Story summary

A study by Yuhe He, an associate professor at City University of Hong Kong, found toxic pollutants in endangered dolphins and porpoises, prompting calls for stricter electronics regulations.
The research analyzed 63 samples from 16 Chinese white dolphins and 26 Indo-Pacific finless porpoises that washed ashore between 2007 and 2021.
Results indicated that 88% of samples contained detectable liquid crystal monomers (LCMs), primarily in the blubber, muscles, and brains, which can breach the blood-brain barrier and pose risks to both dolphins and humans.
