Abstract
An advanced analytical chemistry laboratory experiment is described that involves environmental analysis and gas chromatography–mass spectrometry. Students analyze lint from clothes dryers for traces of flame retardant chemicals, polybrominated diphenylethers (PBDEs), compounds receiving much attention recently. In a typical experiment, ng/g levels of three PBDE congeners (#47, #99, and #100) were found in the dryer lint through use of several mass spectral modes: negative chemical ionization–selected ion monitoring (MS–NCI–SIM) and tandem mass spectrometry with electron ionization and selected reaction monitoring (MS–EI–SRM). Students gain experience in Soxhlet extraction, mass spectrometry, and isotope dilution analysis as they explore their own local environments.

 Caution! 
Experiments, laboratory exercises, lecture demonstrations, and other descriptions of the use of chemicals, apparatus, instruments, computers, and computer interfaces are presented in the Journal of Chemical Education as illustrative of new or improved ideas or concepts in chemistry instruction and are directed at qualified teachers. Although every effort is made to assure and encourage safe practices and safe use of chemicals, the Journal of Chemical Education cannot assume responsibility for uses made of its published materials. Many chemicals are hazardous. Precautions for the safe use of hazardous chemicals and directions for their proper disposal are described in the Material Safety Data Sheets and on the labels. We strongly urge all those planning to use materials from our pages to make choices and to develop procedures for laboratory and classroom safety in accordance with local needs and situations.
