Particulate matter characterization in a steelworks using conventional sampling and innovative lidar observations

- The main input of particles within the steelworks originated from open sources.
- Stacks had a limited effect on the coarse particle concentrations.
- Fine particles were emitted mainly from stacks, fugitive emissions and open sources on site.
- Regional background provided high amount of fine aerosols to the steelworks.
- Lidars allowed to map aerosols in real time.
