“…In order to provide biologically meaningful estimates of metal contamination in natural waters, biological monitors have frequently been used in various monitoring programs (Claveri et al, 1994(Claveri et al, , 1995Croteau et al, 1998;Cenci, 2001). Among primary producers, aquatic mosses, because of (i) their widespread distribution in lotic ecosystems (if not present, mosses are easily transplanted to sites under investigation (Fernandez et al, 2006)), (ii) their ecological importance, (iii) their ability to accumulate trace metals to easily measurable levels (Claveri et al, 1994), and (iv) their ability to rapidly (days to weeks) respond to a change in ambient metal concentration (Nimis et al, 2002), fulfil most of the criteria for suitable environmental biomonitoring, as shown by their use in various monitoring programs (Cenci, 2001). Despite their long history as biomonitors, there has been little attempt to develop theoretically based models to rigorously relate metal concentrations in mosses to those in water.…”

Chemosphere, Elsevier, 2009, 74, pp.1117-1124. 10.1016/j.chemosphere.2008 Modelling exchange kinetics of copper at the water-aquatic moss (Fontinalis antipyretica) interface: Influence of water cationic composition (Ca, Mg, Na and pH) b s t r a c tThe present study investigated the effect of water cationic composition (Ca, Mg, Na, pH) on the bioaccumulation and elimination rates of copper by an aquatic moss (Fontinalis antipyretica), under laboratory conditions. For this purpose, mosses were exposed to copper at an environmentally relevant and usually non-toxic concentration (5 lg L À1 ) in natural waters where cationic composition and concentrations were varied.To describe copper bioaccumulation by aquatic mosses, a two-compartment model was the first-order kinetics, was developed and calibrated under a wide range of water cationic composition. Bioaccumulation rates of Cu in mosses were significantly reduced as the concentrations of competitive cations in solution increased. Hence, in hard-water, Ca and Mg cations play a protective role as they compete with Cu 2+ ions for the absorption on transport sites at the organism-water interface. Based on the relationships between each major cation concentration and the exchange kinetics on mosses, the binding constants (K C i BL ) of each competing cations to the biological surfaces were derived. Using the present cationicdependant kinetic model, it is now feasible to incorporate water cationic composition in the (re)interpretation of bryophytes contamination levels and in the (re)definition of Water Quality Criteria (WQC) as illustrated through two selected examples of biomonitoring programmes. In the framework of future national water quality guidelines revisions, a such flexible and mechanistic biomonitoring tool (integrating the protective effects of competing cations) may greatly improve the ability of regulators to derive site-specific Cu (metal) guidelines for protecting aquatic biota, while limiting the use of conservative assumptions.

“…Aquatic bryophytes have been referred to in literature as being able to shut off, retain and accumulate pollutants, such as nutrients, toxic organics and heavy metals, leading to a concentration in their tissues several times higher than in the surrounding environment (Nimptsch et al, 2005). Because of their physiological and environmental characteristics and the fact they are widespread in most European rivers (Whitton et al, 1981), aquatic mosses have also been successfully used as biological indicators of surface waters contaminated by heavy metals or radioisotopes (Nimis et al, 2002;Mouvet, 1985;Bruns et al, 1997;Gonçalves and Boaventura, 1998;Vincent et al, 2001). The use of bioaccumulators to monitor water quality is of particular interest for environmental agencies, owing to the difficulties in assessing metal concentrations in the stream water by a purely instrumental approach (Nimis et al, 2002).…”

“…Their accumulation capacity allows an integration of casual fluctuations in the metal concentration in water during long periods of time. So, aquatic bryophytes proved to be an effective one for the detection of intermittent, sporadic and seasonal pollutant incidents (Gonçalves et al, 1994;Nimis et al, 2002). Srivastav et al (1994) reported the accumulation capacity of aquatic mosses to remove heavy metals from polluted waters.…”

“…Experimental data obtained in laboratory (Srivastav et al, 1994) and from field (Nimis et al, 2002;Hongve et al, 2002) have shown that metal ion uptake by aquatic mosses depends on the selected species. However, Fontinalis antipyretica has been recognised as a good bioindicator for heavy metal contamination (Carballeira and Fernandez, 2002;Bargagli et al, 2002;Figueira and Ribeiro, 2005;Samecka-Cymerman et al, 2005).…”

Abstract:The uptake and release of Pb(II) by Fontinalis antipyretica was studied in laboratory, by exposing the plants to different lead concentrations for 144 h and 335 h contamination and decontamination periods, respectively. A first order kinetic model was fitted to the experimental data to determine the uptake and release constants, k 1 and k 2 , and other relevant parameters. The metal accumulation capacity, at equilibrium, follows the order: Pb(II) > Zn(II) > Cd(II) > Cr(VI). A Bioconcentration Factor (BCF) and a Biological Elimination Factor (BEF) were also determined; for 0.9-2.2 mg Pb l -1 , BCF decreases from about 30748 to 21296. Keywords

The concentrations of Cr and Pb were determined in bryophytes and pteridophytes sampled in a stream near a tannery in Guarapuava, southern Brazil. The concentrations of Cr and Pb were measured by cathodic and anodic voltammetry, respectively. These plants were used to evaluate the spatial distribution of elements in the examined stream, and contained elevated levels of Cr (0.71-24.07 μg/g) and Pb (4.33-24.20 μg/g). Chromium levels in plants near the tannery greatly exceeded background levels, indicating a severe to extreme degree of contamination with this metal. Lead levels were elevated to a lesser degree, indicating slight to moderate contamination for most plants collected near the tannery.
