This study relates to the analysis, via dermal application, of the health hazard of solid or liquid test substance. This method is composed of two tests: the main test and the limit test. This Test Guideline is intended for use with the adult rat, rabbit or guinea pig. At least 10 animals (5...

Metabolism in Livestock studies are used to determine the qualitative and quantitative metabolism and/or degradation of the active ingredient resulting from pesticide use in feedstuffs, direct application to livestock, or premise treatment. The studies provide an estimate of total residues in...

This Test Guideline is a laboratory test method, designed to assess the oral acute toxicity of pesticides and other chemicals, to adult worker honeybees. Adult worker honeybees are exposed to five doses in a geometric series of the test substance dispersed in sucrose solution. A minimum of three...

This Test Guideline is a screening method for the evaluation of ready biodegradability of chemical. The test substance, normally at 20 mg C/L, as the sole source of carbon and energy, is incubated (during 28 days normally) in sealed bottles with aerobic condition containing a buffer-mineral...

This Test Guideline is designed to assess the toxicity of substances to freshwater aquatic plants of the genus Lemna (duckweed). Exponentially growing plant cultures of the genus Lemna (Lemna gibba and Lemna minor usually) are allowed to grow as monocultures in, at least, five concentrations of...

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 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 describes a procedure for characterising the bioconcentration potential of substances in fish, under flow-through conditions (but semi-static regimes are permissible). The test consists of two phases: the exposure (uptake) and post-exposure (depuration) phases. During the...

The purpose of this Test Guideline is to determine the effects on the reproduction of a substance administered with food to birds.Birds are fed a diet containing the test substance in various concentrations for a period of not less than 20 weeks. A minimum of three dietary concentrations of the...
