The data set describes the characterization of organosilica nanoparticle thin films used to adsorb PCBs from laboratory water and a sediment collected near Anniston Alabama. Data not shown here for the porewater and sediment PCB concentrations can be found in Appendix 1 of Ingersoll et al. 2014 (http://dx.doi.org/10.3133/sir20135125) Bulk sediment chemistry was obtained from Table A1-3a.Porewater estimated from solid phase microextraction fibers was obtained from Table A1-3c. The concentration of PCB in Lumbriculus variegatus was obtained from Table A1-3e.

Data collected in a series of laboratory experiments conducted with the model freshwater snail Lymnaea stagnalis exposed to dissolved platinum (Pt), or polyvinylpyrrolidone coated platinum nanoparticles (PtNPs) of five different nominal hydrodynamic diameters in the presence (or absence) of natural organic matter (NOM) are presented in this data release. Files include 1) a data dictionary describing the variables; 2) exposure characteristics of the experimental solutions; 3) Pt concentrations in the experimental organisms; and 4) QA/QC performed during the analysis. Format of the files is comma delimited (*.csv).

This metadata record consists of 3 tables containing per-and-poly-fluoroalkyl substances (PFAS) and polychlorinated biphenyls (PCB) concentration data of wastewater and biosolid samples from wastewater treatment plants within the Patapsco and Potomac watersheds. The PCB concentration data was used to assess the occurrence and fate of PCB in wastewater treatment plants within the Patapsco watershed, from December 2021 to December 2022; The PFAS concentration data was used to assess the occurrence and fate of PFAS within the Patapsco and Potomac watersheds, from 2021-2023. The PFAS total oxidizable precursors (TOP) assay data were used to investigate PFAS fate in the wastewater treatment process of plants within the Patapsco watershed from March and September of 2022.
