Plants and the Chemical Elements Biochemistry, Uptake, Tolerance and Toxicity
This book summarises many of the important aspects of this very large topic. In Chapter 1, Brian Davies sets the scene with a review of soil chemistry and in particular bioavailability of trace elements to plants, and discusses how we assess this. In the second Chapter Aradhana Mehra and Margaret Farago give a general account of the role of some elements in plant life. In Chapter 3 Mark Macnair and Alan Baker discuss the rapid evolution of adaptation to high concentrations of potentially toxic elements to give metal tolerant plants. This is followed by a review of plants that hyperaccumulate metals by Robert Brooks (Chapter 4), and it is suggested that these plants represent the ultimate in plant tolerance to extremely hostile edaphic environments. Robert Hay discusses the plant enzymes that require enzymes for activity in Chapter 5, and in particular concentrates on their chemistry and structure. In Chapter 6, J. Vangronsveld and H. Clijsters examine some aspects of the toxic effects of metals on plants, in particular those which occur at the cellular level. The pathways and mechanisms involved in the incorporation of man-made nuclides into plants are examined by G. Shaw and J. N. B. Bell in Chapter 7. The use of plants to indicate and biomonitor both natural mineralisation and anthropogenic pollution is discussed in Chapter 8 (Margaret Farago). Finally, the experimental techniques used in the study of elements in plants are discussed; methods of multielement analysis for the determination of concentrations in plant tissues (Chapter 9, Margaret Farago and Aradhana Mehra) and phytochemical methods where the role of the element within the plant is deduced (Chapter 10, Margaret Farago).
