This book gives a current overview of all facets of urban soils.
Different urban land-use types in a number of examples worldwide
are introduced. Many examples in different countries are provided
in order to illustrate the situation in detail. The contaminant
sources of urban soils (e.g., dust deposition, contamination along
roadsides, contamination of floodplains, application of wastewater,
anthropogenic deposits) are comprehensively presented. For
practical application purposes a key with which to identify
technogenic materials during field work is presented. Features like
reductomorphic conditions in landfill soils, acidification of coal
mining heaps and the impact of physical characteristics such as
sealing are taken into consideration in the context of the
contamination problem. The mobility of contaminants in the soils
under consideration is introduced and discussed. The content of the
book, however, is not limited to the description of contaminated
urban soils. Different methods of assessment (classification,
functional assessment, assessment focused on pathways with
reference to standardized exposure scenarios) are introduced.
Finally, quality standards for contaminated land in a number of
countries are listed, compared and discussed. The book links up the
contamination problem of urban soils with geographical aspects such
as the historical development of city growth, the process of
urbanization and the urban-to-rural gradients. Accordingly, the
reader will be able to understand the specific problems of
contaminated urban soils and will find sensible approaches to
assessment.
This book provides a comprehensive overview of remediation and
rehabilitation techniques and strategies for contaminated and
anthropogenically disturbed land. Rehabilitation approaches in the
urban environment, such as brownfield redevelopment and urban
mining, are discussed. In relation to contaminated land, techniques
for soil containment and decontamination of soil, soil vapour and
groundwater are comprehensively and systematically presented.
Complicated treatment techniques are schematically depicted and can
be readily understood. Agricultural, silvicultural and
environmentally sustainable rehabilitation strategies for
reclaiming disturbed land/terrain in former mining or
natural-resource extraction areas, such as open-cast mines,
quarries, harvested peatlands, and subsided mining terrain
(sinkholes), are introduced. This book will be a useful tool for
students, researchers, private consultants and public authorities
engaged in the treatment of contaminated or disturbed land.

With more than 50% of the world's population already living in
towns and cities, migration from rural areas continuing at an
alarming rate in developing countries and suburbanisation using
more and more land in developed countries, the urban environment
has become supremely important with regard to human health and
wellbeing. For centuries, urbanisation has caused relatively low
level soil conta- nation mainly by various wastes. However, from
the time of the Industrial Revolution onwards, both the scale of
urban development and the degree of soil contamination rapidly
increased and involved an ever widening spectrum of c- taminants.
With constraints on the supply of land for new urban development in
many countries, it is becoming increasingly necessary to re-use
previously dev- oped (brownfield) sites and to deal with their
accompanying suites of contaminants. It is therefore essential to
fully understand the diversity and properties of urban soils, to
assess the possible risks from the contaminants they contain and
devise ways of cleaning up sites and/or minimizing hazards. The
author, Helmut Meuser, is Professor of Soil Protection and Soil
Clean-up at the University of Applied Sciences, Osnabruck and is
one of Europe's foremost experts on contamination from technogenic
materials in urban soils. He has many years' experience of research
in Berlin, Essen, Osnabruck, other regions of Germany, and several
other countries.
Am Beispiel eines der altesten Industriegebiete der Welt wird hier
die grosse Vielfalt anthropogen gepragter Stadt- und Industrieboden
dargestellt. Besonderes Gewicht legen die Autoren auf die diversen,
die Pflanzenwuchseignungen beeinflussende Bodenparameter. Fur
stadtplanerische Anforderungen sind dabei Bewertungsschemata zum
Schutz von Stadtboden integriert. Daruber hinaus wird die
Schadstoffbelastungssituation und das dazugehorige okologische bzw.
humantoxikologische Gefahrdungspotential typisch urbaner Standorte
aufgezeigt. Fur bedarfsorientierte, stadtplanerische Abwagungen
wird in Verbindung mit der Belastungssituation eine systematische
Beschreibung technogener Substrate (Aschen, Schlacken u.a.)
prasentiert."
