2,3,7,8-tetrachlorodibenzo-p-dioxin levels in adipose tissue of persons with no known exposure and in exposed persons

Abstract Adipose tissue tetrachlorodibenzo-p-dioxin (TCDD) levels were determined for 128 persons with no known exposure and for 51 exposed persons. For persons with no known exposure, adipose TCDD levels ranged from nondetectable to 20.2 ppt with 95% of the levels at 16.6 ppt or less. For the 51 exposed persons, adipose tissue TCDD levels ranged from 3.7–750 ppt.
