Objective:
The control room A and B employees are a high risk of benzene exposure, because they work close to the waste pit which is a source of benzene. This study is to analyze the magnitude of the health risk of benzene exposure to all employees.
Methods:
The data of this study were obtained from interviews and the results of environmental quality of PT X. Data were analyzed using Environmental Health Risk Analysis (EHRA) method which compared with RfC for non-carcinogenic effects and CSF for carcinogenic effects.
Results:
The results of individual calculations for the non-carcinogenic and carcinogenic effect of benzene are at a dangerous level in both real time and lifetime exposure.
Conclusions:
In the calculation of carcinogenic and non-carcinogenic risk exposure in real time, half the populations are at risk of being affected and in lifetime the entire populations are at risk of being exposed to these effects.
