Surface Water Toxicity - Summary Results
This resource is a subset of records from the CEDEN Toxicity database, filtered to contain only summary records. Summary records are entries in the database that summarize the results from multiple replicate toxicity tests of the same sample water. The replicate results are available in the Surface Water Toxicity - Replicate Results resource.
The date appended to the end of the filename (YYYY-MM-DD) indicates when the data were last refreshed from the CEDEN database.

OData query
Use the resource's OData URL and its field names for paging, selecting columns, or filtering rows.
ODATA_RESOURCE_URL?$top=5
ODATA_RESOURCE_URL?$skip=5&$top=5
ODATA_RESOURCE_URL?$select=FIELD_NAME&$filter=FIELD_NAME eq 'VALUE'Replace ODATA_RESOURCE_URL, FIELD_NAME, and VALUE with the details for the selected resource. See the OData query options guide (opens in a new tab) for more examples.
