppm, respectively. The results show that formaldehyde concentration at the sources (presses) depends on the weight of the resin used, and differences in concentration of various quantities of the applied resin with one another was significant (p<0.05). Based on the results of 272 samples, it was noted that formaldehyde concentration in the evening shift was more than that of the morning shift (p<0.05), and from 3-6 P.M. is at maximum levels, except the polish workshop was less than 10 mg/m3 (TLV -PNOC). In pressing workshops, all particles were respirable, whereas in the polish workshop, respirable particles comprised only 24% of all particles. Exposure to formaldehyde was associated with several symptoms including eye burning, lacrimation, excessive blinking, nose and throat irritation and thirst, which were significantly higher in concentrations over 1 ppm compared with lower concentrations (p<0.05).
Keywords: Formaldehyde, Resin, Exposure, Health.
