This study provides critical guidance for evaluating laboratory fish bioconcentration factor (BCF) studies. Applying these criteria improves the reliability of bioaccumulation assessments and predictive models for chemical safety.

Area of Science:

Environmental Chemistry
Toxicology
Ecotoxicology

Background:

Laboratory fish bioconcentration factor (BCF) data are crucial for assessing chemical bioaccumulation potential.
Current lack of standardized guidance for reviewing BCF studies hinders predictive model development and chemical management.
A multi-stakeholder workshop identified data quality issues in in vivo fish bioaccumulation studies.

Framework:

Provides practical guidance for critically reviewing experimental BCF studies.
Identifies key criteria for judging study reliability: substance/species identification, analytical measurements, absence of adverse effects, and steady-state conditions.
Emphasizes the need for transparent guidance in evaluating bioaccumulation data.

Implementation:

Guidance criteria applied to anthracene and 2,3,7,8-tetrachlorodibenzo-p-dioxin to demonstrate data quality assessment.
