Selektion von Pflanzen aus der Flora von Kazachstan zur Verringerung der Schwermetalltoxizität in Kazachstan

Description: Die Projektsziele sind: 1) Selektion von geeigneten Pflanzen (Hyperakkumulatoren) für die Phyotextraktion von Cu, Cd, Pb und Zn auf kontaminierten Standorten sowie von Pflanzen mit geringer Akkumulation von Schwermetallen zur Verwendung als Tierfutter. Die gewählten Pflanzen sollen unter den klimatischen Verhältnissen von Kazachstan gedeihen. 2) In einem Pilotversuch soll die Effektivität der Phytoremediation gezeigt werden und ihre Vorteile wie geringe Kosten und geringer technischer Aufwand unter den Bedingungen in Kazachstan demonstriert werden. 3) Die Mechanismen der Schwermetall-Mobilisierung, -Aufnahme und Translokation sollen anhand der gewählten Pflanzenarten demonstriert werden.

  Title: Selection of plant genotypes from Kazakhstan Flora contributing to alleviation of heavy metal hazard to health and ecosystem in Kazakhstan
  Description: The overall objective of this project is to identify and select plant species and genotypes with either high or low heavy metal accumulation capacity to improve human and animal health via reduction of heavy metal transfer into the food chain or phytoextraction of metal-polluted soils. The specific research objectives are: 1. To select the most suitable species for phytoextraction of Cu, Cd, Pb and Zn from polluted soils (hyperaccumulators) and species with low accumulation capacity for use as cattle forage under the climatic conditions in Kazakhstan. 2. To demonstrate that the method of phytoremediation of contaminated soils can be efficient, cost-effective and suitable for up scaling under the prevailing edaphic and climatic conditions in Kazakhstan. 3. To enhance our understanding of the mechanisms of uptake, transport and accumulation of Cu, Cd, Pb and Zn in the species selected. The working program comprises broad-scale screening for accumulator and non-accumulator plants among the native flora growing on metallioferous soils in Kazakhstan and analysis of grass species for their heavy metals concentrations in shoots and roots. Soil samples will be taken from the same area and also will be analysed on heavy metal content. Grass species with high and low content of heavy metals will be selected for experiments under controlled conditions. Seedlings of grass species of the family Gramineae, will be grown under controlled conditions in hydroponic solutions with different concentrations of heavy metals (Zn, Pb, Cd, Cu). Based on this screening, selected species will be planted on soils artificially contaminated by Pb, Cu, Cd, Zn in order to assess the impact of these metals on growth and production of roots and shoots biomass. Metal-tolerant species and genotypes with the ability to either exclude or (hyper)accumulate heavy metals in their shoots will be individuated and evaluated for their potential use in the production of forage and phytoremediation respectively.. The proposed research work is deemed to contribute substantially to the development of novel technologies for the phytoextraction of heavy metals from soils. The climatic and edaphic conditions in Kazakhstan are representative of other countries in the general region where metal-contaminated soils are a serious threat to human and environmental health. Phytoremediation technologies provide an inexpensive alternative to traditional engineering techniques to clean up metal-contaminated soils and minimise potential impacts on human health at heavily polluted sites. The proposed research will result in field demonstration of phytoextraction in Kazakhstan and initiate technology transfer. The utilisation of native plant species will provide the opportunity for local businesses to develop. usw. https://ufordat.uba.de/UFORDAT/pages/PublicRedirect.aspx?TYP=PR&DSNR=84674
