1. Collect size-fractionated PM from underground railway station.
2. Analyse chemical composition and morphology (Geochemistry Group).
3. Measure PM-mediated reactive oxygen generation.
4. Examine whether underground PM can elicit antioxidant and pro-inflammatory responses, or cause cell death, in airway epithelial cell cultures (Brooke Lab, Faculty of Medicine).
- If underground PM is found to be toxic, there may be implications for regular commuters and workers, especially those with pre-existing lung conditions e.g. asthma.
- Better understanding of the mechanisms of toxicity of PM may inform future improvements in material use and monitoring of at-risk groups.
- Understanding the effects of PM on the lungs will aid understanding of how PM pollution affects other organ systems e.g. cardiovascular system, which we hope to investigate in the future.
