- The first of these considers the uptake of metals (Cd, Cu, Mn, Pb and Zn) by plants grown in compost under greenhouse conditions.
- The second considers the oral bioaccessibility of metals (Cd, Cu, Mn, Pb and Zn) from plants grown on contaminated compost using an in vitro gastrointestinal extraction approach.
- Case study three discusses the uptake of persistent organic pollutants (a–endosufan, b–endosulfan and endosulfan sulfate) by lettuce plants grown in compost.
- Finally, case study four looks at the oral bioaccessibility of persistent organic pollutants by lettuce plants grown in compost using an in vitro gastrointestinal extraction approach.
This book also contains a useful collection of data sheets that could be used to record laboratory information at the time of carrying out the experiments, plus a guide to selected resources.
This text will be suitable for those carrying out undergraduate courses in environmental science, as well as courses in related disciplines, e.g. chemistry, life sciences, etc. It will also be relevant for postgraduate training courses, including MSc and MRes in environmental science and related disciplines and for researchers interested in the bioavailability and associated features of environmental contaminants.
The Analytical Techniques in the Sciences series of books provides coverage of all of the major analytical techniques and their application in the most important areas of physical, life and materials science. Each text is presented in an open learning/distance learning style, in which the learning objectives are clearly identified. The reader s understanding of the material is constantly evaluated by the use of self–assessment and discussion questions. Series Editor: David J. Ando
