—This study uses target organ-specific hazard index
(TOSHI) and cancer Risk to analyze the health risk for indoor
air pollutants defined in Taiwan Indoor Air Quality
Management Act. The reference concentrations (RfC) refer to
the minimal values among chronic reference exposure level
(REL) developed by OEHHA, guideline values developed by
WHO, threshold limit values (TLV) developed by ACGIH, and
Taiwan Indoor Air Quality Standard. As for cancer unit risk,
the minimal values between OEHH and WHO are considered.
Finally, the method is performed to analyze the health risk of
IAQ in a local hospital, before and after improvement plan,
—Indoor air quality, health risk analysis, hazard
index, reference concentration, cancer risk, unit risk.
