New methods to detect environmental pollutants

How can we improve the risk assessment of PAHs, a group of chemicals known to be potentially hazardous to human health? In a recently defended doctoral thesis, Hwanmi Lim at the Department of Environmental Science and Analytical Chemistry (ACES) presents new methods to obtain more accurate data on PAH exposure as well as the possibilities of using these data in …

The mortality among common eiders along the Swedish coast has been very high during the last years due to the lack of thiamine. This is shown from studies at the Department of Environmental Sciences and Analytical Chemistry (ACES). Photo: Lennart Balk

Increased attention on thiamine deficiency

At the end of September, the Norwegian public service channel NRK reported about the likely connection between thiamine deficiency and mass death of seabirds. Now the scientific journal Proceedings of the National Academy of Sciences of the United States of America (PNAS) draws attention to ACES research in the field. The Norwegian public service channel NRK reported that the population …

The thesis focuses on the implementation of the European Chemicals legislation REACH that came into force in 2007. Illustration by Linda Armyr

How transparent is REACH?

Concerns that previous European legislations were not providing adequate protection from chemical risks resulted in the new chemicals legislation REACH in 2007. In a recently defended doctoral thesis, Ellen Ingre-Khans at the Department of Environmental Science and Analytical Chemistry (ACES), shows that the legislation is not transparent enough in part due to the protection of confidential business information. Chemicals can …

Cloudcatcher – atmospheric research on Svalbard

Cloudcatcher. That’s the name of a new film that describes the atmospheric research done by scientists from the Department of Environmental Science and Analytical Chemistry (ACES) in Svalbard. The film is made by Melissa Gomis and Dämien Bolinius, former PhD students. “I wanted to raise awareness about climate change by showing a location where the impacts are clearly visible; the …

How much mercury is transported in aquatic food webs?

Sampling under windy conditions in Stockholm Archipelago and trying out different equipment to collect biota, sediments and waters from four lakes in Tyresta National Park. The focus for the students taking part in a master program in Environmental Science is to investigate how much mercury is transported in aquatic food webs. A new academic year has just begun and the …

Ny kurs i miljölagstiftning i vår

Hur arbetar man med miljölagstiftning och fysisk planering i en kommun? Går det att räkna ut trafikflödet på E4:an? Under våren 2019 genomför Institutionen för miljövetenskap och analytisk kemi (ACES) flera nya kurser, bland annat i miljölagstiftning och systemdynamik. Sista ansökningsdag är 15 oktober. – Både kursen i miljölagstiftning och kursen i systemdynamik passar studenter på masternivå. De ger redskap …

Understanding the details of aerosol formation is a key question for designing climate change and air pollution mitigation strategies. Photo: Jonas Witt/Flickr

A new step forward in understanding atmospheric aerosols

Atmospheric aerosols are tiny airborne particles that play an important role in Earth’s climate system. In addition, aerosols are a major component of air quality. In a new study published in Scientific Reports and led by researchers at ACES, a new method is presented for obtaining new information related to atmospheric particle formation from vapors. The information is needed for understanding …

The best way to measure air pollution

How much nitrogen oxide or asphalt particles are there in the air at a certain location in Trelleborg, Sundsvall or Stockholm? This is something that is recorded by different measurement stations located in urban environments around Sweden. But is the measurement station located in the right place along the street? Are the instruments approved? Researchers at ACES make sure that …

How essential are highly fluorinated chemicals in textiles? The statement aims to contribute for better collaboration between the scientists studying the compounds and the regulators tasked with assessing them to protect public health and the environment. Photo: Nick Cross,

International statement for actions on highly fluorinated chemicals

A group of more than 30 academic and government scientists, as well as regulators from various regulatory agencies across the globe have jointly outlined a set of needs, goals, and actions to help assess and manage per- and polyfluoroalkyl substances (PFASs) in the future. Professor Ian Cousins at the Department of Environmental Science and Analytical Chemistry (ACES) is a co-author …

Research about paternal epigenetic inheritance receives ERC Starting Grant

Three researchers at Stockholm University, including Oskar Karlsson at ACES, receive the prestigious Starting Grant from the European Research Council, ERC. Project funding amounts to up to 1.5 million euros each. The European Research Council allocates different types of funding and the purpose of the ERC Starting Grant is to encourage talented young research leaders in Europe to become independent …

Final conference on chemicals in dust indoors

Should we be more concerned about how we are exposed to chemicals indoors? A conference at the end of August summarizes several years of research on how we are exposed to hormone disrupting chemicals collected in the dust of our homes. “To sum up, one can say that our two main objectives have been to investigate whether dust is a …

What causes the poor health of perch in the Baltic Sea?

Why does the amount of perch decrease in the Baltic Sea? Could it be because of compounds naturally produced by algae and cyanobacteria? Could it also explain the poor health of several other species in the Baltic Sea? That is something researchers at ACES are trying to find out during the summer. A porch on Nämdö is used as a …
