PhD student in analytical chemistry and environmental chemistry (Sweden)

The department has about 220 employees of which about 60 PhD students. Research study programs are offered in applied environmental science, analytical chemistry and environmental chemistry and courses are given in environmental science and analytical chemistry.

Chlorinated paraffins is a group of substances that are prohibited in Europe since they are harmful to aquatic organisms and very persistent. As a consequence, the production and use of short-chained chlorinated paraffins have decreased in Europe during the last decade. At the same time the production has increased significantly in China, which means that these substances may still enter the European market via consumer products. Chlorinated paraffins have chemical properties that make them difficult to analyze in environmental samples and test in aquatic ecotoxicity systems. As a consequence, there is a lack of reliable data on their presence and effects in the environment.

The primary aim of this PhD project is to generate reliable ecotoxicity data for short- and medium chained chlorinated paraffins. This will be achieved by the application of a novel exposure system for testing of hydrophobic substances, which is based on passive dosing. Another aim with the project is to improve the effect characterization of these substances by toxicokinetic modelling in aquatic test animals.

Qualification requirements

To be accepted to the research study program in applied environmental science, the applicant must have a university degree at the advanced level (e.g. Masters) or at least 240 hp/HEC, of which at least 60 hp/HEC at the advanced level. At least 45 of the credits at the advanced level must be in one of the natural sciences (Biology, Chemistry, Earth Sciences, Physics, or Meteorology) including a 30 hp/HEC thesis project.

The applicant should also have 30 hp/HEC in other natural science subjects different from the major. The academic requirements may be considered to be fulfilled if the applicant has acquired equivalent knowledge some other way.

Only a person who will be or has already been admitted to a third-cycle programme may be appointed to a doctoral studentship. The primary assessment criteria in appointing a doctoral student should be the capacity to benefit from the training.

Since the project covers both analytical environmental chemistry and ecotoxicology, combined competence and experience from both scientific disciplines is meriting.
