“…Results of the present study accord with those for benthic marine algae (Gutknecht, 1961(Gutknecht, , 1963, Scenedesmus obliquus (Start' et al, 1983), the liverwort Scapania undulata (Whitton et al, 1982) and Zn uptake by bacteria in activated sludge (Nelson et a!., 1981) .…”

“…Sulphates, ammonia, FRP, Cu, Ni, Zn and Cd displayed relatively wide concentration ranges. Other variables, such as pH and Ca, showed little variation in comparison with previous studies (Whitton et al, 1982;Say & Whitton, 1983;Wehr & Whitton, 1983).…”

“…Aquatic bryophytes tend to be highly resistant to elevated pollutant levels in the water. In this study bryophytes species were recorded in waters with Cu at 154.5 pug I-', Ni at 0.17mg1-1,Cdat2.13~g1-'andZnat105.9~g 1 -'; it is worth pointing out that these values are in some cases higher than those previously reported (Whitton et al, 1982;Say & Whitton, 1983;Wehr & Whitton, 1983). The aquatic bryophytes display both high bioaccumulation factors and sensitivity of variation in body metal content in response to variations in environmental levels.…”

“…Significant positive correlations between plant and water concentrations have been found in mosses, liverworts and algae (Whitton et al, 1982;Say & Whitton, 1983;Wehr & Whitton, 1983;Jones et al, 1985;Kelly & Whitton, 1989), but these correlations have often tended to be low, highlighting the complexity and difficulty involved in their interpretation. Many factors affect metal bioaccumulation: these include the heterogeneity of the accumulating organisms (each species concentrates metals in a different way, and within each species there are variations due to age, physiological condition etc.…”

We studied the capacity of five species of aquatic bryophyte to accumulate metals, and the relationship between plant metal content and water composition, on the basis of 170 samples taken from 32 rivers in Galicia (NW Spain). In all cases, only the final two centimetres of the apex were analysed. Scapania undulata was the species with the highest accumulatory capacity, and Fissidens polyphyllus was that with the lowest. Fontinalis antipyretica, Rhynchostegium rtparioides and Brachythecium rivulare displayed intermediate capacities for metal accumulation, but showed a broader range of variation in body concentration in comparison with similar contamination levels. This resolution capacity, together with a greater resistance to pollution and, in the study region, a wider distribution and higher abundance, suggests that the latter two species are the most useful for bioindication studies. Bioaccumulation factors were high for all metals studied, tending to increase with increasing body concentration but decreasing with increasing water concentration. The relationship between metal in plant and filtrable metal in water was low, but statistically significant for all the metals studied except Co in F. antipyretica and Cd, Pb and Co in S. undulata, F. polypllyl1us and B. rivulare. The influence of physical and chemical variables of the water on bioaccumulation was evaluated using step-wise multiple correlation analysis. Bioaccumulation is largely governed by physical and chemical factors, by the concentration of metal in the water and by the bioaccumulation factor of the bryophyte species. Sulphate concentration, pH and to a lesser extent nitrite, ammonia and FRP (filtrable reactive phosphate) appear to be the most important physical and chemical variables governing metal bioavailability.

“…The use of bryophytes to monitor metal pollution has been discussed [Say et al, 1981 ;Shacklette & Erdman, 1982 ;Whitton et al, 1982;Wehr & Whitton, 1983a, b ;Wehr et al, 19831 and the bryophytes Fontinalis antipyretica, Rynchostegium riparioides and Scapania undulata have been recommended for the purpose . However, the elemental composition of only a limited number of species of aquatic bryophytes has been reported and no study of P endiviifolia has been presented.…”

The concentrations of fifteen elements (B, Na, Mg, Al, P, K, Ca, Ti, Mn, Fe, Cu, Zn, Sr, Cd, Pb) in thalli of the sub-aquatic liverwort Pellia endiviifolia (Dicks .) Dum . collected from seven sites in Japan, were analyzed by inductively coupled plasma atomic emission spectrometer (ICP) . The average concentration of major essential elements in the thalli was : 49600 µg g-1 K, 9140 µg g-1 Na, 6740 µg g-1 Ca, 3840 µg g -1 P, and 3060 µg g -1 Mg . Thalli of P endiviifolia from sites polluted by heavy metals (Cu, Zn, Pb) contained high concentrations of these elements (maxima 0 .88% Cu, 0 .55% Zn and 0 .36% Pb in the older thallus), thus demonstrating the potentiality of this liverwort as an indicator for heavy metal contamination .
