Regenerative Energie
Both continuous infiltration experiments over a period of 2 years, run-off experiments in summer 2000 were carried out in order to investigate the behaviour of EDCs in agricultural soils after sewage sludge application.
The soils were either loaded with double deionised water, digested sludge, EDC spiked digested sludge, or solely a mixed EDC solution containing 4-nonylphenol, 4-tert-octylphenol (OP), bisphenol A, 17â-estradiol, and 17á-ethynylestradiol (EE2). In infiltration experiments, dislocation of alkylphenols and EE2 towards lower soil horizons was observed. For example, 125 µg/kg of OP and 60 µg/kg of EE2 were determined in the depth of 20 – 30 cm of a sandy soil. In most cases, EDC concentrations decreased with increasing soil depths. No considerable EDC concentrations were detected in the leachate. We conclude that adsorption to the soil matrix and/or biodegradation prevented a direct EDC transport to groundwater. In run-off experiments one sandy soil and one loamy soil were studied. The results demonstrate an extensive transport of EDCs with run-off water. EDC mass fluxes washed off the sandy soil were higher than those washed off the loamy soil, except in the case of EE2 which showed an inverse behaviour. Adsorption of EDCs to soil was more extensive in loamy soil than in sandy soil.

Rechtliche und praktische Unsicherheiten bei der Durchführung des europäischen Klimaanpassungsrechts durch das Bundes- Klimaanpassungsgesetz (KAnG)

In the context of the European Climate Law (EU) 2021/1119), the Governance Regulation (EU) 2018/1999 and the Nature Restoration Regulation (EU) 2024/1991, the KAnG came into force on July 1, 2024.
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.
