Standardisation of methods – basis for comparing results and quality control

Aim of the project was to standardise sampling and lab processing methods

For the following steps standardised procedure have been suggested:

• Sampling method

• Lab processing (subsampling, sorting)

• Identification

Different methods were tested according to their precision and costs.

Short descriptions of the methods are given on the pages “sampling”, “sorting” and “identification”.

Further information is provided by the final report of the project „Standardisation of sampling and data evaluation of benthic invertebrate samples in rivers“.
