Soon the common eiders will return from their winter quarters in Central Europe, but even then, large areas in the archipelago will be devoid of breeding common eiders. The mortality during the last years has been so high that the characteristic eider song no longer will be heard at many places. Photo: Lennart Balk

Thiamine deficiency in wild animals is a serious threat to biodiversity

The lack of thiamine in wild animals leads to reproductive disorders, declining populations, impaired health and behavioural changes. This is shown from studies at the Department of Environmental Sciences and Analytical Chemistry (ACES), which has been investigating the presence of thiamine deficiency since the 1990s. The research has been highlighted in the scientific journal Trends in Ecology & Evolution. In …

Environmental science at Stockholm University ranked 33 in the world

Ten subjects at Stockholm University are listed among the top 100 in the world in the “QS world university rankings by subject” for 2018. Environmental science is on place 33 in the influential ranking list. The subjects ranked among the top hundred worldwide were Linguistics (46), Environmental science (33), Geography (40), Anthropology (47), Social policy & Administration (24) and Sociology (45). …

To fly or not to fly – what should climate researchers do?

Can you keep on conducting research about climate change without flying? To encourage a change in travel habits among the research community, the Department of Environmental Sciences and Analytical Chemistry (ACES) has launched a project where employees document their own greenhouse gas emissions. The project started at the beginning of this year and is called ”Tracking Greenhouse Gas Emissions”. “It’s …

What role do ocean margins play in the global carbon cycle?

By using the radiocarbon dating of land-plant molecules as a clock, an international research team led from the Department of Environmental Science and Analytical Chemistry at Stockholm University, has for the first time been able to assess the timescale for transport of organic carbon released from land across coastal seas. The approach has pinpointed transport time across the Siberian Arctic …

Det finns plats för 24 studenter i det nya masterprogrammet i miljö- och hälsoskydd som startar hösten 2018. Foto: Eva Dalin

Uppdrag: Att utbilda nya miljö- och hälsoskyddsinspektörer

Minska gapet mellan universitet och samhälle. Få studenterna att sätta in miljökunskaperna i ett större sammanhang. Fokusera på lösningar och inte bara på problem. Det är några av målen när ACES startar ett nytt masterprogram i miljö- och hälsoskydd hösten 2018. – Vi har märkt att det finns en stor efterfrågan på utbildade miljö- och hälsoinspektörer ute bland kommunerna i …

Hazards of microplastic exposure to animals uncertain

Microplastic and natural particles affect animals in similar ways, which makes evaluating the hazards of microplastics difficult, shows a new study by researchers from ACES and AquaBiota Water Research. These findings imply that unless we identify how and why microplastics differ from natural particles in their interaction with animals, we cannot be certain of how harmful they are. The study …

Land use affects climate more than previously thought

Forestry and pasturage have a much greater impact on the climate than previously thought. The ability of forests to store carbon dioxide decreases when people use them or let animals out to graze in them, and this usually applies to forestry and not just deforestation. This is shown in a study published by ACES researchers and their colleagues in Vienna, …

Phase-out of perfluorinated substances in North America and Europe shows promise for reducing impact on health but not the environment

The concentrations of a number of perfluorinated substances are currently on the decrease in humans in North America and Europe. However, in the environment, the same substances show no change. A team of researchers at ACES, completed a systematic review of how the concentrations of perfluoroalkyl acids (PFAAs) have been affected in the environment and in humans since their phase-out …

New method promises to cut down animal testing in carcinogen studies

Researchers at ACES have developed a new method that can potentially reduce animal experiments used to evaluate the risk of carcinogenic chemicals. The new study was published in the journal Scientific Reports. Humans are exposed to chemicals, for instance via food and dust, that can be metabolized into carcinogenic compounds upon entering the body. These compounds, even at very low …

Assistant Professor Claudia Mohr, ACES

Claudia Mohr is one of Wallenberg Academy Fellows 2017

Assistant Professor Claudia Mohr is one of the Wallenberg Academy Fellows 2017. Claudia, previously at the Karlsruhe Institute of Technology in Germany, joined ACES in May 2017. Emissions from vehicles, air travel and industry affect the formation of clouds in the atmosphere. Claudia will conduct detailed studies of how water vapor condenses around aerosol particles or airborne particles, to better …

ACES researcher secures major grant for tackling uncertainties in climate change research

ACES professor Örjan Gustafsson received 50 million SEK (€5 million) from the Swedish Research Council for a ten-year research project to tackle two major areas of uncertainty in climate research. The award is part of the Distinguished Professors Grant programme that aims to “create conditions for the most distinguished researchers to conduct long-term, innovative research with great potential to achieve …
