Plant and soil form an integrated system. Technogenic contamination of soils with potentially toxic
trace elements (PTE) are reflected in the functioning of plants and soil biota. Soil contamination
by PTE has several implications for human health, as well as for the biosphere. Trace element
“biogeogenic cycling” in the environment is an integral function of the ecosystem (aquatic, terrestrial,
and atmospheric). Therefore, the aim of this collective work is to deal with the trace elements
in the holistic environment, considering advancements in the state-of the-art analytical techniques,
molecular biology, and contemporary biotechnology that enhance our knowledge of the behavior
of trace elements in the biogeosphere and organismal levels, i.e., at the cellular and molecular
levels. Various chapters of this book provide the background with appropriate examples to understanding
the trace elements in the biogeosphere on bioavailability, biogeochemistry, biotechnology,
bioremediation, and risk assessment.
