Abstract
A method for reducing the toxicity, bioaccumulation and concentration of chemicals in surface water sediments and water using a retrievable organic carbon scavenger is disclosed. The scavenger is comprised of a porous polymeric material, optionally containing an adsorbent such as activated carbon, and may exist in the form of beads, sheets, fibers, netting or other similar forms. The material is placed in contact with the sediment, toxic compounds are absorbed from the sediment, and may be retrieved for regeneration or disposal.
