A Hong Kong researcher is advocating for stricter electronic waste regulations after a study revealed toxic pollutants from electronics in deceased dolphins and porpoises. Researchers from City University of Hong Kong and mainland China analyzed tissue samples from marine mammals that washed up on Hong Kong beaches between 2007 and 2021. The study found liquid crystal monomers (LCMs), chemicals used in LCD screens, in 88% of the samples, with the highest concentrations in blubber, followed by muscle and brain tissue. The researcher, Yuhe He, expressed concern that LCMs can breach the blood-brain barrier, posing a potential threat to both marine life and humans. The study highlights the need for responsible electronics disposal to protect vulnerable species.
