Integrated Biomonitoring and Bioaccumulation of Contaminants in Biota of the cANIMIDA Study Area, Task 5. 2004-2006 Field Seasons Consolidated Report

摘要

The continuation of the Arctic Nearshore Impact Monitoring in the Development Area (cANIMIDA) Program was designed as an extension of the ANIMIDA Program. It was designed to monitor changes in the distribution and concentrations of selected chemicals in the nearshore Alaskan Beaufort Sea environment and determine if any changes observed were related to offshore oil and gas development activities. Task 5 of cANIMIDA focuses on an assessment of concentrations of petroleum hydrocarbons, including polycyclic aromatic hydrocarbons (PAH), saturated hydrocarbons (SHC), and sterane/triterpane (StTr) petroleum biomarkers, and 13 to 19 metals in soft tissues of representative species of marine bivalve mollusks, crustaceans, and fish from the offshore areas in the Alaskan Beaufort Sea near ongoing or planned oil and gas development activities. This report describes the results of chemical and biochemical monitoring of marine animals collected from the study area during the summers of 2004, 2005, and 2006. There were five objectives for Task 5 of the cANIMIDA Program: Objective 1 Improve and validate the Contractors proposed conceptual model of bioaccumulation and trophic interaction in cANIMIDA biota; Objective 2 Measure bioaccumulation in selected species by co-collection and analysis of indigenous bivalves, benthic amphipods, and fish and deployment, retrieval, and analysis of caged bivalves and SPMDs; Objective 3 - Compare bioaccumulation data to published results for the same or similar species outside the cANIMIDA area; Objective 4 - Develop a strategy for longer-term upper trophic contaminant monitoring; Objective 5 - Develop a strategy and rationale for future Boulder Patch contaminant monitoring in conjunction with Task Order 006.
