25th ETH-Conference on Combustion Generated Nanoparticles

Corona viruses have turned into persistent threats for our society. Once again, we have decided to organize the 25th ETH-Conference on Combustion Generated Nanoparticles as an online event under the auspice of the Swiss Chemical Society. It served as an interdisciplinary platform for expert discussions on all aspects of nanoparticles, freshly emitted from various sources, aged in ambient air, technical mitigation aspects, impact of particles on health, environment and climate and particle legislation. The conference brought together representatives from research, industry and legislation.

Conference Topics

  • Ambient air particles, secondary pollutants
  • Aircraft, marine and non-Road sources
  • Biomass-, biofuel and synfuel combustion
  • Brake- and tyre-wear, non-combustion emissions
  • Emission control of combustion engines
  • Emission upgrade and PTI for in-use vehicles
  • Environmental and health effects
  • Exhaust aftertreatment systems
  • Future legislation and enforcement
  • Impact on climate
  • Nanoparticle metrology and chemical characterization
  • Nanoparticle chemistry and toxicology
  • Occupational exposure and prevention

Focus Event: New Legislation to Guide the World

The World Health Organization air quality guidelines, European vehicle and engine legislation, national clean air acts, and periodic technical inspection (PTI) legislation have become key elements of international and national clean air policy. With no doubt, the implementation of catalytic converter technologies and better fuels, compatible with such technologies, were major steps to reduce emission of combustion enginges. 
The 2022 focus event will discuss the next legislative steps to take and the challenges to tackle with new fuels and new enginge and vehicle technologies, to further reduce the impact of air pollution on health and global warming.

Health Session

The health session will focus on the effects of aircraft-/airport and wood smoke/wildfire related emissions.
