The PFAS-Chart allows us to visualize trends inside fresh data towards PFAS’s pastime/property dating to be able to figure out undetectable structure-poisoning relationship that’ll n’t have started easily viewed when the same data is exhibited inside the tabular mode

5 and 6, respectively. The subclasses in the class of FASA-based PFAA precursors follows the structural pattern as C_nF_{2n+step 1}-SO₂N(C_mH_2m)-R 1 . 5). First, the perfluoroalkyl chain length increases mainly due to increase in the value of t-SNE-PCA-2. In addition, the sizes of N-alkyl group e functional group but different sizes of N-alkyl group. Furthermore, the PFASs with the same perfluoroalkyl chain but different functional groups are also separated. The n:2 fluorotelomer subclasses in the class of FASA-based PFAA precursors follows the structural pattern as C_nF_{2n+step one}-C₂H_cuatro-R 1 . The distribution pattern of the n:2 fluorotelomers are similar to the FASA-based precursors—the perfluoroalkyl chain length increases mainly along t-SNE-PCA-2 (except fluorotelomer phosphates) while the functional groups separate subclasses. Similar patterns in the perfluoroalkyl chain lengths, size of alkyl group(s), and the separation based on functional groups are also observed in the subclasses of other classes, as is shown in figshare File 1.
