The Particle trap

How particle filters foil reduction strategies for nitrogen dioxide and ozone


A car releases different types of pollutants to the air. It is not easy to find technical solutions to reduce all of them in parallel.

UQ 3

May 2007







Part A: Ozone trends - Basic information on tropospheric ozone in Europe from the ACCENT project [ more ]
Part B: Increasing NO2 in cities - The influence of cars with particle filters on nitrogen dioxide concentrations [ more ]


Particle filters - Filtering particles from diesel cars and keeping other emissions low in parallel is a challenge. We briefly explain emission types and present technologies. [ more ]



Questions and investigations on traffic and pollutants

Part A: Traffic analysis - Suggestions for an analysis of traffic and air pollutant concentrations in your region [ more ]
Part B: Daily patterns - How do concentrations of nitrogen oxides and ozone change over the day depending on the location (city, suburbs, countryside). We present and analyse data. [ more ]
Part C: Questions - What did you learn? Try to answer some questions! [ more ]
