||Exposure to methyl methacrylate and its subjective symptoms among dental technicians in Tehran, Iran
||2005, Vol.11, No.3, p.283-289. Illus. 11 ref.
||Methyl methacrylate (MMA) and total dust exposures, as well as workers' health symptoms, were investigated in 20 dental laboratories in Tehran, Iran. Time-weighted average (TWA) of MMA and peak concentrations were determined and total dusts were evaluated. Data on health symptoms were collected by questionnaire. There were no significant differences between the TWA of MMA and the peak concentration in different workdays; however, important within-day variations were observed. Cough and skin dryness were the common health symptoms. Smoking and a history of asbestos exposure were factors influencing cough prevalence. Although short-term exposures were found to be lower than the current short-term exposure limit (STEL) of 100ppm, it is argued that the STEL is not low enough to protect technicians against the adverse effects caused by MMA.
