9. Water quality monitoring using biostations

These biostations take advantage of the ability of aquatic plants to grow and continuously accumulate the various pollutants present. In particular, they can detect the presence of pollutants undetectable in water by conventional physico-chemical methods.

In the field, these biostations generally consist of a basin of a few cubic meters, continuously fed with the water to be monitored (figure 8 ). Here, elodea, duckweed or mosses (bryophytes) permanently cultivated in floating tanks accumulate the various pollutants present in the water:...
