Annual report 2017




Welcome to the Annual Report 2017 for the Mistra Environmental Nanosafety (MEN) program. This year we are publishing the annual report electronically, here on our consortium website, instead of in printed format. We hope that you can navigate through these pages and find the information you are interested in as easily as you would in a printed booklet. Please feel free to contact us if you have any questions. You can find our contact information at the bottom of this web page. The Mistra Environmental Nanosafety program partners include Chalmers University of Technology, University of Gothenburg, Lund University, KTH Royal Institute of Technology, Karolinska Institutet, and AkzoNobel.

Together we aim to develop generic methods and models that will provide a basis for risk assessments needed to promote environmentally safe development of nanotechnology in the future. The research program is organized into five work packages and designed around specific case studies, chosen due to their particular relevance to Swedish industry. Results from Case Study 1: Emission of nanoparticles from studded snow tires to road runoff water, with focus on tungsten carbide, tungsten carbide cobalt, and other related metallic nanoparticles, and Case Study 2: Systematic studies of commercially relevant nanoparticles, with focus on silica nanoparticles, are presented in this annual report. This report also provides an overview of the Mistra Environmental Nanosafety program and highlights our activities and results obtained during 2017. Some of the research results described in this annual report include results from a large questionnaire probing perceived risks and benefits, as well as risk regulation and risk management, of nanotechnology and nanomaterials. The questionaire was answered by Swedish experts in companies working with nanotechnology, trade associations, research institutes, government authorities and NGOs.

We also report on the detection of tungsten carbide nanoparticles in creeks leading to the Göta älv river near or away from the center of Gothenburg during winter versus summer months; results on the dissolution, aggregation and adsorption of natural organic matter (NOM) to tungsten carbide and tungsten carbide cobalt nanoparticles in surface water; the short term versus long term uptake and toxicity of tungsten carbide and tungsten carbide cobalt nanoparticles in aquatic organisms – a benthic isopod and zooplankton – and the effect of a pre-formed ”eco-corona” molecular coating on the dissolution, aggregation and toxicity of these nanoparticles. Partners in the program succeeded in generating and distributing traceable silica nanoparticles for use in our various model systems; characterizing the molecular coronas (proteins, NOMs) formed on silica nanoparticles and the resulting particle aggregation behavior using traditional as well as a newly developed detection methods; and screening of the toxicity of a library of silica particles in aquatic organisms at various levels up the food chain, including human immune cells.

On the program management side, last year we enlarged our management group to include Vice Program Manager Sverker Molander, Environmental Systems Analysis, Chalmers, as well as Project Manager Erik Nilebäck from Chalmers Industriteknik. Anna Wallin Adersjö from Gothenburg Centre for Sustainable Development became our new Communications Officer in August. Click on the pictures and topics below to find more details on our activities and outcomes from 2017, as well as information about the scientific program and consortium members. We are glad that you want to learn more about our research. And don't hesitate to contact us if you want more information.
