Details on test organisms:

TEST ORGANISM
- Common name: earthworm
- Source: own breeding, original source was the Bundesanstalt für Land und Forstwirtschaft.
- Weight at test initiation: 0.30 - 0.60 g

Housing:
- Housing conditions: Organisms were bred at the testing facility in covered plasitc vessels (volume 60 L) containing potting compost at 20 ± 2°C in the dark

ACCLIMATION

Study design

Study type:

laboratory study

Substrate type:

artificial soil

Limit test:

no

Total exposure duration:

14 d

Test conditions

Test temperature:

20 ± 2 °C

Details on test conditions:

TEST SYSTEM
- Test container (material, size): glass dishes, 1 L volume
- Amount of soil or substrate:
- No. of organisms per container (treatment): 10
- No. of replicates per treatment group: 4
- No. of replicates per control: 4


SOURCE AND PROPERTIES OF SUBSTRATE (if soil)
- Composition (if artificial substrate):
10% peat
20% kaolin
70 % quartz sand
0.4 % calcium carbonate
- Organic carbon (%):
- Pretreatment of soil: deionised water was added to give a overall moisture content of about 25 % of dry weight. The definitive moisture content, determinated the day before application by drying a sample at 105 °C and re-weighing, was 16.3 %.
