Sediment and biota

In the sediments accumulated environmental pollution, which can then be released to the watercourse. The concentrations of the harmful substances reflects the often long-term. Nutrients are fixed to one degree or another in sediments dependent on the surrounding physico-chemical characteristics of the mainly water. For custom analysis of these sample types, contact us for a discussion of sample collection / pretreatment for each survey.

With biota referred primarily biological materials such as fish, mussels, water moss and other aquatic organisms. The levels of pollution in these materials are an important source of information for assessing the aquatic ecosystem.
