These contaminations originate from the gas purification p process that was conducted inManufactured Gas Plants (MGP).There is a risk of human threat depending on the stability dissolved iron-cyanide complexes due to the potential release of toxic free cyanide, CN(aq) and HCN(g), (aq). The aim of this thesis was to evaluate a new method for the cyanide detection and to investigate the stability and retardation of the iron-cyanide complexes in soils by batch and column experiments in order to improve the knowledge concerning the fate of cyanide compounds in soil and groundwater. This study seeks for enhancing the efficiency of phytoremediation as a proper approach to decontaminate ironcyanides complexes and thus tries to make a contribution to environmental protection.}, language = {en} } @inproceedings{SutLohmannRaab, author = {Sut-Lohmann, Magdalena and Raab, Thomas}, title = {Feasibility of diffuse reflectance infrared Fourier spectroscopy (DRIFTS) to quantify iron-cyanide (Fe-CN) complexes in soil}, series = {European Geosciences Union, General Assembly 2017, Vienna, Austria}, booktitle = {European Geosciences Union, General Assembly 2017, Vienna, Austria}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, abstract = {Contaminated sites create a significant risk to human health, by poisoning drinking water, soil, air and as a consequence food. Continuous release of persistent iron-cyanide (Fe-CN) complexes from various industrial sources poses a high hazard to the environment and indicates the necessity to analyze considerable amount of samples. At the present time quantitative determination of Fe-CN concentration in soil usually requires a time consuming two step process: digestion of the sample (e.g., micro distillation system) and its analytical detection performed, e.g., by automated spectrophotometrical flow injection analysis (FIA). In order to determine the feasibility of diffuse reflectance infrared Fourier spectroscopy (DRIFTS) to quantify the Fe-CN complexes in soil matrix, 42 soil samples were collected (8 to 12.520 mg kg-1CN) indicating single symmetrical CN band in the range 2092 - 2084 cm-1. Partial least squares (PLS) calibration-validation model revealed IR response to CNtot exceeding 1268 mg kg-1 (limit of detection, LOD). Subsequently, leave-one-out cross-validation (LOO-CV) was performed on soil samples containing low CNtot (<900 mg kg-1), which improved the sensitivity of the model by reducing the LOD to 154 mg kg-1. Finally, the LOO-CV conducted on the samples with CNtot >900 mg kg-1 resulted in LOD equal to 3494 mg kg-1. Our results indicate that spectroscopic data in combination with PLS statistics can efficiently be used to predict Fe-CN concentrations in soil. We conclude that the protocol applied in this study can strongly reduce the time and costs essential for the spatial and vertical screening of the site affected by complexed Fe-CN.}, language = {en} } @misc{SutLohmannRaab, author = {Sut-Lohmann, Magdalena and Raab, Thomas}, title = {Quick detection and quantification of iron-cyanide complexes using fourier transform infrared spectroscopy}, series = {Environmental Pollution}, volume = {227}, journal = {Environmental Pollution}, issn = {0269-7491}, doi = {10.1016/j.envpol.2017.04.052}, pages = {64 -- 72}, abstract = {The continuous release of persistent iron-cyanide (Fe-CN) complexes from various industrial sources poses a high hazard to the environment and indicates the necessity to analyze a considerable amount of samples. Conventional flow injection analysis (FIA) is a time and cost consuming method for cyanide (CN) determination. Thus, a rapid and economic alternative needs to be developed to quantify the Fe-CN complexes. 