Summary

Story summary

New research finds liquid crystal monomers (LCMs) from electronic waste pose neurotoxic risks to dolphins and porpoises in the South China Sea, published in Environmental Science & Technology.
The chemicals likely enter the animals through diet rather than direct water exposure.
LCMs can accumulate in various organs, including the brain.
Researchers call for regulatory action and improved disposal methods for electronic waste to protect ocean health.
