Biomonitoring for the Georgia Coast:
-- Assessing the Impacts of Contaminants on Aquatic Resources
-- Persistent Contaminants, DNA Damage and Endocrine Disfunction in Finfish


PIs: Keith Maruya (formerly: Skidaway Institute of Oceanography, Savannah, GA, USA)

Support: GA DNR Coastal Zone Management (through Coastal Incentive Grants)

Timeframe: 1998 - ongoing

Project Overview:
A draft Biomonitoring Plan was created to provide coastal resource managers with a science-based tool for addressing the unknown effects of chemical contaminants on coastal resources. This document was based on peer-reviewed literature and a limited amount of field testing of promising techniques.  Two promising "biomarkers" of chemical exposure/insult are slated for further investigation -- DNA damage and blood hormone (im)balance.  A 3-year study has been outlined where two species of finfish (mummichogs and seatrout) are collected from several coastal sites impacted to varying degrees and tissues analyzed for persistent metal and organic contaminants in addition to the aforementioned biomarkers. Relationships among the measurements will be addressed using ANOVA and multivariate regressions.
