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 …

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, Flickr.com/cc

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 how man’s life experiences may impact the health of his unborn children and grandchildren receives funding. Foto: Kevin Conor Keller Flickr/cc

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 …

Research expedition to the Arctic sets sail

The 1st of August sees the start of the Swedish-American research expedition Arctic Ocean 2018. Forty researchers from all over the world will be based and work on board the Swedish icebreaker Oden whilst moored to a moving ice floe. The overall theme of the expedition is the formation of clouds. Clouds play a very important role in the Arctic …

The main route of exposure to halogenated flame retardants for adults in the study is the consumption of contaminated food, cooking utensils, dust particles adhering to the food as well as migration from food packaging. Photo: Flickr cc

Diet is the main source of halogenated flame retardants

Dietary intake is the main route of exposure to halogenated flame retardants for a studied Norwegian group. That is one result from a research project that Joo Hui Tay, PhD at the Department of Environmental Science and Analytical Chemistry (ACES), Stockholm University, presents in a recently defended doctoral thesis. Flame retardants are chemicals added to various consumer products, such as …

The highest levels of the carcinogenic chemicals have been measured in a large number of foods, especially in heat-treated cooking oils. Photo: Shereen M/Flickr cc

A new approach can shorten the time to assess cancer risk for chemicals

Chemicals in refined cooking oils like palm oil can cause cancer, shown in several studies. In a new doctoral thesis, Jenny Aasa at the Department of Environmental Sciences and Analytical Chemistry (ACES), Stockholm University, has studied two such chemicals, and by using a new approach she hopes to improve and shorten the time for risk assessment. The chemicals that Jenny …

Plastic debris accumulates in the environment and lately much attention has been drawn to the pollution in the world’s oceans. Photo: Berit Gewert

Plastic degrading in the oceans release chemicals into the water

Floating plastic debris in the marine environment can be degraded by reactions initiated by UV-radiation, hydrolysis, and microorganisms. Degradation of plastics releases chemical compounds to the water. The compounds and their amounts are dependent on the plastic polymer and the weathering condition of the plastic. These are the key findings in a recently defended doctoral thesis by Berit Gewert at …

Johan Gustafsson receives grant for higher studies abroad

Johan Gustafsson, PhD student at the Department of Environmental Science and Analytical Chemistry (ACES) has received 100 000 SEK from Gålöstiftelsen, a Swedish foundation that allocates student grants for, among other things, higher studies abroad. Johan Gustafsson is doing research about the deteriorating health status in Baltic Sea wildlife related to a disturbed energy metabolism. The funding from Gålöstiftelsen will fund …
