Which particulate air pollution poses the greatest health risk?

Media Releases Energy and Climate Health Innovation Environment

The composition of particulate matter can influence its harmfulness to human health just as much as the amount, PSI researchers show in a newly published study. Experiments and computational modelling showed that in Europe high concentrations of particulate matter harmful to human health occur mainly in metropolitan areas.

First-time direct proof of chemical reactions in particulates

Media Releases Environment Energy and Climate

Researchers at the Paul Scherrer Institute PSI have developed a new method to analyse particulate matter more precisely than ever before. With its help, they disproved an established doctrine: that molecules in aerosols undergo no further chemical transformations because they are enclosed in other particulate matter.

Why the Little Ice Age ended in the middle of the 19th century

Media Releases Energy and Climate Environment

In the first half of the 19th century, a series of large volcanic eruptions in the tropics led to a temporary global cooling of Earth's climate. That Alpine glaciers grew and subsequently receded again during the final phase of the so-called Little Ice Age was due to a natural process. This has now been proven by PSI researchers on the basis of ice cores.

Atmosphere in X-ray light

Media Releases Energy and Climate Research Using Synchrotron Light Environment

PSI researchers have developed an experimental chamber in which they can recreate atmospheric processes and probe them with unprecedented precision, using X-ray light from the Swiss Light Source SLS. In the initial experiments, they have studied the production of bromine, which plays an essential role in the decomposition of ozone in the lower layers of the atmosphere. In the future, the new experiment chamber will also be available for use by researchers from other scientific fields.
