This Test Guideline describes the HPLC method, which permits to determine the partition coefficient (n-octanol/water) (Pow).Reverse phase HPLC is performed on analytical columns packed with a solid phase containing long hydrocarbon chains chemically bound onto silica. The chemicals are retained...

This Test Guideline describes a laboratory test method to assess abiotic hydrolytic transformations of chemicals in aquatic systems at pH values normally found in the environment (pH 4 – 9). This Guideline is designed as a tiered approach; each tier is triggered by the results of the previous...

This Test Guideline describes a laboratory test method designed to investigate long term potential effects of a single exposure of agrochemicals/non agrochemicals on carbon transformation activity of soil microorganisms. A minimum of two test concentrations are recommended for agrochemicals...

This Test Guideline describes a method to assess bioaccumulation of sediment-associated chemicals in endobenthic oligochaetes worms. It applies to stable, neutral organic chemicals having log Kow values between 3.0 and 6.0, superlipophilic substances that show a log Kow of more than 6.0, or...
