The earthworm (Lumbricidae family) can be used in many ecotoxicological tests as a bio indicator and as a soil index in organic agriculture. Earthworms show the greatest rate of metals accumulation among all other species of terrestrial ecosystems. The main objective of our study was to study the accumulation of alluminum in the tissues of the earthworms from organic fields.
Earthworms have been collected from organic fields, in Central Greece and were separated into 4 groups and hatched for a period of 8 weeks in receptacles with soil substrate of various Al concentrations (0, 1000, 2000, 4000 mg kg -1 of soil) following randomized block experiment design. The measurement of Al concentration in their tissues was conducted via the method of individual absorption. According to the above results no change in the concentration of alluminum in the animal tissues is observed in relation with the alluminum concentration increase in the soil. A higher accumulation of alluminum in the tissues was observed only when the Al concentration in the soil was also the highest (4000mg kg-1).

Transformatives Klimarecht: Raum, Zeit, Gesellschaft

This article contends that climate law should be conceived as inherently transformative in a double sense. The law not only guides the necessary transformation of economy and society, but is itself undergoing transformation.
