Project Description

This PhD project, within the Unit for Atmospheric Science, will investigate the chemical composition and toxicity of airborne particles from quartz-containing materials such as:

• Artificial stone
• Concrete
• Brick
• Natural stone
• Sand

Key aspects of the research:

• Quartz dust exposure affects over 200,000 employees in Sweden, particularly during processing of high-quartz materials.
• The project aims to identify which particle properties cause harmful effects using a human Air–Liquid Interface (ALI) lung cell model.
• Particles will be tested both fresh and aged, directly or via collected samples in submerged cell cultures.
• Toxicity endpoints include cell death, inflammation, oxidative stress, and DNA damage.
• Particle chemical reactivity will be assessed using advanced analytical methods.
• Collaboration with other universities (e.g., Uppsala University) will involve research visits.
