Biological particles play crucial role in Arctic cloud ice formation

An international team of scientists from Sweden, Norway, Japan, and Switzerland, has presented research findings that reveal a crucial role of biological particles, including pollen, spores, and bacteria, in the formation of ice within Arctic clouds. These findings, published in Nature Communications, have far-reaching implications for climate science and our understanding of the rapidly changing Arctic climate.

The smell of the sea – a key to understanding climate change?

How does the smell of the sea impact the world’s climate? This question lies at the heart of the Cyano-VOC research project. Within this endeavour, aerosol chemists collaborate with microbiologists to investigate the volatile organic compounds emitted by cyanobacteria and other plankton residing along the coastlines of the Baltic Sea.

Important insights on black carbon in Arctic clouds

For the first time, researchers can show directly over the course of all seasons, how much black carbon can be found inside Arctic clouds. These insights are important to better understand how clouds and aerosol particles interact in the Arctic environment.

Rendezvous for icebreaker Oden at the Arctic Sea

When there is a will, there is a way, as the saying goes, was what researchers from Stockholm University who participate in the Arctic expedition ARTofMELT 2023 recently came to realize right at the start of the expedition on Monday May 8th.

ALARM Sounded: Novel Project Aims to Map Global Exposure to Airborne Contaminants

We made our way to Mariakliniken, a hospital situated in the heart of Stockholm, where we met up with Daniel Schlesinger, former PhD student at the Department of Environmental Science and current Air Quality Officer, Post-Doc Jean Froment, Stefano Papazian, Head of the National Facility for Exposomics at ScilifeLab, and Master’s student Foteini Raptopoulou. Our mission was to visit the air quality monitoring station of SLB-analys, a unit within the Environmental Administration in Stockholm City, on behalf of the East Sweden Air Quality Management Association (Östra Sveriges Luftvårdsförbund), perched on the rooftop of the building. After navigating a dimly lit corridor and ascending a metal staircase, we arrived at three mushroom-shaped passive samplers arranged in the form of a crown. Jean had inserted a single silicone foam-based disc into each of the sampler housings, designed to collect gases and particles from the air.

Persistent pollutants found in one of Earth’s deepest ocean trenches

Researchers have detected the environmental pollutant PCB in sediment samples taken at a depth of 8,000 meters in the Pacific Ocean. While organic carbon is degraded, persistent PCB accumulates in the deep sea.
