Emissions of organic chemicals from technosphere articles – Conceptual modelling and quantification

Research project The aim of this project is to develop methodology to quantify the emissions of organic compounds from consumer products

This PhD project is part of a major research programme on Organic Chemicals Emitted from Technosphere Goods “ChEmiGoods” sponsored by the Swedish Environmental Protection Agency. The overall aim of the programme is to increase the scientific understanding of the magnitude of the problem regarding emissions from articles with the objective to support policy development in Sweden and Europe. In close collaboration and interaction with authorities and other stakeholders, the programme identifies technical, scientific and social aspects of concern contributing to the magnitude and perception of emissions of organic chemicals from articles as constituting a problem. This project develops an integrated approach to identification of substances and articles of concern, quantifies the emissions of organic compounds from articles and puts these in relation to other emissions. In other projects, Stakeholders' perceptions on the problem and behavioral responses to communication of chemical risks are studied, and problem reduction strategies, both by legislation and voluntary approaches, are analyzed. Finally roadmaps and indicators for policies and strategies towards "A Non-toxic environment" are outlined.

Project description

In this project we seek fundamental understanding of the processes underlying the emissions of organic compounds from materials and articles, by developing new conceptual models and compiling existing and generating new emission factors for combinations of substances, materials, and life cycle phases. For selected chemicals, detailed case studies will be made to further elaborate the understanding of the emission processes. A generic model for emissions of organic substances from articles will also be developed and implemented with the compiled emission factors. It will be used to predict emissions of organic compounds from materials during various segment of the life cycle of an article. The models will finally be used in combination with national statistics and surveys of article and waste flows in society (generated by other partners) and will provide an estimate of the national emission levels and how these can be expected to change over time.
