Chemicals linked to endocrine disorder in older pet cats

September 19, 2018

New research suggests that there may be a link between higher levels of per- and polyfluoroalkyl substances (PFAS) in the environment and higher levels of hyperthyroidism in pet cats as they age. The findings are published in Environmental Toxicology and Chemistry.

PFAS are a family of more than 3,000 structures of highly fluorinated chemicals used in industrial processes and consumer products, such as protective coatings for carpets, furniture and apparel, paper coatings, insecticide formulations, and other items.

The study involved analyses of blood samples from older cats in Northern California. Investigators examined the animals' exposures to PFAS and compared PFAS levels between cats with and without hyperthyroidism, a very common endocrine disorder in senior cats. ?

"Our lab has been investigating PFAS for years. Cats can be good sentinels to examine body burdens of emerging pollutants, including PFAS," said lead author Dr. Miaomiao Wang, of the California Environmental Protection Agency. "The current study is only preliminary, however, and larger scale studies might be helpful to confirm our findings."

About Journal

Environmental Toxicology and Chemistry is interdisciplinary in scope and integrates the fields of environmental toxicology; environmental, analytical, and molecular chemistry; ecology; physiology; biochemistry; microbiology; genetics; genomics; environmental engineering; chemical, environmental, and biological modeling; epidemiology; and earth sciences. ET&C seeks to publish papers describing original experimental or theoretical work that significantly advances understanding in the area of environmental toxicology, environmental chemistry and hazard/risk assessment. Emphasis is given to papers that enhance capabilities for the prediction, measurement, and assessment of the fate and effects of chemicals in the environment, rather than simply providing additional data. The scientific impact of papers is judged in terms of the breadth and depth of the findings and the expected influence on existing or future scientific practice. Methodological papers must make clear not only how the work differs from existing practice, but the significance of these differences to the field. Site-based research or monitoring must have regional or global implications beyond the particular site, such as evaluating processes, mechanisms, or theory under a natural environmental setting.
