Introduction
In the OECD Test Guide, methods for testing the bioaccumulation of environmentally hazardous chemicals include. water flow published in.1996.
Fish test (TG305) and the marine oligochaete bioaccumulation test (TG315) published in.2008. But enriched data on aquatic organisms
It is inferred that the enrichment of terrestrial organisms (such as ticks) is still difficult. Currently, the bioaccumulation assessment of chemicals in soil is based on
It is implemented by a model calculation method for compound lipophilicity, such as the EU Technical Guidance Document.
In addition, the evaluation of secondary poisoning in the terrestrial food chain is also particularly important, the special compartment test method (compartment-specifictest
Method) can meet the needs of this test evaluation. Some international methods that use other organisms other than fish to solve the richness of living organisms
Set problems, such as the use of the American Society for Testing and Materials (Eusenia)
Fetida, Savigny) and pot worms test experimental methods for bioaccumulation of contaminated soils. An internationally recognized standard for the determination of soil
The bioaccumulation test method will help improve the chemical risk assessment of terrestrial ecosystems.
In zopic invertebrates exposed directly to the soil matrix, terrestrial oligochaetes play an important role in maintaining soil structure and function.
use. Terrestrial oligochaetes live in soil and are partially distributed on soil surfaces (especially litter layers), which are usually the most abundant in soil.
Representative of biomass (biomass). By conducting soil bioturbations and preying on other animals, such animals are against other organisms such as invertebrates.
The bioavailability of (predatory crickets and beetles) or vertebrate carnivores (foxes and seagulls) is enormous.
Laboratory soil toxicity and bioaccumulation Lu (LumbricidEarthwormEiseniafetida) and 蚓 (Enchytraeid
PotwormEnchytraeusalbidus) ASTM test guidance provides a lot of weight for the operation of current soil bioaccumulation test methods
Want and useful details. Practical experience and soil bioaccumulation studies and literature publications are also the main sources of information for this standard. This standard
The method is mainly applicable to stable and neutral organic chemicals that are easily adsorbed to the soil. This method may be applied to soil-associated organisms, stable metals
Bioaccumulation test of organic compounds. The method can also be applied to metals and other trace elements.
Bioaccumulation test of chemical terrestrial oligochaetes
1 Scope
This standard specifies the terms and definitions of bioaccumulation tests for terrestrial oligochaetes, test validity, test methods, test procedures, data and
report.
This standard is applicable to the bioaccumulation test of stable, neutral and easily adsorbed organic chemicals. It can be used for soil concomitant and stable.
Metal organic compounds can also be used for bioaccumulation tests of metals and other trace elements.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Bioaccumulation
The concentration of a test substance in a test organism (or a particular tissue) is increased relative to the concentration of the test substance in the test medium.
3.2
Bioconcentration
The increase in the concentration of the test substance in the test organism or on the body surface is relative to the concentration of the test substance in the surrounding medium, and is determined by the test organism.
The result of absorbing the test substance from the surrounding medium (such as absorption through the body surface and absorption by swallowing the soil).
3.3
Biomagnification
The increase in the concentration of the test substance in the living organism or on the body surface, relative to the concentration of the test substance in the food or its food, mainly from the test
The result of an object absorbing the test substance from contaminated food or its food. Biomagnification can lead to the transfer of test substances in the food chain
And accumulation.
3.4
Elimination of elimination
The active or passive loss process of the test substance in the test organism (or specific tissue), and the presence or absence of the test substance in the surrounding medium
Nothing.
3.5
Bioaccumulation factor; BAF
At any time during the absorption phase of the test, the concentration of a test substance (Ca, g·kg-1 test insect net weight) in the test organism (or specific tissue) and
The ratio of the concentration of the substance (Cs, g·kg-1 medium net weight) in the test medium; the unit is kg (medium)·kg-1 (test insect).
3.6
Steady state bioaccumulation factor steadystatebioaccumulationfactor; BAFss
In a steady state, the concentration of a test substance (Ca, g·kg-1 test insect net weight) in the test organism (or specific tissue) and the test medium
