Potentially applicable publications were identified through comprehensive searches of the open literature (see Attachment 3-1 for plants and soil invertebrates, and Attachment 4-2 for mammals and birds). Literature citations and full articles were skimmed for potential applicability and acceptability to the Eco-SSL effort (see Attachment 3-1 and Attachment 3-2 for plants and soil invertebrates, and Attachment 4-3 for mammals and birds).

Publications identified as "Acceptable" met all minimum criteria and received a sufficient score during the data evaluation process, but may not have been used to derive the final Eco-SSL due to other data selection requirements (see Attachment 3-2 for plants and soil invertebrates and Attachment 4-3 for mammals and birds). Publications identified as "Not Acceptable" either did not meet all the acceptance criteria, fell into exclusion categories, or did not receive a sufficient score in the evaluation process. See Literature Rejection Category Keywords for definition of codes describing the basis for rejecting a paper.

When will the Eco-SSL Chemical Specific documents be finalized?

The Eco-SSL Chemical Specific documents are interim in case this publication results in the submission of a significant number of new studies that were missed in the original literature searches. If this happens, EPA would review the tests and recalculate the final Eco-SSL.

When will the remaining Interim Eco-SSLs and Documentation be completed?

EPA is currently working on the 'pending' documents, but does not have a specific schedule for future release of documents.