52 soil samples were collected at a former Manufactured Gas Plant (MGP) site in order to determine the feasibility of diffuse reflectance infrared Fourier spectroscopy (DRIFTS). Soil analysis revealed CN concentrations in a range from 8 to 14.809 mg kg⁻¹, where 97\% was in the solid form (Fe₄[Fe(CN)₆]₃), which is characterized by a single symmetrical CN band in the range 2092-2084 cm-1. The partial least squares (PLS) calibration-validation model revealed IR response to CNtot which exceeds 2306 mg kg⁻¹(limit of detection, LOD). Leave-one-out cross-validation (LOO-CV) was performed on soil samples, which contained low CNtot (<900 mg kg⁻¹). This improved the sensitivity of the model by reducing the LOD to 154 mg kg⁻¹. Finally, the LOO-CV conducted on the samples with CNtot > 900 mg kg⁻¹ resulted in LOD equal to 3751 mg kg⁻¹. It was found that FTIR spectroscopy provides the information concerning different CN species in the soil samples. Additionally, it is suitable for quantifying Fe-CN species in matrixes with CNtot > 154 mg kg⁻¹. Thus, FTIR spectroscopy, in combination with the statistical approach applied here seems to be a feasible and quick method for screening of contaminated sites.}, language = {en} } @misc{SutLohmannBoldtBurischPohleetal., author = {Sut-Lohmann, Magdalena and Boldt-Burisch, Katja and Pohle, Ina and Raab, Thomas}, title = {Advancing performance of green technologies for remediation and reclamation of degraded urban soils}, publisher = {United Nations University, Institute for Integrated Management of Material Fluxes and of Resources}, address = {Dresden}, isbn = {978-3-944863-18-4}, pages = {S. 61}, language = {en} } @inproceedings{SutLohmannRepmannFischeretal., author = {Sut-Lohmann, Magdalena and Repmann, Frank and Fischer, Thomas and Raab, Thomas}, title = {Retardation of iron-cyanide complexes in soils of a former Manufactured Gas Plant site}, series = {Book of abstracts, XII International Congress of Young Chemists, YoungChem2014, Szczecin, Poland 8th-12th October 2014}, booktitle = {Book of abstracts, XII International Congress of Young Chemists, YoungChem2014, Szczecin, Poland 8th-12th October 2014}, address = {Warsaw}, isbn = {978-83-61037-28-6}, pages = {S. 44}, language = {en} } @misc{SutLohmannKnoopRaab, author = {Sut-Lohmann, Magdalena and Knoop, Christine and Raab, Thomas}, title = {Effect of the post treatments for biowaste-based digestateson water solubility of nutrients and iron-cyanide (Fe-CN)complex mobility}, series = {Land Degradation \& Development}, volume = {30}, journal = {Land Degradation \& Development}, number = {13}, issn = {1099-145X}, doi = {10.1002/ldr.3336}, pages = {1545 -- 1553}, abstract = {With recent policy developments, an increase in organic waste utilization is expected. However, the use of organic amendments to reduce the mobility of iron-cyanide (Fe-CN) complexes and simultaneously promote vegetation growth has not been studied before. Therefore, we evaluated the effect of (a) drying, (b) composting, and (c) pelletizing on the ability of digestates (biowastes from an anaerobic treatment of municipal organic waste) to provide easily available nutrients and stabilize Fe-CN complexes. Extraction with deionized water resulted in a considerably higher nutrient and carbon elution from air-dried and oven-dried digestates (50\% dry matter [DM] of total K, 11\% DM Mg, 7\% DM Ca, and 6\% DM C). Mixer-pelletized digestates stand out among the composted samples (42\% of total K, 3\% DM C, 5\% DM P, 1.5\% DM Mg, and 1\% DM Ca). The adsorption experiment showed the highest significant tot. CN conc. reduction using noncomposted, air-dried (100\%), and oven-dried (82\%) digestates. Significant correlations have been found for Mg, Ca, and dissolved organic carbon elution and slightly acidic pH as well as CN adsorption. The Fourier transform infrared analysis revealed Fe-CN complexation on inorganic (K₂Mn[Feᴵᴵ(CN)₆] and NH₄Fe[Feᴵᴵ(CN)₆]) and organic constituents indicating formation of nitriles. Air- and oven-dried digestates showed the most promising results in terms of nutrients' availability and ability to decrease Fe-CN complex mobility.