“…The identified plasticizers may have originated during the manufacturing process, as they can be used as dispersion media for catalysts, dyes, fillers, and stabilizers in urethane foam feedstocks. 23 There were 13 occurrences of paired detection of a specific plasticizer in both the cover and foam layers, and higher plasticizer concentrations were associated with older mattresses (Figure 1). This suggests that, over time, the foam behaved as a sorptive reservoir for gas-phase plasticizers released from the overlying cover layer or from products found elsewhere in a residence, although greater concentrations of plasticizers may have been used during the initial manufacture of the foam in older mattresses.…”

Infants spend most of their time sleeping, where they are in intimate contact with their crib mattresses. In this study, we analyzed the cover and foam layers of 20 new and used crib mattresses for selected chemical additives. Seventeen of the 20 crib mattress covers contained at least one identifiable plasticizer, with concentrations ranging from 1 to >35% by weight. Sixty percent of the covers contained a total plasticizer content of >9% by weight. Nine of the 20 covers contained either bis(2-ethylhexyl) phthalate (DEHP) or diisononyl phthalate (DINP). In contrast, phthalate alternatives, including diisononyl 1,2-cyclohexanedicarboxylic acid (DINCH) and bis(2-ethylhexyl) isophthalate (iso-DEHP), were the most frequently identified plasticizers in crib mattresses manufactured after the U.S. Consumer Product Safety Improvement Act (CPSIA) went into effect. Flame retardants, including pentabromodiphenyl ether (pentaBDE) congeners and triphenyl phosphate (TPP), and unreacted isocyanates (NCO) were also identified in crib mattresses with polyurethane foam.
