The present study was conducted in the northern outskirts of the Jaworzno town situated in the Upper Silesia, the most industrialized part of Poland, where the over hundred-year-old landfill site of soda ash waste is situated. The 10 waste samples and 10 topsoil samples were collected. Value of the pH and the total load of selected heavy metals (Cd, Cr, Pb and Zn) were determined for both types...

The aim of this study is to model downward migration of lead from the plow layer of an experimental site located in Versailles (about 15 km southwest of Paris, France). Since 1928, samples have been collected annually from the topsoil of three control plots maintained in bare fallow. Thirty samples from 10 different years were analyzed for their lead and scandium contents and lead isotopic comp...

1. ABSTRACT Thc effects of adding various soil amendments and a pyrite oxidation inhibitor to aid in the establishment of vegetation and to reduce acid drainage (AD) from coal fly ash and coal reject (FA + CR*) were assessed in an outdoor mesocosm study. Preliminary greenhouse experiments and field observations at the U.S. Department of Energy's Savannah River Site (SRS) indicated that plants w...

Surface and soil core samples from northeast China were analyzed for Pu isotopes. The measured (240)Pu/(239)Pu atomic ratios and (239 + 240)Pu/(137)Cs activity ratios revealed that the global fallout is the dominant source of Pu and (137)Cs at these sites. Migration behavior of Pu varying with land type and human activities resulted in different distribution of Pu in surface soils. A sub-surfac...

Statistically veri®ed composite ®ngerprints and a multivariate mixing model have been employed to establish the main sources of the suspended sediment transported through the lower, non-tidal reaches of the River Ouse and one of its main tributaries, the River Wharfe, during the period 1994±1997. In the case of the suspended sediment samples collected from the River Ouse, the load-weighted mean...

Fungi play fundamental ecological roles in terrestrial ecosystems. However, their distribution and diversity remain poorly described in natural communities, particularly in arid and semi-arid ecosystems. In order to identify environmental factors determining fungal community structure in these systems, we assessed their diversity in conjunction with soil physicochemical characteristics in a sem...

The Heterogeneous Tool Set (HETS) is the main analysis tool for the specification language heterogeneous CASL. Heterogeneous CASL (HETCASL) combines the specification language CASL [6, 28] with CASL extensions and sublanguages, as well as completely different logics and even programming languages such as Haskell. HETCASL (see Fig. 1 for a simple subset) extends the structuring mechanisms of CAS...

Pulp and paper mill sludges have many attributes which, when utilized as a soil amendment, can improve soil fertility and overall soil quality. The primary objective of this study was to evaluate the use of pulp sludge as the organic matter component in a manufactured topsoil. Seven manufactured topsoils, containing 5.1, 8.8, 9.6, 10.9, or 13.8% pulp sludge and 0, 8.4, or 20.7% flume grit on a ...

The concept of school sport on which we are basing our experience is set in the Historical Territory of Bizkaia (Basque Country, Spain) and this is regulated by Bizkaia’s Diputación Foral (Provincial Council), governed by the regional regulations of the Basque Government. This government takes the view that School Sport covers sport activities at teaching centres outside actual school teaching ...

Combustion-derived black carbon has received attention as a form of refractory organic carbon that may be preferentially preserved in soils and sediments. However, little is understood about the environmental roles of black carbon in urban soils. This investigation represented the preliminary study to characterize black carbon (BC) concentrations and enrichment ratios in Xuzhou urban roadside t...
