Assessing the Fate of Benzophenone-Type UV Filters and Transformation Products during Soil Aquifer Treatment: The Biofilm Compartment as Bioaccumulator and Biodegrader in Porous Media.

Overall, UVF concentrations in the sampling points ( Figure 3 a) did not exhibit a clear trend, which reflects: (1) the inherent variability of UVF concentration in the STE ( Table S5 ), especially at the O-piezometer (this noise is dampened at the downstream observation points due to sorption and dispersion); (2) the complexity of the BP-3 transformation pathway, compromising back and forward reactions conditioned to the redox potential ( Figure S2 ); and (3) the low concentrations, close to the method limit of quantification, especially for TPs.
