  • 4. Transport and Fate of Arsenic in Marine Sediments• Objectives: – Determine the partitioning of arsenic between deep sea sediments and seawater to evaluate the mobility of As (III) derived from lewisite – Determine potential for bioaccumulation of arsenic in benthic macroinvertebrates exposed to contaminated sediments – Evaluate the ability of test organisms to excrete accumulated arsenic when Nerve agent (GB, VX, GA), returned to clean sediments Mustard, 52% 1%• University of Hawaii is Arsenic, AsCl3, Cl2S2, 2% Lewisite, 41% conducting bench top Phosgene, 0% Unspecified experiments under Blood agents (CK, AC), 1% agent, 3% contract to the Army | 4
