Bioaccumulation and bioconcentration studies are often integral to the evaluation of hazards to human and aquatic life and useful for compliance with NPDES or other regulatory requirements. GLEC has the resources to conduct laboratory and on-site field bioaccumulation/ bioconcentration studies that measure the effects of pollutants on the survival, growth, and behavior of aquatic species. Mobile laboratories are used to expose fish and/or shellfish to site waters. Bioconcentration studies of fish, shellfish, and other invertebrates for specific chemicals are typically conducted in our Columbus and Traverse City toxicology laboratories, including provision of custom laboratories designed to measure specific bioaccumulative effects. Development of site-specific bioaccumulation factors (BAFs) utilize GLEC’s special expertise in the water quality and trophic level considerations affecting BAF values. GLEC’s environmental chemistry capabilities often complement bioaccumulation/ bioconcentration studies, including biouptake studies of fish tissue from site waters.
Along with our extensive field and laboratory capabilities, GLEC plays a key role in the development, evaluation, and validation of national BAF methods, models, and standards. Our broad expertise and involvement assures that clients in both the regulated and regulatory communities benefit from the highest quality deliverables. All GLEC field and lab operations followed prescribed EPA, ASTM, or other specified methods/ protocols and comply with proven GLEC quality plans and procedures.
GLEC operates one of only a few U.S. laboratories accredited for whole sediment toxicity testing. GLEC also maintains NELAP accreditation for chlorophyll and nutrient chemistry testing.
