From page 297...
... Risk characterization involves comparison of exposure estimates with measures of hazard; this process might result in compounding of errors. Ecological risk assessments do not track individuals over time and so do not accurately reflect population changes.

From page 298...
... Hence, a formal uncertainty analysis was performed with Monte Carlo methods and assumed probability distributions of the rate coefficients. The 95% confidence limits of predicted TCDD concentrations in water and sediment differed by a factor of 10-100.
