This Test Guideline describes the determining of the ultraviolet-visible (UV-VIS) absorption spectrum of a chemical compound to have some indication of the wavelengths at which the compounds may be susceptible to photochemical degradation. Degradation will depend upon the total energy absorbed...

This Test Guideline is designed to assess the toxicity of chemicals on the growth of the rooted aquatic plants (Myriophyllum spicatum) growing in water-sediment system. Shoot apices of healthy and non-flowering plant are potted in standardised, artificial sediment supplemented with additional...

The mammalian in vivo micronucleus test is used for the detection of damage induced by the test substance to the chromosomes or the mitotic apparatus of erythroblasts, by analysis of erythrocytes as sampled in bone marrow and/or peripheral blood cells of animals, usually rodents (mice or rats)....

This Test Guideline is designed to assess the toxicity of chemicals on the growth of submerged aquatic plants Myriophyllum spicatum growing in a sediment-free test system. In a modified Andrews’ medium Myriophyllum spicatum plant cultures are exposed to at least five different concentrations...

This Test Guideline is designed to be used for assessing the effects of chemicals in soil on the reproductive output (and other sub-lethal end points) of the earthworm species Eisenia fetida or Eisenia andrei. Adult worms are exposed to a range of concentrations of the test substance either...

The mammalian in vivo micronucleus test is used for the detection of damage induced by the test substance to the chromosomes or the mitotic apparatus of erythroblasts, by analysis of erythrocytes as sampled in bone marrow and/or peripheral blood cells of animals, usually rodents (mice or rats)....

This Test Guideline is designed to be used for assessing the effects of chemicals on the reproductive output of the enchytraeid worm, Enchytraeus albidus Henle 1873, in soil. Adult enchytraeid worms are exposed to a range of concentrations of the test substance mixed into an artificial soil. Ten...

The Potamopyrgus antopodarumon reproduction test is designed to assess potential effects of prolonged exposure to chemicals on reproduction and survival of parthenogenetic lineages of the freshwater mudsnail Potamopyrgus antipodarum. Adult female P. antipodarum are exposed to a concentration...

This Test Guideline is designed to assess effects of prolonged exposure to chemicals on the reproduction and survival of the hermaphrodite freshwater snail Lymnaea stagnalis (the Great Pond Snail). Reproducing adults of L. stagnalis are exposed to a concentration range of the test chemical and...

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...
