Post doc: Analysis of challenging microplastics in environmental samples, Department of Marine Sciences, University of Gothenburg, Sweden

Microplastics (MP) is a classification of microscopic polymer based particulate pollutants. Their origin may be from primary plastic particles from consumer products, or it may be fragment from weathered packaging or synthetic fibres from textiles. MP is found in aquatic systems as natural waters, sediment and biota. Since this is considered to be a potential environmental risk, it would be of great importance to be able to sample, and analyse this new form of pollution. This is important both for research needs but also for environmental monitoring since new sampling, sample preparation and analysis methods need to be developed and standardized.

Project description

The position will contribute to one or several ongoing research projects and government agency assignments, that aims to develop and apply advanced microscopy based analysis methods with spectroscopic identification of particles, with special focus on complex compositions like care tire wear particles or paint particles. It will deal about sediment samples and environmental water.

The work package where the successful candidate may participate, has an experimental focus including field sampling of water and sediment and analysis of specific NP with the analytical techniques listed below. Further experimental work, with model NP and simulated in situ conditions in the lab, will investigate how different parameters influence aggregation and sedimentation. Mainly, the effect of different quality and quantity if natural dissolved organic carbon affect these processes. To follow the interaction between NP and organic substances, the new technique of correlative SEM and Raman will be utilized. To enable selective detection and following of model NP in natural samples, single particle ICPMS and Nanoparticle Tracking Analysis can be used and complemented with SEM.

Qualifications

Requirements

We are looking for a candidate that is used to work independently and is driven.

We believe that a suitable background is a PhD within spectroscopy, analytical chemistry, chemical physics, physical chemistry or similar subjects, but previous experiences of the relevant spectroscopic and/or microscopy methods, together with some experience of aquatic environmental systems or processes is a prerequisite. Experience of one or more of the following methods is judged to be a necessary qualification: scanning electron microscopy, Raman spectral microscopy, FTIR, or NIR hyperspectral imaging.

Additional merits

Specific experience of analysis of especially challenging particles as tyre wear particles or paint particles is an advantage. Other useful experiences could include light scattering techniques or laboratory work on how NP behave in natural environments. Documented skills about sample preparation and sample processing for the techniques listed above is also relevant, as to some extent field work experience. Finally, extensive experience of programming in e.g. Matlab, Python or LabView could also be an important strength.

Personal qualifications

Good communication skills (both written and oral) in English is essential. Documented research and scientific writing ability (e.g. full text of at least three published scientific papers as first author) must be attached to the application.

Employment and location

The duration of employment is two years full time with start as soon as possible.

The position is based at the Department of Marine Sciences at the Sven Lovén Research Center Kristineberg, University of Gothenburg, Sweden.

To apply, please send CV, a three pages personal letter including a description of qualifications, including a detailed description of previous work relevant for the position, copy of PhD diploma, and a selection of published papers. The application and questions regarding the position should be sent to Professor Martin Hassellöv, martin.hassellov@marine.gu.se .

A certified to be true copy of the university’s diploma will be required.
