Description of key information

Reports in the literature (Halldin et al., 2001; Berg et al., 2001) indicate TBBPA orally or intravenously administered to laying quail was rapidly eliminated via bile into feces. Transfer to egg yolks was low. In quail eggs, embryonic uptake of TBBPA was low (< 1% of the radiolabel) after yolk injection on day 3 of incubation. Thus, TBBPA was readily excreted by the laying female as well as by the growing embryo, and consequently, the risk for embryonic exposure following dietary intake in laying birds is expected to be low.
Given the rapid elimination of TBBPA by rats, humans, fish and invertebrates, and high no effect levels, dietary exposure to TBBPA in birds is highly unlikely to result in doses large enough to produce toxicologically relevant effects. Consequently, data concerning the dietary toxicity of TBBPA to birds is considered unwarranted and not scientifically justified.
