Lab analyses


Diatoms occur in diverse environments and respond quickly to changes in their environment. This makes them very suitable as indicators in assessments of water quality. Waardenburg Ecology analyzes diatoms and provides interpretation of the analysis results for ecological assessments, evaluations and impact studies.

Diatoms are a group of single-celled algae. Their structure is characterized by the glassy cell wall with silicon as the main component. The cell wall consists of two dishes that fit together like a box and a lid. The bowls are decorated with complicated or non-complicated structures that are species specific.

Environmental indicators

Factors such as temperature, salinity, nutrient richness and acidity influence the presence of diatom species. They respond quickly to changing environmental conditions. This makes them extremely suitable as indicators for the assessment of water quality within the Water Framework Directive (WFD). Diatoms are also relatively quick and easy to sample and can be easily identified to the species level.

Reconstructing landscapes

In archeology, diatoms are used to reconstruct information on the living environment and its changes over time. Diatoms have great added value for reconstructing the landscape, climate change and the living environment.
