“…Specific properties of plants that may serve as indicators of contamination have been sought. These bioindicators include contaminant concentrations in plant tissues (Farago 1994) and lichen (Richardson 1988) as well as enzyme production and activity (Van Assche & Clijsters 1990), together with quantification of specific metabolite concentrations. For example, phytochelating molecules, such as metal-binding polypeptides induced by uptake of heavy metals, can also be used as bioindicators for contamination (Rauser 1990).…”

Chemical analysis alone is inadequate for comprehensively assessing the impact of soil pollution on biota. The term bioavailability can only be applied in a context specific to a target biological receptor or a proven chemical surrogate. Integration of biological and chemical data can often yield significant advances in hazard assessment and act as a suitable baseline for making site-specific risk assessments. Here, the value of biological techniques is discussed and their application described. The relative merit of test selection is considered and the new direction being developed in sublethal assessments. Currently, however, one of the major limitations is the seeming lack of flexibility of many assays in that they are either applicable to agricultural systems or industrial scenarios, but rarely to both. As a consequence, few assays have internationally adopted protocols. The introduction of new methods and the continued improvement and refinement of assays make this area of soil science dynamic and responsive.

“…It would be interesting to identify the contribution of dry and wet atmospheric depositions and the uptake by roots on the amount of trace metals in leaves. Findings for Pb (Wierzbicka, 1995) are available, but for other trace elements little is known and there are different trends depending on various plant species (Farago, 1994;Bargagli, 1998;Reimann et al, 2001b). For example, Alloway (1995) reports that Cd tends to be more available to plants than other heavy metals, including Pb and Cu.…”

“…There are many studies concerned with the detection of metals by geobotanical and biogeochemical methods. Recent reviews are given by Brooks (1983), Shaw (1990), Markert (1994) and Farago (1994). Only brief reference to lichens is made, usually as components of vegetation releves.…”

The importance of mineralogy in determining lichen assemblages occurring on metalliferous rocks and derived soils is discussed with reference to environments enriched in metals from mine and smelter wastes and other sites involving human activities. A study of lichens growing on Cu and Fe sulphide-rich rocks in Scandinavia is presented. This data suggests that the composition of the lichen communities is governed by mineralogy, which influences the mobility and availability of Cu 2+ and Fe 2+ in the environment, rather than the total concentrations of either metals within the substratum. A new lichen community, the Lecideion inopis Purvis, is described characterized by the faithful species Lecidea inops, Psilolechia leprosa and several Cu-rich ecotypes. This community occurs in alkaline environments where Cu is fixed predominantly as a secondary hydroxide or carbonate. Conversely, low pH, Fe sulphide-rich environments, where Cu may also be present, are characterized by the Acarosporion sinopicae, which includes several species with a rusty colouration. Contrasting assemblages rich in terricolous ephemeral species, especially Vezdaea spp. occurring in Pb/Zn-rich environments, and the comparatively species-poor assemblages on Cr and Ni-rich ultrabasic rocks, are also reviewed. Although mine spoil heaps and other mineralized environments are perceived in human terms as toxic, they may support a diversity of lichens, including rare taxa restricted to these sites. The systematic description of these lichen communities in relation to rock mineralogy and chemical processes are necessary if physiological tolerance and speciation are to be understood.
