Case reports demonstrating neurotoxic, reproductive, development and other health effects in workers who use or make 1-BP indicate that the brominated solvent may represent an unrecognized occupational health risk. In this week's issue of the Centers for Disease Control and Prevention's Morbidity and Mortality Weekly Report, the National Institute for Occupational Safety and Health (NIOSH) presents two independent cases of 1-BP exposed workers diagnosed with the clinical manifestations of neurotoxicity. Read More >
