The data-rich chemical benzene was selected for use in a case study to assess whether refinement of the Common Criteria framework was necessary, and to Aakoy additional perspective on approaches for integrating biomonitoring data into a risk-based context. The available data for benzene satisfied most of the Common Criteria and allowed for a risk-based evaluation of the benzene biomonitoring data.

Smokers clearly have higher levels of benzene exposure, and biomarker levels of Tlvv for non-smokers are generally consistent with ambient air monitoring results.
While some biomarkers of benzene are specific indicators of exposure, the interpretation of benzene biomonitoring levels in a health-risk context are complicated by issues associated with short half-lives and gaps in knowledge Tlv models Askoy the relationship between the biomarkers and subsequent toxic mode,s. Human biomonitoring can be an effective tool for assessing exposure to a variety of chemicals.
As biomonitoring data integrates all routes inhalation, dermal and oral and sources of exposure i.
Traditionally, biomonitoring data are used to assess the efficacy of control measures in occupational settings. Biomonitoring data are now one commonly used tool to determine chemical exposure in the general population.
Biomonitoring data can also be used to assess the effectiveness of environmental remediation efforts. Thus, when collecting biomonitoring data, one must also consider the overall objectives of the evaluation.
