For each chemical (first column on the left), a series of endpoint information
is presented in the next four columns. These fields are the:
Tox Exposure: the value(s) indicating the degree of exposure
and units of exposure
Endpoint Type: the general type of toxicological endpoint
Endpoint Description: specific description of the endpoint
value and how it was evaluated or measured
Endpoint Value: the numerical or textual value associated
with the endpoint type. Accumulation data are reported as tissue residue
concentrations. Toxicological effects data may be reported in a variety of
formats. If effects are significant (as indicted by citation authors), the
effects values are expressed relative to control values (e.g., % change from
control, decrease @ dose value). If effects are not significant, the endpoint
value is listed as No effect. Benchmark dose values are entered as a
dose. The term, "see citation," indicates that endpoint values are presented in a
figure. "Review" indicates the citation is a secondary source that contains a
collection of endpoint values.
The lettered Note contains the remaining description, remarks and additional
information for the dataset. Some of these fields may be blank for a particular
dataset and will not appear in the Note. The order of information in the Note
are as follows:
- Life Cycle Stage: stage of the animal at the time data were
collected
- Location, County: general study location displayed as California
county
- Location, Lab: general study location displayed as laboratory
- Location, State/Country: general study location displayed as a state or
country
- Sex: sex of the animals for which data were collected
- Species Name (Species-California): genus and species name
- Chemical Name (TOX Chemical): Chemical Abstracts Service Registry Number
- Dose-Response Data Format (Tox Dose-Response Data Format): format of dose-response data in citation
- Sample Size (N): the number of animals from which data were collected
- Age-Specific (Age): the age of the animal at the time data were collected
- Condition (Condition): modifying factors that may influence the exposure factor such as activity, breeding or feeding status
- Season/Month: time of year in which data were collected;
- Location-Specific: for field studies, the location where the data were
collected
- Exposure Technique (Tox Exp Tech): method or route(s) by which study animals were exposed
- Exposure Duration (Tox Exp Dur): amount of time over which study animals were exposed to chemicals
- Study Duration (Tox Study Dur): inclusive of exposure duration and post-exposure time over which animals were observed
- Statistical Significance (Tox Stat Sig): denotes whether change in endpoint was statistically different from control
- Remarks general comments about the dataset.
