Report published on further development of screening tests for the evaluation of potential PBT substances

Different ready biodegradability tests (OECD 301 series and OECD 310) are currently used for evaluating if a substance is readily biodegradable and for identifying potentially persistent substances. Although the methods differ considerably, the test results are considered equivalent. In persistency assessments under REACH, enhanced ready biodegradability tests with an extended test duration (up to 60 […]

New publication: Compartment‐specific screening tools for persistence – potential role and application in the regulatory context

The persistence assessment under REACH relies on compartment‐specific degradation half‐lives derived from laboratory simulation studies with surface water, aquatic sediment or soil. Although these data are given priority, they are not available for most of the compounds. Therefore, according to the integrated assessment and testing strategy for persistence assessment, results from ready biodegradability tests are […]

Further development of simple test systems for the evaluation of potential PBT substances: How to bridge the gap between screening tests and complex studies?

The first aim of the project was to assess whether the existing OECD test guidelines for ready biodegradability of chemicals (OECD test guidelines 301 A–D and 310) can be harmonized. The gained insights were discussed at an international expert workshop in April 2019. Laboratory experiments were performed for five test substances to verify the impact […]
