Methods/Indicators for Determining When Metals Are the Cause of Biological Impairments of Rivers and Streams: Species Sensitivity Distributions and Chronic Exposure-Response Relationships from Laboratory Data
This final report details the methodology for statistical analysis of data on metals toxicity to aquatic organisms and application of analysis results to Stressor Identification. There are 12 appendices which accompany the report to provide source data along with graphical and tabular output.
Due to the size and complexity of these appendices - they are not coded for accessibility. If you need help with these attachments, please phone 513-569-7598 or email the NCEA Technical Information Unit (TIU) of Cincinnati for assistance.
This final report describes an analysis of data on the toxicity of metals to aquatic organisms in laboratory toxicity tests and how to apply this information in a Stressor Identification Assessment. Results are provided in the form of species sensitivity distributions (SSDs) and concentration-response relationships for individual aquatic species.
This report provides information on the effects of metals on laboratory animals which may be used in the strength-of-evidence step of the Stressor Identification (SI) Process to help determine whether metals contribute to biological impairments.
