Healthy environment is important for any kind of biota on earth. It
provides the basic elements of life such as clean water, fresh air,
fertile soil and supports ecosystem of the food chain. Pollution
drastically alters quality of the environment by changing the
physico-chemical and biological aspects of these components.
Accordingly, toxic metals, combustible and putrescible substances,
hazardous wastes, explosives and petroleum products are all
examples of inorganic and organic compounds that cause
contaminations. Specifically, pollution of toxic and heavy metal in
the environment is a growing problem worldwide, currently at an
alarming rate. Toxic metals threaten the aquatic ecosystems,
agriculture and ultimately human health. Traditional treatment
techniques offer certain advantages such as rapid processing, ease
of operation and control and flexibility. But, they could not
maintain the quality of the environment due to the high operational
costs of chemicals used, high energy consumption and handling costs
for sludge disposal and overburden of chemical substances which
irreversibly affect and destroy biodiversity, which ultimately
render the soil useless as a medium for plant growth. Therefore,
bioremediation and biotechnology, carried out by living assets to
clean up, stabilize and restore contaminated ecosystems, have
emerged as promising, environmental friendly and affordable
approaches. Furthermore, the use of microbes, algae, transgenic
plants and weeds adapted to stressful environments could be
employed to enhance accumulation efficiency. Hence, sustainable and
inexpensive processes are fast emerging as a viable alternative to
conventional remediation methods, and will be most suitable for
developing countries. In the current volume, we discuss pollution
remediation challenges and how living organisms and the latest
biotechnological techniques could be helpful in remediating the
pollution in ecofriendly and sustainable ways.
