Erik Emke is a researcher on the Chemical Water Quality and Health team. Erik has 25 years of experience in the research, development and implementation of new analytical techniques for the detection of micropollutants in the water cycle. For the past 6 years, Erik mainly focused on the detection of nano particles such as fullerenes and Opium Law substances such as amphetamine and cocaine. In collaboration with a European consortium, Erik took stock of the use of these substances in populations for the Opium Law substances. He has an active role in harmonising the methods used. Erik specialises in analytical techniques, method development, sewage-based epidemiology, drugs, chemical water quality, monitoring and identification of unknown components.
