described in Table S5. Further m ore, 13 co m pounds were probably for m ed through m utual interactions between detected substances or as a result of acetic acid– m ediated transfor m ations during the leaching process. The newly identified co m pounds found in the cellulose fibres are pre- su m ed to have originated fro m poly m er coatings, adhesives,
a total of 31 co m pounds were identified in the office paper sa m ple (Table 6). Eight co m pounds were identified both in cellulose fibres and in the original waste paper. Re m oved a m ounts of co m pounds ranged between 4 and 90% (Table 6). An additional ten co m pounds were newly detected exclu- sively in the cellulose fibres. Their possible for m ation is
