Researcher, Environmental Microbiologist

Researcher, Environmental Microbiologist for global R&D Site in Deventer.


The production and widespread use of chemicals in different industrial and domestic applications lead to the introduction of these chemicals into nature through discharge of wastewater or by direct applications. Biodegradation is regarded as the most important process in reducing chemical concentrations in the environment. The fate of chemicals in the environment is assessed by performing biodegradation tests.

Part of Nouryon’s Expert Capability Group (ECG), the Environmental Chemistry laboratory is specialized in performing biodegradation tests according to international standard guidelines and under the Good Laboratory Practice (GLP) quality system. Our knowledge on environmental microbiology and microbial physiology ensures assessment of the biodegradability under optimal conditions. Results from biodegradation testing and research find use in substance profiling including classification and labelling, registrations, notifications, risk assessments and contribute to Safety Data Sheet (SDS) production.
