| Resumen |
In the calendering of papers, organic solvents, mainly toluene, are massively used in paints and adhesives. Personal exposure to toluene and urinary hippuric acid concentration (HA) were measured among exposed workers in a small-size calendering factory (study I). Toluene exposure ranged from 164 to 263ppm and the level of HA ranged from 4967 to 9759mg/g Creatine (mg/gCn). HA was also measured among 205 workers in 22 calendering factories in Osaka prefecture (study II). The level of HA was the highest in vinyl resin painting workers (mean: 2658mg/gCn), followed by laminate coating workers, press workers, miscellaneous exposed workers and clerks. The maximal level of toluene exposure in vinyl resin painting was estimated to be 325ppm on the basis of the HA level. Since the values of HA in 8 press workers (47%), 5 miscellaneous exposed workers (21%) and 12 clerks (55%) were beyond the range for nonexposed persons (709mg/gCn). The air in the calendering factories must have been generally contaminated by toluene. |
