Subform VII: Scientific Study

1. Study Reference

Title Short-Term Reproduction Assay with Fathead Minnow

Date 28-FEB-12

2. a) Is an extension needed to translate the document?

No

3. Type of incident identified in the study

New health or environmental hazard

4. Describe the incident identified in the study (e.g. study demonstrates an increased risk to non-Hodgkin's Lymphoma after exposure to pesticide X)

Submitted to EPA under the EDSP data call-in (EDSP-059201, phosmet). Results may be reportable. There was no indication of endocrine effects per se in the attached study. The attached new data do not represent any practical likelihood of adverse effects occurring to species in the wild. Flow-through experimental test conditions were employed to artificially maintain constant concentrations of test substance over the testing intervals. Given the very rapid hydrolysis of phosmet (half life approximately 9 hours at neutral pH), there is no possibility of environmental exposure occurring in the manner employed in the screening study.

5. a) Was the study discontinued before completion?

No

5. b) Provide the reason for discontinuation

For Registrant use only
