About me


In my PhD project I am investigating our policies and praxis in dealing with contaminated sediments.

I investigate what we measure and how we integrate our results in risk assessments in Sweden today in relation to our environmental goals and current policies.

In providing a better understanding of how we should deal with our contaminated sediments I aim to contribute to more standardized risk assessments and a harmonized communication between the stakeholders working with contaminated sediments in Sweden.

The project is carried out together with my supervisors tech. dr Yvonne Ohlsson at the Swedish Geotechnical Institute, Dr. Anna Sobek at ACES, Stockholm University and Prof. Clare Bradshaw at DEEP, Stockholm University.



Communication is in my view imperative for all research. In 2018 I take care of the departments Instagram and Facebook accounts - find us at Deepsthlmuni.

Illustrations are key to communication and here you can read more about how I think we could improve our illustration skills in research.

Communication is about spreading the word. I have had the fortune to communicate my experiences when leading courses at the Swedish development agencies for students receiving stipends for research in development areas. Click here for more information in Swedish. 

You can also find me at LinkedIN


For several years I have been the main assisstant for our course in ecotoxicology, taking care of our students and the logstics. 

I have had the opportunity to teach mainly about Environmental Risk Assessment through lectures, group projects and seminars. I have also developed my own course module on scientific communication. My pedagogic approach has been well received by the students.

  • Assessing and managing multiple risks in a changing worldThe Roskilde recommendations

    2017. Henriette Selck (et al.). Environmental Toxicology and Chemistry 36 (1), 7-16


    Roskilde University (Denmark) hosted a November 2015 workshop, Environmental RiskAssessing and Managing Multiple Risks in a Changing World. This Focus article presents the consensus recommendations of 30 attendees from 9 countries regarding implementation of a common currency (ecosystem services) for holistic environmental risk assessment and management; improvements to risk assessment and management in a complex, human-modified, and changing world; appropriate development of protection goals in a 2-stage process; dealing with societal issues; risk-management information needs; conducting risk assessment of risk management; and development of adaptive and flexible regulatory systems. The authors encourage both cross-disciplinary and interdisciplinary approaches to address their 10 recommendations: 1) adopt ecosystem services as a common currency for risk assessment and management; 2) consider cumulative stressors (chemical and nonchemical) and determine which dominate to best manage and restore ecosystem services; 3) fully integrate risk managers and communities of interest into the risk-assessment process; 4) fully integrate risk assessors and communities of interest into the risk-management process; 5) consider socioeconomics and increased transparency in both risk assessment and risk management; 6) recognize the ethical rights of humans and ecosystems to an adequate level of protection; 7) determine relevant reference conditions and the proper ecological context for assessments in human-modified systems; 8) assess risks and benefits to humans and the ecosystem and consider unintended consequences of management actions; 9) avoid excessive conservatism or possible underprotection resulting from sole reliance on binary, numerical benchmarks; and 10) develop adaptive risk-management and regulatory goals based on ranges of uncertainty.

  • Toward a Conceptual Approach for Assessing Risks from Chemical Mixtures and Other Stressors to Coastal Ecosystem Services

    2017. Kristian Syberg (et al.). Integrated Environmental Assessment and Management 13 (2), 376-386


    Growth of human populations and increased human activity, particularly in coastal areas, increase pressure on coastal ecosystems and the ecosystem services (ES) they provide. As a means toward being able to assess the impact of multiple stressors on ES, in the present study we propose an 8-step conceptual approach for assessing effects of chemical mixtures and other stressors on ES in coastal areas: step A, identify the relevant problems and policy aims; step B, identify temporal and spatial boundaries; step C, identify relevant ES; step D, identify relevant stressors (e.g., chemicals); step E, translate impacts into ES units; step F, assess cumulative risk in ES units; step G, rank stressors based on their contribution to adverse effects on ES; and step H, implement regulation and management as appropriate and necessary. Two illustrative case studies (Swedish coastal waters and a coastal lagoon in Costa Rica) are provided; one focuses on chemicals that affect human food supply and the other addresses pesticide runoff and trade-offs among ES. The 2 cases are used to highlight challenges of such risk assessments, including use of standardized versus ES-relevant test species, data completeness, and trade-offs among ES. Lessons learned from the 2 case studies are discussed in relation to environmental risk assessment and management of chemical mixtures. Integr Environ Assess Manag 2017;13:376-386.
