Pflanzenpathologie und Pflanzenschutz

Hon. Prof. Dr. Lennart Weltje

Positionen

  • Leitender regulatorischer Ökotoxikologe der "Global Ecotoxicology Group" der BASF-Abteilung "Agricultural Solutions", Limburgerhof, Deutschland
  • Honorarprofessor an der Fakultät für Agrarwissenschaften der Georg-August-Universität Göttingen

Forschung

Zu den Forschungsinteressen von Professor Weltje gehört die ökotoxikologische Risikobewertung von Pflanzenschutzmitteln und Bioziden in der (aquatischen) Umwelt. Sein besonderes Interesse gilt Fischen, Wirbellosen und Amphibien. Ein weiterer Schwerpunkt liegt auf endokrinen Störungen in diesen taxonomischen Gruppen. In der Vergangenheit beschäftigte er sich mit der Ökotoxikologie von (Schwer-)Metallgemischen im Boden. Seine Doktorarbeit befasste sich mit aquatischer Ökotoxikologie und Umweltchemie von Lanthaniden (REEs).

Curriculum vitae

  • Lennart Weltje is a senior regulatory ecotoxicologist at BASF Crop Protection in Limburgerhof, Germany. He holds a B.Sc. and M.Sc. in Biology from Utrecht University in The Netherlands, and a Ph.D. in Ecotoxicology and Environmental Chemistry from the Delft University of Technology in The Netherlands, where he was also trained as a Radiation Safety Officer.

    From 1993 to 1995, he was employed at the National Institute for Public Health and the Environment (RIVM, Bilthoven, The Netherlands) performing research on mixture toxicity of heavy metals and PAHs to soil invertebrates.
    In 2001, he received a 2-year EU Marie-Curie postdoc fellowship to do research on endocrine disruption in freshwater invertebrates at the International Graduate School (IHI) in Zittau, Germany.

    In 2004, he started working for BASF, where he is responsible for aquatic risk assessments of plant protection products. Lennart’s areas of expertise include endocrine disruption, mixture toxicity, amphibian toxicology, sediment and aquatic invertebrates.

    Lennart is a member of the endocrine disruption expert groups of CropLife Europe, ECETOC and the SETAC Advisory Group on Endocrine Disruptor Testing and Risk Assessment. For two years he represented industry in the ECHA Endocrine Disruption Expert Group. At OECD, he is a BIAC member of the ad hoc invertebrate expert group and was involved in toxicity test guideline development for duckweed, chironomids and freshwater snails. Since 2011 he is chairman of the annual Fresenius Conference on Endocrine Disruption. In 2011, he started lecturing Regulatory Ecotoxicology of Pesticides at the University of Göttingen in Germany, where he became an honorary professor in 2018.

    Lennart is a co-author of around 80 peer-reviewed papers (for his full publication list see: www.researchgate.net/profile/Lennart_Weltje).
