Field Name Description
% Effect   The magnitude of the effect (e.g., % mortality; change in weight; change in length; percent hatch; etc.). 
Analyte   The chemical substance used to create the exposure.  
CAS   CAS registry number is a unique numerical identifier assigned by Chemical Abstract Service (CAS) to a chemical substance.  
COLL  Where the animal was obtained: C (cultured-reared in laboratory); W (collected from wild); N/I (No Information); N/R (Not Reported). 
Comments  Commonly supports the effects data. 
Common name  Common name of the test animal. 
Control   The control response for the observed effect (e.g., survival, growth, reproduction; etc.). 
Dose  The frequency with which the contaminant was applied during the test. 
Duration   The duration of the exposure period: hr (hours); d (days) wk (weeks), mo (months), yr (years). 
Effect   The type of toxicological effect observed in the test animal (e.g., survival, growth, reproduction). 
ERED ID  Unique identification number autogenerated by database. 
ExpConc  The exposure concentration and units. 
Fraction   The test animal tissue used to determine tissue residue (e.g., whole body, soft tissue, liver, etc.). 
Genus Species   Scientific name of the test animal. 
Media  Type of water used to test animal: FW (freshwater); SW (saltwater) 
Mix   Whether the analyte was tested as part of a mixture of analytes or individually: yes (part of mixture), no (single), or N/I (No information). 
Risk   Summary of the risk (e.g., ED, NOED, LOED) an analyte might pose to the test animal. Previously, many risk numbers were assigned to results. Going forward ERED will not report a risk number unless it is reported in the study.  
Route   The route by which the analyte was intended to enter the body: aquatic; diet; injection. 
Signif   Whether the effect was significantly different, usually compared to the control for laboratory studies: Yes (significant); No (not significant). 
Source  Reference from which data was obtained. 
Spiked  Whether the analyte was spiked into the route (aquatic, diet, sediment, injection): yes (analyte spiked), no (analyte not spiked) 
ST  Study type: L (Lab); F (Field); L/F (Lab/Field); Meso (Mesocosm); Micro (Microcosm); N/I (No Information). 
Stage   Life stage of the test animal (e.g., egg, larval, juvenile, adult). 
Tissue ww (mg/kg)   Tissue residue of analyte in the test animal tissue (mg/kg wet weight). 
Trend   The trend of the effect, usually compared to the control for laboratory studies: INC (increase); DEC (decrease), NEF (No effect).
