"High concentrations of synthetic chemicals have been detected in Tsushima leopard cats, an endangered species found only on one island between Kyushu and South Korea, a research team said.

The pollutants are polyfluoroalkyl substances (PFAS), known for their ability to repel oil and water. They are nearly non-degradable in nature and pose significant environmental and health risks.

The Tsushima leopard cat is listed in the “Endangered Class 1A” category on the Environment Ministry’s red list and is also designated by the central government as a natural monument."
