SDS of cas: 140-66-9《Chemical Characterization of Recycled Consumer Products Using Suspect Screening Analysis》 was published in 2021. The authors were Lowe, Charles N.;Phillips, Katherine A.;Favela, Kristin A.;Yau, Alice Y.;Wambaugh, John F.;Sobus, Jon R.;Williams, Antony J.;Pfirrman, Ashley J.;Isaacs, Kristin K., and the article was included in《Environmental Science & Technology》. The author mentioned the following in the article:
Recycled materials are found in many consumer products as part of a circular economy; however, the chem. content of recycled products is generally uncharacterized. A suspect screening anal. using two-dimensional gas chromatog. time-of-flight mass spectrometry (GC x GC-TOFMS) was applied to 210 products (154 recycled, 56 virgin) across seven categories. Chems. in products were tentatively identified using a standard spectral library or confirmed using chem. standards A total of 918 probable chem. structures identified (112 of which were confirmed) in recycled materials vs. 587 (110 confirmed) in virgin materials. Identified chems. were characterized in terms of their functional use and structural class. Recycled paper products and construction materials contained greater numbers of chems. than virgin products; 733 identified chems. had greater occurrence in recycled compared to virgin materials. Products made from recycled materials contained greater numbers of fragrances, flame retardants, solvents, biocides, and dyes. The results were clustered to identify groups of chems. potentially associated with unique chem. sources, and identified chems. were prioritized for further study using high-throughput hazard and exposure information. While occurrence is not necessarily indicative of risk, these results can be used to inform the expansion of existing models or identify exposure pathways currently neglected in exposure assessments. And 4-tert-Octylphenol (cas: 140-66-9) was used in the research process.
