OECD 301F Manometric Respirometry Test for Ready Biodegradability

    Introduction To OECD 301F

    The OECD 301 F test is one of the tests in the OECD 301 series to determine the ready biodegradability of a chemical, where biodegradation occurs in an aerobic environment. Known as the Manometric Respirometry Test. This test assesses oxygen uptake by microorganisms during the degradation of a test substance and the determination of true biodegradability.

    Test Procedure of OECD 301F

    Test procedure A closed bottle contains some water and the sample material, creating a small air space inside. As the sample breaks down, it uses up both the oxygen and the air space. The drop in oxygen pressure is quantified using a manometer, which serves as a measure of the biodegradation rate.

    OECD 301F Sample Preparation

    Specimen DetailsThe bottle is kept in aerobic conditions, usually at a stable temperature of 20±2°C, for a duration of 28 days. Throughout this time, the microorganisms can break down the test substance, using oxygen as part of the process.

    OECD 301F Result and Interpretation 

    At the end of this test, we can determine the Consumed Oxygen(CO) and then compare it to the calculated theoretical oxygen demand.
