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 …

“Important to identify the chemicals behind contact allergy”

Contact allergy is one of the major skin health problems in the Western world. In his thesis, Ahmed Ramzi at the Department of Environmental Science and Analytical Chemistry (ACES), shows the importance of developing analytical methods for the identification, measurement and detection of important molecules in contact allergy. He also hopes to increase the common awareness of the strong allergenic …

Christina Rudén, Professor of Regulatory Toxicology and Ecotoxicology at ACES, has been appointed the Government’s special investigator on how chemicals legislation could also include mixtures and grouping of chemicals. Photo: Annika Hallman

Mission: To manage the cocktail effect

What happens when we are exposed to many chemicals in a complex mix? Who is responsible for the mixture? And how does it affect people, animals and the environment? As the Swedish government’s special investigator, Christina Rudén, Professor of Regulatory Toxicology and Ecotoxicology at the Department of Environmental Sciences and Analytical Chemistry (ACES), Stockholm University, will propose strategies for taking …

In a role-playing exercise the students should act as representatives from different countries in a climate negotiation about how to live up to the Paris Agreement from 2015. Photo: Annika Hallman

Students negotiated about the climate

What is climate change and what can we do about it? That was the main question when the annual Climate Festival took place in Geohuset at Frescati in May. The festival is aimed primarily at young people in elementary school and high school and during three days they could meet climate researchers at Stockholm University to learn more about climate …

Atmospheric research at the top

A team of atmospheric scientists from the Department of Environmental Science and Analytical Chemistry (ACES), Stockholm University, is currently taking part in a two month project to measure the composition of the atmosphere at the highest atmospheric research station in the world. The station is situated in the Bolivian Andes at 5 240 meters above sea level. “We have assembled …

Two researchers at ACES appointed as Outstanding Reviewers

In the age of fake news the system with peer reviewing might be even more important, believe the researchers at ACES who are highlighted as “Outstanding Reviewers” for the scientific journal Environmental Science: Processes & Impacts in 2017. Professor Michael McLachlan and postdoc Dr Zhe Li, both at ACES, have been appointed as “Outstanding Reviewers” in a list with a …

Reduced levels of exhaust emissions from road traffic have resulted in a better air quality. The picture shows part of Södermalm, Stockholm. Photo: Astrid Vågen/Wikimedia Commons

Cleaner air has increased life expectancy by up to 1 year

The residents of Stockholm, Gothenburg and Malmö live one year longer today than 25 years ago. The reason is that the levels of air pollutants from road traffic have fallen. This is shown in a new study published in the discussion forum of the scientific journal Atmospheric Chemistry and Physics by researchers at the Department of Environmental Sciences and Analytical …

Four programmes at ACES in the autumn

In the autumn 2018 four programmes will be offered at the Department of Environmental Sciences and Analytical Chemistry (ACES). Deadline for application is the 16th of April. There will be three master programmes at the institution: Analytical Chemistry, Environmental Science and a completely new master programme in Swedish, Miljö- och hälsoskydd. In addition, a Kandidatprogram i miljövetenskap will start, this …
