The spill initially was thought to be all acetone — a solvent used in many nail polish removers that can irritate the nose, throat, eye and skin at moderate to high levels of exposure. The campus did not identify the liquid until the next day, when staff determined that the broken bottles contained not only acetone but another more harmful solvent called dimethylformamide, a known liver toxin that can cause abdominal pain, dizziness, skin problems and nausea.
