Scoping the uncertainty in screening for bioaccumulation potential of substances for which octanol is not a reasonable simple surrogate for partitioning; including an assessment of alternative surrogates and toxicokinetic methods

Suppliers to review all information on the Request for Quotation (RFQ) and to complete and return the following information: completed Commercial Response template, separate response submission for each technical question (in accordance with the response instructions found in "Evaluation Methodology" section of RFQ), completed Mandatory Requirements (Annex 1 of RFQ), completed Acceptance of Terms and Conditions (Annex 2 of RFQ).

Additional information: "Evidence of bioaccumulation in field monitoring and regulatory testing indicates that existing guidelines to screen for bioaccumulation may not capture all organic chemicals that bioaccumulate. This project aims to: 1. identify new methods that could be used to screen for bioaccumulation in a more holistic and comprehensive manner; and 2. evaluate whether these are fit for purpose as regulatory tools in support of UK REACH chemical registration requirements."
