Pharmaceuticals and personal care products (PPCPs) were measured in porewater, sediment, and surface water at three sites near wastewater treatment plant (WTP) discharge along a 2 km downstream transect in a tributary shoal embayment (Alexandria, VA) of the tidal Potomac River. A benthic diffusion layer model evaluated water-only, dissolved organic carbon (DOC)-associated, and bioturbation mass transport pathways. Fluxes of 17 PPCPs nearest the WTP were all in the direction of surface water to sediment porewater (neg.) with magnitudes of -0.0016 to -7.4 ng m-2 s-1. At the next downstream site, fluxes of seven PPCPs were bidirectional (neg. and pos.) and ranged from -4.8 x 10-4 to 0.0051 ng m-2 s-1. The furthest site downstream yielded fluxes of six PPCPs that were predominantly sediment to water (pos.), ranging in magnitude from -0.0020 to 7.0 x 10-4 ng m-2 s-1. The bioturbation and water-only mass transport coefficients contributed most to fluxes for PPCPs. The DOC-associated mass transport term was negligible. The fluxes indicated sediments will continue serve as a source of PPCPs 2 km downstream from WTP discharge. This study involved multiple reactions and reactants, such as 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid (cas: 83799-24-0Formula: C32H39NO4).
2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid (cas: 83799-24-0) belongs to piperidine derivatives. Piperidine is a saturated organic heteromonocyclic parent, an azacycloalkane, a secondary amine and a member of piperidines. Some chemotherapeutic agents have piperidine moiety within their structure, foremost among them, vinblastine and raloxifene.Formula: C32H39NO4
