ERDC Environmental Laboratory (EL) expertise supports the Corps of Engineers and other agencies in assessing bioaccumulation and trophic transfer of contaminants for dredged material evaluations, risk assessments, development of remediation goals, and assessment of remediation success. Bioaccumulation is the net accumulation of a chemical in an organism from various sources in its surrounding environment. Trophic transfer refers to dietary bioaccumulation and is considered the major mechanism for contaminant accumulation in organisms higher up in the food web. ERDC-EL assesses bioaccumulation and trophic transfer of contaminants through direct sampling from contaminated field sites or through laboratory-based studies. ERDC-EL can also predict trophic transfer via mathematical modeling. |
