Professor Conny Östman

Personal

I took my PhD in Analytical Chemistry in 1987 and started working as researcher at the Swedish National Institute of Occupational Health in 1988. I was appointed associate professor in Environmental Chemistry in 1994. In 1997 I started working at the Department of Analytical Chemistry at Stocholm University as Researcher and Senior Lecturer. In 2015 I was appointed Professor in Analytical Chemistry and started at the new Department of Environmental Science and Analytical Chemistry. I have supervised seven and am presently supervising two PhD students.

My research work includes development and application of analytical methods including sampling, extraction, clean-up, and methods for separation and identification of chemical compounds using GC, HPLC, GC-MS, GC-MS/MS, LC-MS and LC-MS/MS techniques.

During the years my field of research has included areas such as indoor air pollutants (including flame retardants, plasticizers etc), emission of chemicals from computers and electronic equipment, polychlorinated biphenyls (PCBs) in human blood, polybrominated diphenyl ethers (PBDEs) in various matrices, polycyclic aromatic hydrocarbons/compounds (PAH/PAC) in air, oil, soil, bitumen, curing smoke, stack gases etc, Shpolskii low temperature fluorescence, development of personal sampling equipment, development of hyphenated analytical techniques (coupled LC/GC and LC/GC/MS), etc.

Today my field of research is focused on textiles as a route to chemical exposure.

Research

Chemicals in Textiles

Today my research is focused on chemicals in textiles. It involves non-targeted analysis of chemicals in textile materials, development of analytical methods for chemicals in textiles, studies of textile to skin transfer of chemicals by in vitro studies using artificial, skin mimicing membranes and development of fast screening methods for chemicals in textiles.
Clothing textiles is a source to human exposure to chemicals that is very little investigated. In this project we have taken an exploratory chemical analysis approach to investigate what chemicals are present in clothing sold the open market. Our screening has demonstrated the presence of hundreds of chemicals in garments obtained from the retail market.

At present we have developed target analytical methods for selective analysis of four groups of compounds found to be present in several of the investigated garments: quinolines, nitroanilines, benzothiazoles and benzotriazoles. We have also demonstrated that these compounds can released from the textiles during laundry and that they are released to the household wastewater.

The project has received a grant of 3 million SEK from the Swedish Research Council FORMAS for the years 2018-2020.

Teaching

I am teaching chromatography on basic and advanced level courses in Analytical Chemistry. I am Course Director and Examiner for the advanced level course Advanced Separation Methods, and Course Director and Examiner for the departments Degree Projects in Analytical Chemistry at basic and advanced level. I am also Programme Director for the departments Master Programme in Analytical Chemistry.
