Sensitivity of Cytochrome P450 -1A1 Induction in Fish as a Biomarker for Distribution of TCDD and TCDF in the Willamette River, Oregon.

Sampling sites were selected based upon possible industrial pollution sources. Surface sediment at six stations in the Willamette River mainstem and Middle Fork were sampled for dioxins and furans. A control site upstream from a bleached-kraft pulp mill discharge (RK 232), a site below a municipal sewage outfall (RK 206), and a site adjacent to an industrtial waste dump contaminated with organochlorines (RK 11). Sampling and analysis included both fish and surface sediments. This study also included measurement of the specific tissue content of cytochrome P-450 1A1 as a bioindicator of contamination and assessed fish health by histopathology and clinical chemistry. Curtis et al. (1993,1991) contain provide summaries of these additional data.
