Xenobiotics: Their activity and mobility in plants and soils

This paper examines the benefits and problems that have arisen from the use of xenobiotics in modern agriculture. Factors which control the transport and metabolism of xenobiotic molecules in plants and soils are considered, with emphasis being placed on the identification of topics which, in the opinion of the authors, are appropriate for increased research activity. The various approaches that are currently used for the analysis of xenobiotic residues in biological materials are also reviewed briefly.
