Objective:
benzene; Air pollution; Risk assessment in the air of workshop and validate the methods.
Methods:
Expert-reference, BAYES statistics and expert-measurement were separately used to estimate benzene concentration in a slurry-applying workshop and modeling workshop of a rubber factory. The estimations were compared with current newly monitored data.
Results:
The estimated averages of expert-reference, BAYES statistics and expert-measurement were 100.0, 16.9, 33.2 mg/m3 respectively for the slurry-applying workshop and 100, 156, 115 mg/m3 for the modeling workshop. No significant difference was observed between the estimations and validating sample except to that of the expert-reference for the former.
Conclusion:
BAYES statistics and expert-measurement were precise and expert-reference was candidate if no measurements in spite of its subjectivity.
