Long‐Term Monitoring of an In Situ Activated Carbon Treatment to Reduce Polychlorinated Biphenyl Availability in an Active Harbor

Abstract

Activated carbon-based amendments have been demonstrated as a means of sequestering sediment-associated organic compounds such as polychlorinated biphenyls (PCBs). In a 2012 effort, an activated carbon amendment was placed at a 0.

Quantitative thermodynamic exposure assessment of PCBs available to sandworms (Alitta virens) in activated carbon remediated sediment during ongoing sediment deposition

“…Of the remedial approaches available, mixing or amending contaminated sediments with activated carbon (AC) is increasingly used for sorbing hydrophobic organic contaminants (HOCs) and thereby lowering their freely dissolved concentrations (C free ) and, consequently, their bioavailability in the contaminated sediment. [1][2][3][4][5] Meanwhile, ongoing inux of fresh sediment and associated HOCs is a common occurrence at contaminated sediment sites, which are oen located in protected net depositional areas. 6 Ongoing input sources, both dissolved and particulate associated, have challenged remediation and monitoring efforts at many contaminated sediment sites.…”
