REsEaRch topics in thE woRking gRoup EnviRonmEntal and soil chEmistRy ENVIRONMENTAL AND SOIL CHEMISTRYThe working group of Environmental and Soil Chemistry follows various research to-pics in which you always have the possibility to work in a short-term project, to write a case study or bachelors / masters / diploma thesis and participate in current research projects.The different research questions are answered with different methods. Some require a preliminary data sampling in the field which are treated in the laboratory afterwards, others are based in the lab only. However, pure literature work is possible, too.The following pages will introduce you into the different research topics and the scientific staff. Please do not hesitate to ask the displayed contact persons for more information.January 2012 Howtodistinguishbetweentotalcontentandthebioavailableconcentrationofemergingsubstancesinsoilsandsediments?Besides monitoring and measuring concentrations in the environment, one major issue of environmental chemical analyst is the development and application of new me-thods to get better insieght on the fate and risk of pollu-tants in the environment. It is commonly accepted that simple determination of total concentrations does not reflect the risk and that the behavior of the compounds under environmental conditions which determines e.g. the bio availability has to be investigated.EnviRonmEntal analytics ENVIRONMENTAL AND SOIL CHEMISTRY Research topics for Bachelor/Master/Diploma thesis/Case Studies:Contact person:Dr. Nicole Bandowbandow@uni-landau.de Methoddevelopmentfor2Dseparationofnanoparticlesviacouplinghydrodynamic,electrophoreticandspectro-scopictechniques.Engineered inorganic nanoparticels (EINP) are con-tinously being released into the environment. Risk assessment is, however, currently hampered by the lack of suitable methods to detect nanoparticles in the environment. Research Topics for Bachelor/Master/Diploma thesis/Case Studies:Contact person:Denis Rakcheevrakcheev@uni-landau.denanopaRticlEs in thE EnviRonmEnt ENVIRONMENTAL AND SOIL CHEMISTRYBackground:During the last decade the production of engineered inorganic nanoparticles (EINP) has steadily incre-ased and today they can be found in a multitude of daily use products such as cosmetics or textiles. Although increasing research activity focuses on the fate of EINP in the environment, there is still a big gap of knowledge with respect to their transformation and mobility in the environment. Thus, we currently investigate engineered nanoparticles and their interactions with natural organic matter, soils and (in)organic surfaces via a combination of several chromatographic, microscopic and light scattering techniques.

We refer to ecologically and socially relevant topics, for example nanotechnology, renewable energy or green genetic technology.The below offered theses are literature based studies where you e.g. analyze the environmental know-ledge in the scientific literature and compare this with the content in the media.

Parts of the water meadows of Landau (Wsserwiesen) have been regularly flooded for more than 500 years with yet unknown impact on the ecosystem.Comparison of e.g., soil characteristics, vegetation patterns and biodiversity of these areas allows a direct investigation of the effect of hydrological alterations on the terrestrial ecosystem. We hypothe-size that the continuous alteration between reducing and oxidizing conditions in the regularly flooded meadows may have led to an accumulation of soil organic matter (SOM) with different properties with respect to the non-flooded fields. Furthermore the regular shrinking and swelling of the soil can change nature of binding of organic pollutants and thus their bio availability.

In Palestinian Authorities and Israel waste water as e.g. pre-treated water from waste water treatment plants or water of olive oil mills is often re-used. Despite the positive effects as high nutrient content and water supply possible negative effects as decreased water holding capacity, salinization and quality of soil organic matter of this practice are rather unknown.

Plantgrowthexperiments.Maintaining soil fertility is one of the most urgent human problems on earth. It is estimated that up to 40% of the worlds agricultural land is seriously degraded. Fertilizers: To ensure food supply for the growing world population agriculture depends on an increasing consumption of fertilizers. Unfortunately, fertilizers do not only contain the basic (N, P, K), secondary (e.g. Ca, Mg, S), and micro-nutrients (e.g. Zn, Fe, Mo and Na). They may also contain traces of contami-nants like Uranium and heavy metals like Cd, Pb and As which with increasing fertilizer supply may enrich in the soils. Therefore possible pathways of Uranium deriving from fertilizers in soils are of special interest.FERtilizERs and othER soil amEndmEnts ENVIRONMENTAL AND SOIL CHEMISTRYBackground: Research topics for Bachelor/Master/Diploma thesis/Case Studies: Contact person:Dr. Mohamed Azeroualazeroual@uni-landau.de ThermalbehaviorandsurfacepropertiesofTerrapretasubstrate ChangesoforganicmatterstabilityduringtheproductionprocessTerra preta is a black soil probably anthropogenically developed in former In-dian cultures in Amazonia. It has a long lasting fertility of more than 1000 years even under the extreme Amazonian climate. Palatine researchers successfully produced this organic rich material. The so-called Terra preta substrate has a high water holding and nutrient binding capacity which is supposed to be related to the stability of the organic substrate. Therefore it is planned to use Terra preta substrates, e.g., on degraded soils to re-establish an organic matter layer and re-enable plant growth. Research topics for Bachelor/Master/Diploma thesis/Case studies:Contact persons:Dr. Jette Schwarzschwarzj@uni-landau.deDr. Drte Diehldiehl@uni-landau.de soil oRganic mattER (som) ENVIRONMENTAL AND SOIL CHEMISTRYSoil is a highly complex, heterogeneous and chemically ill-defined system. Organic matter regimes in soil serve for various biological and physico-chemical processes. Water plays a key role in several pro-cesses by direct and indirect involvements. Water molecules are hypothesized to bridge between orga-nic matter segments to form cross-links between the molecules. This can affect the SOM stability and uptake and release of small molecules including pollutants. A better understanding of the mechanism that water molecules undergo will open a better way to control soil pollution and enhance remediation technologies.
