Cyanide is a potentially toxic substance and its presence in soil and groundwater may cause risk for human health as well as for the environment. MGPs were commonly built on the city suburban areas, which have spread ever since. Nowadays, these sites are typically located in inner cities, causing environmental thread, due to the leaching of pollutants. More recently, columns and batch experiments have been used to study fate and mobility of contaminants is soil. The release of iron-cyanide complexes under unsaturated flow conditions was evaluated with eight columns of 30 cm length and a diameter of 5,4 cm. Cyanide concentrations in the collected leachates were measured with Flow Injection Analysis (FIA). Additionally pH, electrical conductivity (EC) and various ion concentrations were determined. In order to compare the release of Fe-CN complexes in saturated conditions a batch experiment was conducted, where in defined time intervals, 1 ml of the extract water phase was analyzed for CN concentration. Study revealed an analogous trend of cyanide release in both experiments indicating primarily the release of formerly dissolved phase (hexacyanoferrates) followed by continual dissolution of ferric ferrocyanide. We conclude that batch experiments, conducted prior to column analysis, can serve as preliminary prediction of the water soluble cyanide fraction under unsaturated conditions.}, language = {en} } @inproceedings{SutLohmannFischerRepmannetal., author = {Sut-Lohmann, Magdalena and Fischer, Thomas and Repmann, Frank and Raab, Thomas}, title = {Feasibility of field portable near infrared (NIR) spectroscopy to determine cyanide concentrations in soil}, series = {European Geosciences Union, General Assembly 2013, Vienna, Austria, 07 - 12 April 2013}, booktitle = {European Geosciences Union, General Assembly 2013, Vienna, Austria, 07 - 12 April 2013}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, abstract = {In Germany, at more than 1000 sites, soil is polluted with an anthropogenic contaminant in form of iron-cyanide complexes. These contaminations are caused by former Manufactured Gas Plants (MGPs), where electricity for lighting was produced in the process of coal gasification. The production of manufactured gas was restrained in 1950, which caused cessation of MGPs. Our study describes the application of Polychromix Handheld Field Portable Near-Infrared (NIR) Analyzer to predict the cyanide concentrations in soil. In recent times, when the soil remediation is of major importance, there is a need to develop rapid and non-destructive methods for contaminant determination in the field. In situ analysis enables determination of 'hot spots', is cheap and time saving in comparison to laboratory methods. This paper presents a novel usage of NIR spectroscopy, where a calibration model was developed, using multivariate calibration algorithms, in order to determine NIR spectral response to the cyanide concentration in soil samples. As a control, the contaminant concentration was determined using conventional Flow Injection Analysis (FIA). The experiments revealed that portable near-infrared spectrometers could be a reliable device for identification of contamination 'hot spots', where cyanide concentration are higher than 2400 mg kg-1 in the field and >1750 mg kg-1 after sample preparation in the laboratory, but cannot replace traditional laboratory analyses due to high limits of detection.}, language = {en} } @incollection{KruemmelbeinZeihser, author = {Kr{\"u}mmelbein, Julia and Zeihser, Uwe}, title = {Landwirtschaftliche Versuchsfl{\"a}che Tagebau J{\"a}nschwalde - Versuchsdesign und Fl{\"a}chenherstellung}, series = {Energieholzproduktion und bodenphysikalische Untersuchungen auf Rekultivierungsfl{\"a}chen des Niederlausitzer Braunkohlereviers}, booktitle = {Energieholzproduktion und bodenphysikalische Untersuchungen auf Rekultivierungsfl{\"a}chen des Niederlausitzer Braunkohlereviers}, editor = {Kr{\"u}mmelbein, Julia and Raab, Thomas and H{\"u}ttl, Reinhard F.}, publisher = {BTU}, address = {Cottbus}, isbn = {978-3-937728-12-4}, pages = {3 -- 15}, language = {de} } @inproceedings{FischerSproeteVesteetal., author = {Fischer, Thomas and Spr{\"o}te, Roland and Veste, Maik and Wiehe, Wolfgang and Lange, Philipp and Bens, Oliver and Raab, Thomas and H{\"u}ttl, Reinhard F.}, title = {Functions of biological soil crusts on central European inland dunes:Water repellency and pore clogging influence water infiltration}, series = {EGU General Assembly 2010, held in Vienna, Austria, 02 - 07 May 2010}, booktitle = {EGU General Assembly 2010, held in Vienna, Austria, 02 - 07 May 2010}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @inproceedings{SproeteFischerVesteetal., author = {Spr{\"o}te, Roland and Fischer, Thomas and Veste, Maik and Lange, Philipp and Bens, Oliver and Raab, Thomas and H{\"u}ttl, Reinhard F.}, title = {Hydrophobicity in sandy soils triggered by the development of Scots Pine stands in southern Brandenburg, Germany}, series = {EGU General Assembly 2010, held in Vienna, Austria, 02 - 07 May 2010}, booktitle = {EGU General Assembly 2010, held in Vienna, Austria, 02 - 07 May 2010}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @misc{SutLohmannFischerRepmannetal., author = {Sut-Lohmann, Magdalena and Fischer, Thomas and Repmann, Frank and Raab, Thomas and Dimitrova, Tsvetelina}, title = {Feasibility of field portable near infrared (NIR) spectroscopy to determine cyanide concentrations in soil}, series = {Water, Air and Soil Pollution}, volume = {223}, journal = {Water, Air and Soil Pollution}, number = {8}, issn = {1573-2932}, doi = {10.1007/s11270-012-1298-y}, pages = {5495 -- 5504}, abstract = {Vicinities of manufactured gas plants were often contaminated with solid iron-cyanide complexes as a result of the coal gasification process.

Rapid and non-destructive field methods for contaminant determination permit an analysis of large sample numbers and hence, facilitate identification of 'hot spots' of contamination. Diffuse near infrared reflectance spectroscopy has proven to be a reliable analytical tool in soil investigation. In order to determine the feasibility of a Polychromix Handheld Field Portable Near-Infrared Analyzer (FP NIR), various sample preparation methods were examined, including homogenizing, sieving, drying, and grinding. Partial least squares calibration models were developed to determine near infrared (NIR) spectral responses to the cyanide concentration in the soil samples.
