The Department for Environmental Quality and Analysis is part of the TNO. Environmental and Geosciences is involved in analysing and assessing environmental impacts resulting from human activities, industrial processes and the use of products. The institute has an international reputation related to their role in determining the consequences of emissions of environment polluting substances on environmental quality, and also determines and controls the risks of catastrophes and continuous emissions. Within the field of air quality, the Department of Environmental Quality and Analysis is internationally renowned for modelling of air pollution dispersion and of exchange processes. The experimental department has a good reputation in monitoring pollutants such as particulate matter, nitrogen oxides, ammonia and pesticides. The Environment and Health department is well known for the URBIS model, which allows an integrated assessment of exposure to noise and air pollution in cities. The department of soil sciences is strongly involved in all aspects of soil pollution including the exposure related to contaminated sites. The institute collaborates very closely with local and regional authorities and provides support to the national government. TNO Environmental and Geosciences is strongly involved in several EU funded projects such as AIR4EU (coordinator) and AQUATERRA. Relevant expertise includes: monitoring of air quality from local to regional scale; modelling of air quality and multimedia modelling; emission assessment; assessment of health effects of noise; environmental policy; soil sciences.

Dr. Jan Duyzer is leader of the group carrying out the field studies. He is an atmospheric chemist with more than 20 years of experience, and has led several research projects, including joint EU projects in FP 3 and 4. He has relevant expertise in air pollution modelling and monitoring and exchange processes of compounds between environmental compartments. Recently he has been involved in projects under contract with the Dutch ministry of the environment and Dutch provinces. These projects were on human exposure related to pesticide use in greenhouses and on fields. He is also in charge of the monitoring networks of pesticides and ammonia. He is (co)author of over two hundred reports and papers, of which over forty have appeared in peer reviewed journals.

TNO is involved in: WP2.1 (Environmental monitoring), as WP leader); WP2.4 (Integrated monitoring); WP3.1 (Traffic); WP3.3 (Agriculture); WP5.2 (Internal training), WP6.1 (User consultation) and WP6.3 (External training).
