Test No. 204: Fish, Prolonged Toxicity Test: 14-Day Study
This Test Guideline presents guidance for measurement of lethal and other observed effects in fish exposed to test substances. It may be used in place of Test Guideline 203 if a longer observation period is considered useful and appropriate and the ... |
||||
04 Apr 1984 |
Test No. 205: Avian Dietary Toxicity Test
The purpose of this Test Guideline is to determine the effects of a substance administered with food to birds. Birds are fed a diet containing the test substance at a range of concentrations for a period of five days. Two control groups and one ... |
||||
04 Apr 1984 |
Test No. 206: Avian Reproduction Test
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 ... |
||||
04 Apr 1984 |
Test No. 207: Earthworm, Acute Toxicity Tests
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 ... |
||||
17 Aug 2006 |
Test No. 208: Terrestrial Plant Test: Seedling Emergence and Seedling Growth Test
This Test Guideline is designed to assess effects on seedling emergence and early growth of higher plants following exposure to the test substance applied to the soil surface or into the soil. Seeds are placed in contact with soil treated with the ... |
||||
23 Jul 2010 |
Test No. 209: Activated Sludge, Respiration Inhibition Test (Carbon and Ammonium Oxidation)
This Test Guideline is designed to assess the effects of a substance on micro-organisms from activated sludge of waste-water treatment plants by measuring their respiration rate (carbon and/or ammonium oxidation) as oxygen consumption. The test ... |
||||
26 Jul 2013 |
Test No. 210: Fish, Early-life Stage Toxicity Test
The test method described in this Test Guideline, is intended to define the lethal and sub-lethal effects of chemicals on the early life stages of the species tested. The early-life stages of fish are exposed to five concentrations of the test ... |
||||
02 Oct 2012 |
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 ... |
||||
21 Sept 1998 |
Test No. 212: Fish, Short-term Toxicity Test on Embryo and Sac-Fry Stages
In this Short-term Toxicity Test on Fish Embryo and Sac-Fry Stages, the life stages from the newly fertilized egg to the end of the sac-fry stage are exposed. The embryo and sac-fry stages of fish are exposed to five concentrations of the test ... |
||||
21 Sept 1998 |
Test No. 213: Honeybees, Acute Oral Toxicity Test
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 ... |
||||
21 Sept 1998 |
Test No. 214: Honeybees, Acute Contact Toxicity Test
This Test Guideline is a laboratory test method, designed to assess the acute contact toxicity of pesticides and other chemicals to adult worker honeybees. Anaesthetized adult worker honeybees are exposed to five doses in a geometric series of the ... |
||||
21 Jan 2000 |
Test No. 215: Fish, Juvenile Growth Test
This Test Guideline is designed to assess the effects of prolonged exposure to chemicals on the growth of juvenile fish. Juvenile fish in exponential growth phase are placed, after being weighed, in test chambers and are normally exposed to five ... |
||||
21 Jan 2000 |
Test No. 216: Soil Microorganisms: Nitrogen Transformation Test
This Test Guideline describes a laboratory test method designed to investigate the long-term effects of chemicals, after a single exposure, on nitrogen transformation activity of soil microorganisms. Sieved soil is amended with powdered plant meal ... |
||||
21 Jan 2000 |
Test No. 217: Soil Microorganisms: Carbon Transformation Test
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 ... |
||||
04 Jul 2023 |
Test No. 218: Sediment-Water Chironomid Toxicity Using Spiked Sediment

Effects on Biotic Systems
The OECD Guidelines for the Testing of Chemicals is a collection of about 150 of the most relevant internationally agreed testing methods used by government, industry and independent laboratories to identify and characterise potential hazards of chemicals. They are a set of tools for professionals, used primarily in regulatory safety testing and subsequent chemical and chemical product notification, chemical registration and in chemical evaluation. They can also be used for the selection and ranking of candidate chemicals during the development of new chemicals and products and in toxicology research. This group of tests covers effects on biotic systems.
