Health Risk from Exposure to PCDD/Fs from a Waelz Plant in Central Taiwan

This study combined ambient air sampling and biomonitoring data to determine the PCDD/Fs exposure levels and health risk for residents near a Waelz plant. In total, 457 adults completed questionnaires and 48 subjects also gave blood samples. We used the USEPA multimedia model to estimate lifetime exposure and cancer risk. Analytical results show that average atmospheric PCDD/Fs concentrations were 149–285 fg I-TEQ/m 3 and deposition flux was 0.57–116 pg I-TEQ/m 2 -d.
