ENDOCRINE TEST VALIDATION
While EPA is concentrating on validating tests for endocrine effects in humans, the
Biological Resources Division (BRD) of the United States Geological Survey is trying to validate tests for
endocrine effects in wildlife. One of these tests is to determine atrazine’s endocrine effects on frogs.
BRD’s current schedule calls for completion of this validation process on July 30, 2004.
CRE’s Position on Test Validation
EPA’s FIFRA/FQPA environmental risk assessment for atrazine states that atrazine causes
endocrine effects in frogs and other wildlife. These statements are not based on any validated tests
because there currently are no such validated tests. CRE, the Triazine Network, and the Kansas Corn
Growers Association filed a Request for Correction of EPA’s statements under the Data Quality Act.
This Petition argues that EPA’s endocrine effects statements violate the Data Quality Act’s standards
because there are no validated tests to determine whether atrazine causes endocrine effects in
