ABSTRACT
Fish bioconcentration tests are time consuming, expensive, and use many animals. Alternative methods that replace, reduce or refine the use of fish for BCF testing would therefore be of value. Test guidelines generally require that bioconcentration factors (BCFs) are determined at two exposure concentrations. However, recent revisions to the OECD Test Guideline for BCF testing (TG 305) provide the option to use only one exposure concentration, when justification is provided, although two concentrations may still be required for some regulatory purposes. Analysis of 55 studies on plant protection products demonstrates that BCF values do not significantly differ between the two exposure concentrations. This analysis therefore provides evidence to support the revision of OECD TG 305, and in particular provides justification for using the one test concentration approach for plant protection product active substances.
