Mechanism of Metal Tolerance in Higher Plants,pulations are said to be metal tolerant. This character has been found amongst both wild and crop species. Wild species often show differentiation into ecotypes which can vary in their degree of tolerance; some cultivars of various crop species also show variation in their degree of tolerances.

Sources of Metal and Elemental Contamination of Terrestrial Environments,rs for such metal deposits, frequently using biogeochemical techniques, are a part of our history. These cases of natural ‘pollution’ are, however, relatively localized, and it was not until the recent era of industrialization that widespread contaminations by heavy metals (and other classes of pollutants as well) have occurred.

Reclamation of Metalliferous Mine Wastes,tals. Extraction of low-grade orebodies including as little as 0–2% w/w of recoverable metal inevitably generates large amounts of waste which are commonly discarded in land-based impoundments or tips, and may cover several square kilometres from a single mining venture.

Book 1981logical significance of this disparate assemblage of elements has gradually been uncovered during the twentieth century; the resultant picture is one of ever-increasing complexity. Several of these elements have been demonstrated to be essential to the functions of living organisms, others appear to

Evaluation of Cytomechanical Propertiesthe materials lost. The limited data available support this assumption (Bormann and Likens, 1979; Woodwell .., 1975). Just as for major nutrient cations, the availability of trace metals to undisturbed ecosystems is determined largely by the balance of weathering release and hydrological loss.

In large concentrations, many of the trace elements/metals may be toxic to plants and/or animals, or may affect the quality of foodstuffs for human consumption. These potentially toxic elements include arsenic, boron, cadmium, copper, fluorine, lead, mercury, molybdenum, nickel, selenium and zinc.
