Jana Weiss
Environmental and analytical chemist


My current research interests are within the field of identification of emerging contaminants using suspect and non-target screening techniques, combining analytical chemistry with toxicological studies in effect-directed analysis, exposure pathways to both the biota and the environment, and environmental ethical questions which we are facing regarding our responsibilities towards future generation and the planet.


I am teaching in courses introducing environmental chemistry on different levels, such as master courses and for a more general public having an interest in the topic. I am supervising PhD students connected to the projects and work for a close collaboration between several Universities.

SUPFES: Substitution in Practice of Prioritized Fluorinated Chemicals to Eliminate Diffuse Sources


I finished my Ph.D. in environmental chemistry at MMK in Stockholm 2006, mainly focusing on analysis of organic environmental pollutants in a variety of matrices, e.g. blood, milk, food. My thesis was entitled "Human exposure to persistent organic pollutants: Illustrated by four case studies in Europe". Between 2007 and 2009 I had a first post doc position at the Institute for Environmental Studies (IVM) in Amsterdam. The work performed there was implementing the Effect-Directed Analysis (EDA) approach which combines fractionation techniques and bioassays to guide the identification of key toxicants. Much focus was set toward chemical identification strategies of unknown chemicals of concern. I also broadened my experience into toxicology and to use in vitro assays. In 2009 I worked for the Joint Research Centre (JRC) in Ispra, Italy for 2.5 years, at the Institute for Environmental and Sustainability (IES). There I gained insight and experience how to work for the European Commission and was involved in a project supporting the Stockholm Convention to facilitate the Global Monitoring of priority pollutants.  In October 2011 I went back to IVM as senior researcher where I was involved in national and international projects, e.g. PERFOOD (, PHARMAS ( and SUPFES (

Since 1 April 2016 I have a 60% position at IVM-SLU where I am involved in the coordination of the project APPLICERA, focusing on identification of key-soil quality indexes and soil functions for an improved contaminated soil remediation strategy. 

I have also 40% position at the Department for Environmental Science and Analytical Chemistry (ACES) at Stockholm University, where I co-cordinate the FORMAS supported project MiSSE (Mixture Assessment of EDCs), as well as teach at the Introduction course for Environmental Chemistry (IEC).
