Abstract : A laboratory study was conducted to evaluate the stability of styrene monomer (SM) with and without the presence of an initiator on 100mg/50mg activated coconut charcoal tubes in accordance with NIOSH Method 1501, Hydrocarbons, Aromatic. The stability of SM was tested over time (0, 1, 3, 7, and 14 days), with various styrene vapor loadings (1, 2, 5, 8, and 10 ul). In addition, five ul of styrene monomer was vaporized in the presence of an initiator and deposited on charcoal tubes. These tubes were then analyzed after storage times of zero, one half, one, two, four, twenty-four and forty-eight hours. Styrene vapors, deposited on the activated carbon matrix with and without the presence of the initiator methyl ethyl ketone peroxide, were completely recovered. Polymerization, either self induced or initiated by methyl ethyl ketone peroxide, was not a factor in this recovery. p10
