Genetic polymorphisms and variability of cytochrom P450 enzymes (Project)
Susceptibility towards xenobiotics (e.g. chemicals, additives, biozides) can be either genetically determined ore influenced by environmental factors and genetic variability may not necessarily be reflected on the phenotype level. The principle of metabolic activation represents the basis for the project: in most cases, metabolic activiation by xenobiotic metabolizing enzymes is the prerequisite...

FOR 536 P1: Amount, composition, and turnover of organic matter pools in grassland soils under typical steppe vegetation types of the Xilin River Basin (Inner Mongolia) with different grazing management (Project)
Heavy grazing in Leymus chinensis-dominated semi-arid grasslands results in changes in the amount, composition, and turnover of soil organic matter (SOM), due to the degradation of soil aggregation and release of aggregate-protected SOM, associated with enhanced susceptibility to soil erosion. This becomes evident as reduced bulk soil OC content, but especially as reduced microaggregation and...

FOR 536 P2: Nitrogen supply of grassland and its belowground productivity as influenced by stocking rate, management and availability of water (Project)
Above and belowground net primary productivity of grassland communities in the Xilingol steppe is highly variable, and previous studies have shown that the availability of water and nitrogen as well as the grazing intensity are the governing factors. In continuation of previous studies initiated by the late Prof. Sattelmacher and by Dr. Brück, the general focus in this project will remain on the...

Development of a simple and universal analytical method for the simultaneous determination of pesticides in tap water (Project)
Nowadays, the use of liquid chromatography combined with tandem mass spectrometry (LC-MS/MS) simplifies the determination of pesticide residues in food. Its application in tap water analysis should be proven. If LC-MS/MS is useful for the determination of pesticides in tap water, the registration process of pesticides can be accelerated, because additional studies of the applicant become...

Investigation of the storage stability of pesticides (Project)
The storage stability of standard solutions that are used for quantification of pesticide residues is an important precondition for reliable data. Only limited data about the storage stability are available. Furthermore, the replacement of standard substances depending on the guarantee period given by the producer is an relevant expense factor. The storage stability of stock solutions should be...

Application of 2-DE-based proteomics for biomarker detection in human plasma (Project)
The application of methods of molecular toxicology is increasingly discussed also in the field of regulatory toxicology. A major issue is the question, wether these biochemical methods can be used to supplement conventional endpoints of health related toxicology. Mostly due to high costs, the use of methods of molececular toxicology (‘omics‘) is mainly restricted to pharmaceutical or industrial...

Influence of different extraction procedures on the recovery of pesticide residues analysed by liquid chromatographic methods (Project)
Comparison of 3 different methods of analysis, which are proposed by Sweden, the US and Germany, for simultaneous determination of pesticide residues. Discussion of the question which of these methods should be officially accepted as standard for the registration of pesticides.

FOR 536 P3: Mid term effects of grazing intensity on yield formation and forage quality in grassland ecosystems in Inner Mongolia with special reference to water supply (Project)
The objective for the second phase of the project is (1) to ensure the identification of plant related indicators after two years utilization, which can be used as tools to understand the dynamics of degradation and (2) to calibrate yield- and herbagequality- models. The experimental design will be extended in order to analyze the effect of sufficient soil moisture conditions (irrigation...
