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 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 has been designed to obtain the information necessary to confirm or to further characterise the potential neurotoxicity of chemicals in adult animals. This Test Guideline is designed for use with the rat. It specifically addresses the daily oral administration, by gavage, (in...

This Test Guideline includes two methods: a paper contact toxicity test and an artificial soil test. The recommended specie is Eisenia foetida (Michaelsen). The initial screening test (filter paper contact test) involves exposing earthworms to test substances on moist filter paper in order to...