}, language = {en} } @misc{SutLohmannJonczakRaab, author = {Sut-Lohmann, Magdalena and Jonczak, Jerzy and Raab, Thomas}, title = {Phytofiltration of chosen metals by aquarium liverwort (Monosoleum tenerum)}, series = {Ecotoxicology and Environmental Safety}, volume = {Vol. 188}, journal = {Ecotoxicology and Environmental Safety}, issn = {1090-2414}, doi = {10.1016/j.ecoenv.2019.109844}, pages = {7}, abstract = {Aquatic bryophytes are widely used as indicators of water pollution with various substances, including metals. We present a first study concerning the feasibility of Monosoleum tenerum to remove potentially toxic metals Zn, Cu, Ni, Mn and Fe from water. The novel approach to study the bioaccumulation under controlled conditions and in vitro grown aquarium liverworts was applied. The plants were exposed to 1, 10 and 100 ppm multi-metal solution for 7 days and subsequently the metal content was determined in plant material and media to calculate the bioaccumulation factor (BAF). The study revealed various accumulation behavior (metal and dose dependent), which followed the order of Cu > Zn > Mn > Ni > Fe for 1 ppm; Zn > Cu > Mn > Fe > Ni for 10 ppm and Cu > Fe > Zn > Ni > Mn for 100 ppm solution. However, with increasing Cu, Mn and Ni concentration in the solution, BAF decreased. For Zn the highest BAF value (136) was obtained for the 10 ppm solution. Fe bioaccumulation increased with the increasing solution concentration. After 7 week exposure, the results indicated highest accumulation of Cu (3,25 mg) followed by Fe (1,8 mg) in the plant tissue for the 100 ppm solution. Overall, the bryophyte M. tenerum demonstrate high potential for the removal of toxic metals from the multi-metal solution via accumulation in plant tissue. The BAF values were proper to indicate the use of M. tenerum for phytofiltration of waste waters affected by Zn, Cu, Ni, Mn and Fe.}, language = {en} } @misc{SutLohmannJonczakParzychetal., author = {Sut-Lohmann, Magdalena and Jonczak, Jerzy and Parzych, Agnieszka and Šimansk{\´y}, Vladim{\´i}r and Poll{\´a}kov{\´a}, Nora and Raab, Thomas}, title = {Accumulation of airborne potentially toxic elements in Pinus sylvestris L. bark collected in three Central European medium-sized cities}, series = {Ecotoxicology and Environmental Safety}, volume = {200}, journal = {Ecotoxicology and Environmental Safety}, issn = {0147-6513}, doi = {10.1016/j.ecoenv.2020.110758}, pages = {11}, language = {en} } @misc{JonczakJankiewiczKondrasetal., author = {Jonczak, Jerzy and Jankiewicz, Ursula and Kondras, Marek and Kruczkowska, Bogusława and Oktaba, Lidia and Oktaba, Jarosław and Olejniczak, Izabella and Pawłowicz, Edyta and Poll{\´a}kov{\´a}, Nora and Raab, Thomas and Regulska, Edyta and Słowińska, Sandra and Sut-Lohmann, Magdalena}, title = {The influence of birch trees (Betula spp.) on soil environment - A review}, series = {Forest Ecology and Management}, volume = {477}, journal = {Forest Ecology and Management}, issn = {0378-1127}, doi = {10.1016/j.foreco.2020.118486}, pages = {13}, language = {en} } @misc{KlosSutLohmannRaabetal., author = {Klos, Friederike and Sut-Lohmann, Magdalena and Raab, Thomas and Hirsch, Florian}, title = {Innovative Drone-based Hyperspectral Detection of Heavy Metals (Ni, Zn, and Cu) in Plants cultivated for Phytomining}, series = {EGU General Assembly 2020, Online | 4-8 May 2020}, journal = {EGU General Assembly 2020, Online | 4-8 May 2020}, doi = {10.5194/egusphere-egu2020-9370}, language = {en} } @misc{SutLohmannKnoopRaab, author = {Sut-Lohmann, Magdalena and Knoop, Christine and Raab, Thomas}, title = {Effect of drying, composing and pelletizing of biowaste-based digestates on providing water soluble nutrients and stabilizing iron-cyanide (Fe-CN) complexes}, series = {EGU General Assembly 2020, Online | 4-8 May 2020}, journal = {EGU General Assembly 2020, Online | 4-8 May 2020}, doi = {10.5194/egusphere-egu2020-8013}, language = {en} } @misc{JonczakSutLohmannPollakovaetal., author = {Jonczak, Jerzy and Sut-Lohmann, Magdalena and Poll{\´a}kov{\´a}, Nora and Parzych, Agnieszka and Šimansk{\´y}, Vladim{\´i}r and Donovan, Sally and Medinski, Tetiana}, title = {Comparison of bioaccumulation potential of eleven pine species in low polluted ecosystem}, series = {EGU General Assembly 2020, Online | 4-8 May 2020}, journal = {EGU General Assembly 2020, Online | 4-8 May 2020}, doi = {10.5194/egusphere-egu2020-8746}, language = {en} }
