Threatened Killer Whales Exposed to PAHs from Petrogenic and Pyrogenic Sources: Pregnant Whales Transfer Pollutants to Fetuses, Emphasizing Need for Improved Management and Regulation of Oil Spills and PAH Pollution in Their Habitats: Study in British Columbia

https://pubmed.ncbi.nlm.nih.gov/38114485

This study found that threatened killer whales in British Columbia are exposed to PAHs from both petrogenic (oil-related) and pyrogenic (fire-related) sources, and pregnant whales can transfer these pollutants to their fetuses, highlighting the need for improved management and regulation of oil spills and other PAH pollution in their habitats.
