Story summary

Toxic liquid crystal monomers (LCMs) from electronic waste were found in endangered dolphins and porpoises in the South China Sea, per Environmental Science & Technology.
The chemicals can cross the blood-brain barrier, raising concerns about potential human health risks from seafood.
Researchers analyzed tissue samples over 14 years, linking LCM levels to their use in electronics.
With about 62 million tonnes of e-waste generated annually, they urge extending electronics lifespans and tightening regulations to prevent a future public health crisis.
