Summary:
- This article discusses the use of chromatography techniques to detect the presence of per- and polyfluoroalkyl substances (PFAS) in the blubber of killer whales.
- PFAS are a group of synthetic chemicals that are persistent in the environment and can accumulate in the bodies of living organisms, including marine mammals like killer whales.
- The study found that various types of PFAS were present in the blubber samples, indicating that these chemicals are being transferred through the food chain and accumulating in the tissues of these apex predators.
