Prof. Dr. Bart Koelmans is an environmental chemist and ecotoxicologist by training, heading the Aquatic Ecology and Water Quality Department at Wageningen University (The Netherlands). In the field of plastic research, his group aims to bridge the gap between conceptual and empirical approaches, in order to obtain a mechanistic understanding of the risks of microplastic for human health and the environment. Bart is a global highly cited researcher, advises international organisations like the World Health Organization and the UN (GESAMP expert groups), and led international working groups about risks of plastic pollution, such as the SAPEA expert group on Microplastics in Nature and Society.

Tim van Emmerik, PhD   
Hydrology and Quantitative Water Management, Wageningen University, Wageningen, The Netherlands
New Content ItemTim van Emmerik is an experimental hydrologist and aims to provide accurate and reliable data to solve societal water-related challenges. As plastic pollution of aquatic ecosystems is an emerging hazard, his ambition is to develop river plastic monitoring techniques that can be applied to (1) quantify plastic pollution any river around the world, and (2) optimize plastic pollution prevention and reduction strategies. A holistic approach is key, as rivers, societies and their interconnections vary greatly around the world. River plastic pollution is a complex problem that crosses spatiotemporal scales. Tim’s research focuses on developing methods that can be applied at both the field scale (single rivers) and global scale (continental assessments).

Denise M. Mitrano is an assistant professor at ETH Zurich in the Environmental Systems Science Department. As an environmental analytical chemist, her research focuses on the distribution and impacts of anthropogenic materials in technical and environmental systems. She is particularly interested in developing analytical tools and processes to mechanistically understand the fate, transport and biological interactions of particles, such as metal colloids, engineered nanomaterials and nano- and microplastics. In this context, her research group uses these results to assess risks of anthropogenic materials. An interest in a “safer by design” approach for both nanomaterials and plastics continues by working on the boundaries of environmental science, materials science and policy to promote sustainability and environmental health and safety of new materials.

Martin Thiel, PhD
Facultad Ciencias del Mar, Universidad Catolica del Norte,  Antofagasta, Chile
New Content Item     

A marine biologist with strong interest in in the behavioral ecology of marine invertebrates and the functioning of marine communities. Together with his students he has studied the reproductive biology of a variety of free-living and symbiotic crustaceans, and the community dynamics in biotic habitats (mussel and ascidian beds, algal turfs and kelp forests). One key research topic is rafting dispersal (mostly on floating kelps). The large amounts of floating marine litter encountered during their research and the complete lack of scientific information about marine litter from the SE Pacific led him and his team to include this topic in their investigations. In 2007 they founded the citizen science program "Cientificos de la Basura" (Litter Scientists), which has since been expanded to other countries along the East Pacific ( This initiative is a research collaboration between scientists and schoolchildren with the goal of characterizing and understanding the problem of marine litter (see also
