Outline of Final Research Achievements

Contamination status, exposure pathways, and risk assessment of persistent organic pollutants (POPs) such as polybrominated diphenyl ethers (PBDEs), personal care products (PCPs), and rare metals were studied for companion animals, pet dogs and cats, which could be useful “sentinel animals” to evaluate indoor exposure of the above chemicals for infants. The study results revealed that companion animals are exposed to POPs, PCPs, and trace elements via not only their foods but also indoor dust, and indicated that PBDE exposure might adversely affect thyroid hormone homeostasis in pet cats. The present study provided valuable scientific findings to assess the indoor environment-derived risks for companion animals, and infants investigating in the Japan Environment and Children’s Study (JECS).
