In the waste treatment sector, various processes constitute sources of aerosols, such as activities on composting and wastewater treatment plants, spreading of organic waste on soil, or sprinkler irrigation of treated wastewater. We study bioaerosols by

  • characterizing the microbial diversity, the fate and dispersal of microorganisms after aerosolisation,
  • identifying the main drivers of aerosolization,
  • developing specific indicators and methodologies to measure the area impacted by the emission of bioaerosols.
