In the Helmholtz research program “Changing Earth – Sustaining our Future” of the Research Field Earth and Environment, seven Helmholtz Centers (AWI, FZJ, GEOMAR, GFZ, Hereon, KIT, UFZ) are collaborating to gather deep insights into the complex relationships between the processes that take place on our planet. They are pooling their competencies to research the natural foundations of life in a systemic approach, from the land surface to the oceans and to the Polar Regions. For only with sound knowledge of the Earth system, with innovative technologies and strategic approaches and recommendations for politics the path to a sustainable future is possible.
Within the framework of this program, the project “P-LEACH: Impacts on ecosystem functions and human health by environmental plastics and associated chemicals”, is one of four “innovation pool projects”. These serve to strengthen the cooperation between the centers, to promote innovative ideas of young scientists, and to provide flexibility in dealing with current, socially relevant themes.
The project P-LEACH which aims to study the effects of chemicals from globally increasing environmental plastic pollution on ecosystem functions and human health, invites applications for 2 positions as Post Doc (f/m/d).
Position 1: Analysis of micro- and plastics formed by environmental plastics
(Chemistry) (link)
Position 2: Physiology and metabolomics of bivalves (Biology)
Background and Tasks
Since the 1950’s the increasing production of plastics resulted in a progressive accumulation of plastic litter in the oceans with manifold consequences for marine life. Plastics impact ecosystems as a new habitat for colonization (“plastisphere”), and weathering leads to fragmentation towards micro and nano sized particles as well as leaching of chemicals, including harmful additives (e.g., plasticizers, bisphenols, metals). Such sized particles and plastic-associated chemicals have frequently been highlighted as (eco)toxicologically important compounds, but have not been adequately addressed. Our multidisciplinary consortium will jointly characterize these pollutants, identify harmful chemicals and investigate their synergistic impacts on ecosystem functions.
Studies investigating physiological impact of MP on bivalves so far ignored the potential risk of associated chemicals on animals’ health. Therefore, we aim to investigate and evaluate the effect of MP-associated leachates on bivalves with focus on immune system and energy metabolism by combining metabolomic, biochemical and physiological approaches. The comparative approach used in the project involves tissue analyses of marine bivalves that will be experimentally exposed (mesocosm data) and sampled from global hot spots (field data).
