A study finds that 87 out of 362 liquid crystal monomers (LCMs) currently used in liquid crystal displays (LCDs) were potentially persistent and bioaccumulative based on their resistance to degradation and environmental mobility, that exposure of embryonic chicken cells to LCM mixtures from 6 LCD devices altered gene expression in a manner similar to other persistent organic pollutants, and that several LCMs could be detected in indoor dust samples.
