Multiple lines of evidence for assessing benthic impacts
Michael Rondinelli, a scientist at OBG, recently presented a poster during the 2017 Annual Spring Meeting of the Hudson-Delaware Chapter of the Society of Environmental Toxicology and Chemistry (HDC SETAC) on April 26-27, 2017 in South Orange, New Jersey.
In Multiple Lines of Evidence for Assessing Benthic Impacts in the Lower Genesee River, Michael provides a case study of the potential impacts of sediment concentrations of metallic contaminants from photographic film manufacturing processes to the benthic invertebrate community inhabiting the Lower Genesee River in Rochester, New York.

Abstract: Benthic macroinvertebrates are excellent bioindicators of sediment and water quality conditions and respond measurably to pollution releases and other anthropogenic perturbations to aquatic systems.
The potential for adverse impacts to the benthic invertebrate community inhabiting the Lower Genesee River (Rochester, New York) from exposure to chemical parameters of interest (CPOIs) in river sediment was evaluated through multiple lines of evidence, including surficial sediment concentrations, benthic community structure and composition, benthic soft tissue concentrations, and sediment toxicity testing.
The Lower Genesee River historically received releases of CPOIs, primarily metals (notably silver), from the Eastman Business Park where photographic products were manufactured for over a century.
This work was conducted as part of a remedial investigation of the Lower Genesee River to quantify the nature and extent and evaluate environmental impacts of inorganic and organic CPOIs associated with the business park.
