Bioaccumulation

Bioaccumulation describes the enrichment of chemicals in organisms. The uptake of substances occurs either via food (biomagnification) or directly from the abiotic environment (bioconcentration). Experimentally determined bioaccumulation factors are an important element in the risk assessment of chemical substances. The basis for bioconcentration studies with fish is the OECD Guideline 305 (flow-through fish test).

Especially for highly lipophilic chemicals (log P > 5) bioconcentration studies are often difficult to perform. Lipophilic substances are poorly water soluble, which makes the adjustment of stable test concentrations difficult and, under certain conditions, may cause inexact measurements of the test substance in the medium. For poorly soluble chemicals an alternative test design for the performance of bioaccumulation studies based on feeding experiments is available in the scope of the revised OECD guideline 305. The aim of these studies is the determination of the biomagnification factor (BMF).
