Student set Biological water analysis, TESS advanced Biology

Function and Applications

Eco-Kit "Biological testing of water quality". The physical, chemical, and bacteriological examination procedures allow an assessment of the momentary water quality. As the variety of species in a body of water decreases with increasing pollution, and thus the composition of the organism societies changes, the biological determination of the water quality provides additional important indications on the water quality and allows conclusions to be drawn on the previous pollution. The species and frequency of indicator organisms at various degrees of pollution are thereby coupled to the water quality classes I to IV.

Benefits

• This kit enables 6 work groups to simultaneously carry out examinations of running and standing waters in the field.
• The enclosed manual containing tables and evaluation sheets for analysis allow assignment to the water quality classes I...IV.
