Revealing environmental exposure to liquid crystal monomers from digital displays
Liquid crystal monomers (LCMs) are synthetic organic chemicals used in manufacturing liquid crystal displays (LCDs) present in numerous digital electronic devices. As the use of digital electronics, such as computers and smartphones, becomes increasi.....»»
Effective policies needed to curb hormone-disrupting chemicals: Study
Without smart policymaking, banning harmful chemicals like bisphenols and phthalates—common ingredients in plastics manufacturing—can result in a game of regulatory whack-a-mole where chemicals of similar toxicity or that have not been rigorously.....»»
California state senator introduces legislation targeting industrial chemicals flowing into Tijuana River
State Sen. Steve Padilla has announced two pieces of legislation he says will address the worsening pollution of the Tijuana River......»»
Mapping chemical footprints in European streams

Caveat emptor: 90% of tattoo inks have unlabeled or mislabeled ingredients
Findings could help inform and shape emerging US policy on regulating tattoo inks. Enlarge / New study finds that the chemicals listed on tattoo ink labels often don't match what's actually in the bottle. (credit: ohsarahrose/CC.....»»
Cosmic dust could have helped get life going on Earth
Life on our planet appeared early in Earth's history. Surprisingly early, since in its early youth our planet didn't have much of the chemical ingredients necessary for life to evolve. Since prebiotic chemicals such as sugars and amino acids are know.....»»
Scientists deliver portable total chemical analysis without pumps and tubes
Researchers from Tokyo Metropolitan University have engineered a new micro total analysis system that quantifies a target chemical in a microfluidic chip without pumps, tubes, and expensive detectors. The compound reacts with other chemicals to produ.....»»
It"s not just toxic chemicals: Radioactive waste was also dumped off Los Angeles coast, scientists conclude
For decades, a graveyard of corroding barrels has littered the seafloor just off the coast of Los Angeles. It was out of sight, out of mind—a not-so-secret secret that haunted the marine environment until a team of researchers came across them with.....»»
