Figure Lengend Snippet: Time series of parent TBBPA DME mass in (a) solutions, (b) roots, (c) stems and (d) leaves of pumpkin seedlings in TBBPA DME exposure reactors and its controls. The UCs stands for “unplanted controls”. The dashed lines in (a), (b) (c) and (d) were nonlinear regressions (a. Y = 3583*exp(−X/1.1) + 894 R2 = 0.960; b. Y = 2570*(1 −exp(−1.1X)) R2 =0.992; c. Y = 0.093X3 −2.7X2 + 22X + 0.0037 R2 = 0.899; d. Y = 5.0*(1 −exp(−0.18X)) R2=0.849. X stands for the time (d) and Y stands for the mass (ng), R2 is the determinant coefficient).

Article Snippet: Chemicals and regents TBBPA DME (50 μg mL −1 in nonane, ≥ 98%), surrogate standards of 13 C 12 -TBBPA (50 μg mL −1 in methanol, 99%) and 13 C 12 -TBBPA DME (100 μg mL −1 in toluene, 99%) were purchased from Cambridge Isotope Laboratories, Inc. (Andover, MA, USA).

Figure Lengend Snippet: Time series of parent TBBPA mass in (a) solutions, (b) roots and (c) stems of pumpkin seedlings in TBBPA exposure reactors and its controls (no TBBPA was found in leaves). The UCs stands for “unplanted controls”. The dashed lines were nonlinear regressions (a. Y = 3597*exp(−X/0.72) + 900 R2 = 0.975; b. Y = 2508*(1 −exp(−0.95X)) R2 = 0.967; c. Y = 0.99*(1 −exp(−1.8X)) R2 =0.854. X stands for the time (d) and Y stands for the mass (ng), R2 is the determinant coefficient).

Figure Lengend Snippet: Variations of the total recoveries (mass balance) of parent TBBPA DME and parent TBBPA in separate hydroponic exposure systems over time. The dashed lines were nonlinear regressions (For TBBPA DME: Y = 24*exp(−X/2.3) + 76 R2 = 0.652; for TBBPA: Y = 11*exp(−X/0.073) + 207*exp(−X/102) −118 R2 = 0.865. X stands for the time (d) and Y stands for the mass (ng), R2 is the determinant coefficient).

Figure Lengend Snippet: Mass variations of metabolites TBBPA and TBBPA MME in (a) roots and (b) hydroponic solutions in the exposure experiments of TBBPA DME over time. The colored dashed lines were nonlinear regressions (For TBBPA: a. Y = 0.13*exp(X/3.0) − 0.13 R2 = 0.864; b. Y = 0.0070*exp(−X/2) − 0.0068 R2 =0.800. For TBBPA MME: a.
