| Popis: | The purpose of this study was to measure the concentration of carbon black and BTEXs at three photocopy centers and to assess the health risk following exposure. Air samples were collected by sampling in the breathing zone of workers during the class and examination periods. The results found that the concentration of carbon black before operation was higher than morning and afternoon in both class and examination periods. These levels are considerably lower than the suggested limited value set by OSHA. Toluene had the highest concentration but did not exceed of recommended exposure limit by NIOSH. The carbon black and toluene concentrations were higher in examination period than during the normal class period. The results from interview indicate that cough and sneeze are the highest symptom among workers. Carbon black and toluene concentrations in photocopy centers should be concerned in terms of indoor air quality and human health. |
