Postdoctoral Fellow in Environmental Organic Chemistry

Ref. No. SU FV-0363-17

at the Department of Environmental Science and Analytical Chemistry. Closing date: 31 March 2017.

The Department of Environmental Science and Analytical Chemistry (ACES) employs about 220 employees: researchers, postdoctoral fellows, doctoral students and technical/administrative support staff. The sources and fate of environmental contaminants is one of the research foci, and the department maintains state of the art instrumentation for ultra/trace analysis of organic chemicals in complex matrices.

Project description

Oceans are known to be recipients of many pollutants, but also act as secondary sources to the atmosphere. While ocean-air exchange of gas-phase pollutants has been well-studied, little work has focused on sea-spray associated transport of pollutants. Therefore, oceans are often incorrectly assumed to be irreversible sinks for non-volatile pollutants. Sea-spray aerosols are formed at the water surface through the action of bubble bursting and have been shown to be enriched in organic matter. They also exist in the size range that facilitates long-range transport in the atmosphere. The overall goal is to test the hypothesis that surface active substances can be efficiently transferred across the water–air interface during sea-spray aerosol formation and that the efficiency of transfer is controlled by the substance’s physical-chemical properties as well as the water chemistry and climatic conditions. Recent development of experimental methods at Stockholm University now provides a unique possibility to examine in detail the process of sea-spray mediated transport of pollutants. We will take advantage of this possibility and study water–air transport for a range of pollutants at concentrations and conditions relevant for real ocean environments. Based on the experiments, a theory of the process will be developed and evaluated in the field. Furthermore, we will apply the theory in a transport model to examine pollutant water–air transfer via aerosol particles on a global scale. The project is funded by a grant from the Swedish Research Council (Vetenskapsrådet).

The successful candidate would work within a small team focusing on this research topic comprising several senior scientists and one PhD student. Postdoctoral Fellow will also be a member of a research group in the Contaminant Chemistry Unit led by Ian Cousins. The project is, however, an inter-unit collaboration in our department between the Contaminant Chemistry Unit and the Atmospheric Science Unit.

Main responsibilities

The postdoctoral fellow will primarily plan and conduct experimental research in the laboratory and field to investigate the sea-spray associated transport of pollutants. The experimental research will involve analysis of pollutants using advanced instrumental methods.

Qualification requirements

Postdoctoral positions are appointed primarily for purposes of research. Applicants are expected to hold a Swedish doctoral degree or an equivalent degree from another country.

Assessment criteria

The degree should have been completed no more than three years before the deadline for applications. An older degree may be acceptable under special circumstances, which may involve sick leave, parental leave, clinical attachment, elected positions in trade unions, or similar.

The primary assessment criterion is scientific excellence in environmental organic chemistry. Competence in running UPLC-MS instruments is also a strong merit. A good command of English is required.

Terms of employment

The position involves full-time employment for a maximum of two years, with the possibility of extension under special circumstances. Start date 1 July 2017 or as per agreement.

Stockholm University strives to be a workplace free from discrimination and with equal opportunities for all.
