The quality of stagnant and running water controlled by moss
The accumulation capacity of Fontinalis antipyretica for metals has been investigated. Moreover, the release of the same elements once accumulated by the moss has been studied considering different water chemistry conditions. The release of metals was observed during a period of 133 days and in time, with the moss being exposed to uncontaminated lakewater, the content of elements decreased to 72%. At different pHs (3.7, 8.1 and 10.9) respectively, the adsorption capacity of the moss is exhausted within between 4 and 14 days. The positioning of moss thallus in work station number 6, known to be contaminated, evidenced a significant mercury accumulation, from 0.2 to 26.4 mg/kg following 28 days of exposure. Moreover three of nine stations, where moss samples were exposed for 28 days, have shown high concentration of Cu, Cr and Pb.
