Contaminant Data and Growth and Survival Measurements From Juvenile Chinook Salmon Dietary Exposure Study 2020-02-02 to 2021-04-19 (NCEI Accession 0290149)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 04:40 AM | Dataset Last Updated: March 21, 2024 at 12:00 AM
The data included in this package were conducted as part of a Natural Resource Damage Assessment (NRDA) addressing historical pollution at the designated Superfund site. The National Oceanic and Atmospheric Administration (NOAA) evaluated contaminant-related effects from dietary exposure to environmentally relevant concentrations and mixture profiles in juvenile Chinook salmon using two endpoints: growth assessment and disease susceptibility. The dose and chemical proportions were determined from the stomach contents of Laboratory-reared juvenile Chinook salmon recently collected from contaminated waterways. Groups of fish were fed a mixture with fixed proportions of polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethanes (DDTs), and polycyclic aromatic hydrocarbons (PAHs) at five concentrations for 35 days. Data is provided in three spreadsheets in 0-data/Data/ directory and include the length , weight, otoliths, and tissue chemistry of composite samples of lab-raised juvenile Chinook salmon. The corresponding data dictionary for the headers is located in 0-data/Documentation/DataDictionary/ and describes the specific chemical, biological, instruments, etc. codes. Metadata XML files describing the sampling processing procedures are provided in the 0-data/Metadata for each respective experiment. The file 0-data/Data/readme.txt describes the data package and contents of each directory in more detail.
