Particles in the Atmosphere

What is floating in the air?

Urbino Questions

UQ 1

November / December 2006

Chemie

Chemistry / Physics

    
The pollution of our air with ozone, other gases and particles has an impact on our life. The research of ACCENT is coordinated in the little Italian town of Urbino. Here, scientists try to find answers to the topical questions of politicians and decision makers.

Urbino Questions

Introduction

Particles are suspended everywhere in the air. We also call them aerosols. Their availability is of essential importance for our environment, health and the climate system. Over several editions on the "Urbino Questions" we are going to discuss the properties of particles. [ more
