The purpose of this test is to measure the time course of biodegradation of a test substance at low concentration in aerobic natural water and to quantify the observations in the form of kinetic rate expressions. The test is performed in batch by “pelagic test” or “suspended sediment...

This Test Guideline describes two simulations tests used in the aerobic sewage treatment. Activated Sludge Units are designed to determine the elimination and the primary and/or ultimate biodegradation of water-soluble organic compounds by aerobic micro-organisms in a continuously operated test...

This report analyses the importance of the adoption and the effective use of information and communication technologies (ICTs) for enabling digital innovation for growth and inclusiveness, and discusses the role of public policies in stimulating such adoption and use. Given the emergence of a...

This test guideline describes a test procedure to gain information on dispersion stability of manufactured nanomaterials in simulated environmental media. The main purpose of this guideline is to assess the ability of a nanomaterial to attain a colloidal dispersion and to conserve this...

This book takes stock of the past two decades of public sector modernization in OECD countries. These years have witnessed an influx of new ideas and initiatives but how have these new ideas worked in practice? This report assesses failures and successes and identifies the challenges ahead. It...
