Health Risk Analysis of Indoor Air Pollution

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, respectively.
