The different fractionation protocols may offer different chemical information on biologically available element content of compost, however, only to the BCR sequential extraction scheme is available a sediment type certificated reference material for validation the fractionation procedure. For soils, composts CRM samples are available only for single step extraction or digestion procedures.
In our preliminary studies application of different fractionation methods was widely used for sediment, soil and other solid environmental samples (e.g. red mud). The aim of our recent study is the preparation of compost reference material for total and releasable heavy metal analysis. For this aim a green compost sample was selected and about 50 kg was homogenized. An inter-laboratory comparison will be organized for determination of total soluble and biologically available heavy metal content. In our laboratory for multielemental analysis ICP-OES method will be applied using different extraction protocols for fractionation. (Lakanen Erviö, BCR, Hungarian Standard: MSZ- 21470-50:1998)

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.
