OECD 305: Bioaccumulation in fish (aqueous and dietary exposure)
The OECD 305: Bioaccumulation in Fish Study assesses the bioaccumulation potential of a given substance in fish, and is an important component of environmental fate studies for regulatory approval. The test can assess for both aqueous and dietary exposure in either a flow-through or semi-static test regime, although aqueous and flow-through designs are preferred. After a 28-day uptake phase and subsequent depuration, test substance concentrations are assessed. Results are expressed as a bioconcentration factor (BCF) for aqueous exposure and a biomagnifications factor (BMF) for dietary exposure, though BCF is weighted more heavily when assessing the bioaccumulation potential of a substance.

About our nonclinical animal research models: We provide the utmost care for our research animals and actively pursue advances in animal welfare. As well as ensuring the highest scientific, ethical and regulatory standards, selection of appropriate animal research models for development research is critical to developing safe and effective treatments, devices and products that protect and save lives. Just as we have ethical committee oversight for human trials, we have ethical committees overseeing all aspects of our global animal care and use programs. All of our core, nonclinical facilities are accredited by AAALAC.Learn more about our commitment to replacing, reusing and refining nonclinical research models.
