Soil properties of coal, iron and steel industrial sites in Essen The physical and chemical soil properties of some Urbic Anthrosols derived from technogenic substrata in the study area Essen (Northrhine-Westfalia, Germany) were analyzed with special consideration of toxic elements. The sites are characterized by high contents of coarse fragments (> 2 mm) of different species and size whereby this fragments are partly porous. Bulk densities and particle densities are low due to the high contents of carbon. The sites show high pH-values with the exception of sulphur containing mining substrata, which are characterized by low pH-values in consequence of pyrite oxidation. Partly the technogenic substrata have a high content of carbon, especially of coal, before depositing. There are high contents of anorganic and organic toxic elements in some horizons due to the deposit species, e.g. high Cr-values in horizons with steel industrial slags and high PAH-values in horizons with coal tar containing material. 相似文献

A turf-banked lobe with a ground soil of post-Pinedale age overlies a buried paleosol which, although thin, appears to have been developed in situ. Organic matter from the Ab horizon of the paleosol yields a radiocarbon age of BP (Gak-3823) which corresponds with the waning stages of the Pinedale Glaciation in the Rocky Mountains. Abundant kaolinite and high amounts of silt and clay suggest that it may have developed over a long time interval. 相似文献
