Show Ecological Risk Assessment Northern Oquirrh rv,ountains 2. Analysis The Analysis section of the EcoRA presents the available information for characterizing CoC exposure and potential ecological effects to fauna and flora in the Core Project Area. It integrates information presented in the Screening Level EcoRA with new data collected in 1995 to address specific questions outlined in the Work Plan and with additional published information. 2.1 Approach for Data Acquisition acquired from several sources, including published literature, for where KUC, and, necessary, from field work conducted during 1994 and 1995. reports Data for the EcoRA was 2.1.1 Acquisition of Existing Information The Screening Level EcoRA in 1994 outlined the sources of existing information on CoC concentrations and distributions in the northern Oquirrhs. Information on the toxicity of the compiled from a review of original research reports. A comprehensive literature search was conducted using electronic databases available at Oregon State University, Portland State University, and Reed College. Each article was reviewed to ascertain the scientific quality of the study. A study was not used if there were The no control or reference groups or if it was a case report on one or two animals. the were to of statistical tests evaluated if the conclusions from was report appropriateness CoC to terrestrial wildlife was be used. acquired from literature reports of field studies conducted at other sites that related ecological effects and CoC concentrations in biotic tissues to CoC concentrations in food or other environmental sources (e.g., soil or water). This information was used for comparing site-specific trophic transfer factors with those calculated from Additional information was data reported in the literature from other sites. 2.1.2 Approach to 1995 Data Collection The Work Plan developed for the EcoRA described the scope of the 1995 data collection, including the project design; the methods for sample collection, small mammal necropsy of small mammals, and tissue histology; and the analytical procedures for measuring CoC concentrations. The Work Plan also included details on all Quality Assurance (QA) and Quality Control (QC) measures to be followed for each phase of data collection. The objectives for this data collection were based on the findings of the 1994 Screening Level EcoRA in order to address the areas of greatest potential risk to plants and wildlife from the cec. ecological planning and toxicology, inc. 19 |
