“Overall, this is a useful reference book for researchers and postgraduate students working in the area of metal/metalloid contamination in soil. Its strength is in environmental chemistry.”  (European Journal of Soil Science, 1 June 2009)“The book is a comprehensive resource for environmental, agricultural, horticultural, and industrial researchers and scientists. It is also an excellent reference for regulators and practitioners in soil and environmental sciences and graduate students in related courses.” (APADE, 2009) "This book is an important contribution to the literature on soil contamination by metals and its remediation." (Journal of Hazardous Materials, April 2008)"It can be a very useful guide to the PhD students and scientists interests in environmental science and engineering, soil chemistry, mineralogy, biochemistry and microbiology as well as plant nutrition and physiology in relation with soil and biophysico-chemical processes."
