    Test No. 508: Magnitude of the Pesticide Residues in Processed Commodities

    This Test Guideline describes how to plan and carry out processing studies, i.e. determine residue levels in primary processed commodities following pesticide application on raw agriculture commodities (RAC) under conditions likely to lead to maximum residues. It provides the distribution of residues (active ingredient, and/or metabolites, degradation products), and preferential accumulation in various processed products resulting

    Test No. 315: Bioaccumulation in Sediment-dwelling Benthic Oligochaetes

    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 stable metallo-organic compounds which tend to associate with sediments.

    The test consists of two phases. During the uptake phase,

    Test No. 314: Simulation Tests to Assess the Biodegradability of Chemicals Discharged in Wastewater

    This Test Guideline describes a method to assess the extent and kinetics of primary and ultimate biodegradation of organic chemicals whose route of entry into the environment begins with their discharge to wastewater. It consists of five simulation tests in a) sewer systems, b) activated sludge, c) anaerobic digester sludge, d) treated effluent in the mixing zone of surface water, and e) untreated wastewater that is directly

    Test No. 228: Determination of Developmental Toxicity of a Test Chemical to Dipteran Dung Flies(Scathophaga stercoraria L. (Scathophagidae), Musca autumnalis De Geer (Muscidae))

    This Test Guideline describes a method to estimate the developmental toxicity of a test chemical to the dung dwelling life stages of dung-dependent dipteran species. Two test species can be used. The test chemical is mixed with bovine faeces, to which either 10 eggs of Scathophaga stercoraria or 10 larvae of Musca autumnalis are added. The test will be terminated 5 days after emergence of the last adult in the

    Test No. 226: Predatory mite (Hypoaspis (Geolaelaps) aculeifer) reproduction test in soil

    This Test Guideline describes a method to assess the effects of chemical substances in soil on the reproductive output of the soil mite species Hypoaspis (Geolaelaps) aculeifer Canestrini (Acari: Laelapidae). It can be used for water soluble or insoluble substances, but not with volatile substances.

    Adult females of similar age are exposed to a range of concentrations of the test substance mixed into 20 g dry mass

    Test No. 211: Daphnia magna Reproduction Test

    The test method described in this Test Guideline assesses the effect of chemicals on the reproductive output of Daphnia magna Straus. To this end, young female Daphnia are exposed to the test substance added to water at a range of concentrations (at least five). For semi-static tests, at least 10 animals at each test concentration and for flow-through tests, 40 animals divided into four groups of 10 animals at each test

    Test No. 407: Repeated Dose 28-day Oral Toxicity Study in Rodents

    This method provides information on health hazard likely to arise from exposure to test substance via oral administration. The method is based on the repeated oral administration of the substance of interest during one limited period (one dose level daily during 28 days). This Guideline is intended primarily for use with rodents (rat preferably). At least 10 animals (5 female and 5 male) should be used for each dose level. Three

    Test No. 425: Acute Oral Toxicity: Up-and-Down Procedure

    The method permits estimation of an LD50 with a confidence interval and the results allow a substance to be classified for acute toxicity according to the Globally Harmonised System of classification and labelling of chemicals.

    It is easiest to apply to materials that produce death within couple of days. This Test Guideline is intended for use with rodents (rat female preferably). There are a limit test and a main test. The
