It’s raining PFAS: “even in Antarctica and on the Tibetan plateau rainwater is unsafe to drink”

Per- and polyfluoroalkyl substances (PFAS) are man-made hazardous chemicals that are spread globally in the atmosphere and as a result they can be found in the rainwater and snow in even the most remote locations on Earth, shows a new study by researchers from Stockholm University and ETH Zurich published in Environmental Science & Technology. According to the authors, PFAS define …

New Master’s thesis shows cyclists’ harmful exposure to soot and nanoparticles during rush hour in Stockholm

In a new Master’s thesis, Laith Al-Qudah measured air quality during rush hour traffic along two popular bicycle routes in Stockholm for 2.5 months to understand how air pollution affects cyclists’ health. Laith Al-Qudah, a Master’s student in environment and health protection (MHS) at the Department of Environmental Science, recently presented his thesis, for which he measured air quality along …

“We do not have the time to waste!”

Science has an important role to play in the transition to a sustainable society. But more cooperation is needed and decision-makers must act faster on incorporating scientific evidence into meaningful policies. These were the key messages at the international sustainability conference hosted by the three main  universities in Stockholm and Stockholm Environment Institute. Watch Inger Andersen´s keynote address “The role …

Impressions from “eScience Tools in Climate Science: Linking Observations with Modelling 2021″

With the present-day remarkable computing speeds used in the Earth system models and super-sensitive measurement techniques for collecting observational data, it is the need of the hour to combine both these in a way that they complement and improve each other. For example, models could be constrained using the observations and experiments could be inspired from model simulations. This is …

Study uncovers double standard in regulation of antimicrobial substances

The regulation of antimicrobial substances differs when used in biocidal products compared to cosmetic products, shows a new study led by researchers at the Department of Environmental Science published recently in the journal Emerging Contaminants. Such inconsistencies could potentially endanger both the environment and human health. The researchers performed a systematic comparison using document analysis focusing on aims, scope, information …

When three’s not a crowd: vapour cocktail drives new particle formation in the upper troposphere

Newly-formed particles are important for cloud formation and are persistently observed over almost all regions of Earth’s upper troposphere. However, the vapours and mechanisms that drive the formation of these particles are not well understood. Now, a new study by an international team of researchers, including scientists from the Department of Environmental Science, published in Nature, presents a new mechanism …
