Bioremediation refers to the clean-up of pollution in soil,
groundwater, surface water, and air using typically microbiological
processes. It uses naturally occurring bacteria and fungi or plants
to degrade, transform or detoxify hazardous substances to human
health or the environment. For bioremediation to be effective,
microorganisms must enzymatically attack the pollutants and convert
them to harmless products. As bioremediation can be effective only
where environmental conditions permit microbial growth and action,
its application often involves the management of ecological factors
to allow microbial growth and degradation to continue at a faster
rate. Like other technologies, bioremediation has its limitations.
Some contaminants, such as chlorinated organic or high aromatic
hydrocarbons, are resistant to microbial attack. They are degraded
either gradually or not at all, hence, it is not easy to envisage
the rates of clean-up for bioremediation implementation.
Bioremediation represents a field of great expansion due to the
important development of new technologies. Among them, several
decades on metagenomics expansion has led to the detection of
autochthonous microbiota that plays a key role during
transformation. Transcriptomic guides us to know the expression of
key genes and proteomics allow the characterization of proteins
that conduct specific reactions. In this book we show specific
technologies applied in bioremediation of main interest for
research in the field, with special attention on fungi, which have
been poorly studied microorganisms. Finally, new approaches in the
field, such as CRISPR-CAS9, are also discussed. Lastly, it
introduces management strategies, such as bioremediation
application for managing affected environment and bioremediation
approaches. Examples of successful bioremediation applications are
illustrated in radionuclide entrapment and retardation, soil
stabilization and remediation of polycyclic aromatic hydrocarbons,
phenols, plastics or fluorinated compounds. Other emerging
bioremediation methods include electro bioremediation,
microbe-availed phytoremediation, genetic recombinant technologies
in enhancing plants in accumulation of inorganic metals, and
metalloids as well as degradation of organic pollutants,
protein-metabolic engineering to increase bioremediation
efficiency, including nanotechnology applications are also
discussed.
This book analyzes the relationship between large-scale industrial
activity and the carbon footprint, and provides a theoretical
framework and tools to calculate the carbon footprint of industrial
activities at every stage of their life cycles, including
urban-planning master plans, recycling activities, project and
building stages as well as managing and manufacturing. Discussing
the main preventative and corrective measures that can be utilized,
it includes case studies, reports on technological developments and
examples of successful policies to provide inspiration to readers.
This book collects the contributions of authors from four
continents, in order to analyze from as many as possible points of
view and using many different approaches, the problem of
sustainability in today's globalized world.
Pollution Control and Resource Recovery: Municipal Solid Wastes
Incineration: Bottom Ash and Fly Ash explains the tools and
technologies needed to characterize, stabilize, treat, recycle, or
properly dispose bottom and fly ash. The public concern for the
environmental impact of MSW incineration has increased
significantly over the last 20 years, forcing manufacturers to
develop, and plants to install and operate, high-cost advanced
technology for pollution control. This book explores the latest
information on this important topic.
This book provides an overview of cleaner production, including how
regulations have evolved, and presents a broad perspective on how
it is being developed. Presenting several practical examples and
applications of modern clean production technologies, it provides
readers with ideas on how to extend these practices to other
industry sectors in order to contribute to a better environment in
the future. The authors start from the initial concepts of how to
implement new cleaner production systems, before collecting recent
developments in the area and demonstrating practical ways in which
the latest knowledge can be applied. It motivates readers to
develop new ideas on how to improve manufacturing systems to save
energy and generate less waste, and discusses strategies on how to
save, reuse and adapt materials, as well as techniques to reduce
the waste and pollution produced. This book serves as a reference
resource for industrial management engineers and researchers, and
is also of interest to undergraduate and postgraduate students
looking for insights into cleaner production in industry.
This volume is a tribute to Professor Otto Hutzinger, the founding
editor of The Handbook of Environmental Chemistry, in recognition
of his pioneering work and contribution to our understanding of the
sources, fate, exposure and effects of persistent organic
pollutants. It consists of fourteen chapters written by individuals
who have been inspired by his work and have followed in his
footsteps by refining our knowledge of this field and opening new
research directions. In Professor Hutzinger's tradition of passing
on valuable information to others, the authors present recent
advances in areas such as inventories, remediation, and analytical
determinations. Levels and trends in abiotic environments, biota,
and human exposure via food, as well as the risks to the
environment and humans from polychlorinated dibenzo dioxins,
furans, and PCBs are also discussed. Other chapters deal with the
relevant topics of DDT and its metabolites along with halogenated
and phosphorus flame retardants.
The aim of this book is to present an overview of the state of the
art with regard to the function, application and design of TWSs in
order to better protect surface water from contamination.
Accordingly, it also presents applications of constructed wetlands
with regard to climatic and cultural aspects. The use of artificial
and natural treatment wetland systems (TWSs) for wastewater
treatment is an approach that has been developed over the last
thirty years. Europe is currently home to roughly 10,000
constructed wetland treatment systems (CWTSs), which simulate the
aquatic habitat conditions of natural marsh ecosystems; roughly
3,500 systems are in operation in Germany alone. TWSs can also be
found in many other European countries, for example 200 - 400 in
Denmark, 400 - 600 in Great Britain, and ca. 1,000 in Poland. Most
of the existing systems serve as local or individual household
treatment systems. CWTSs are easy to operate and do not require
specialized maintenance; further, no biological sewage sludge is
formed during treatment processes. As TWSs are resistant to
fluctuations in hydraulic loads, they are primarily used in rural
areas as well as in urbanized areas with dispersed habitats, where
conventional sewer systems and central conventional wastewater
treatment plants (WWTPs) cannot be applied due to the high costs
they would entail. TWSs are usually applied at the 2nd stage of
domestic wastewater treatment, after mechanical treatment, and/or
at the 3rd stage of treatment in order to ensure purification of
effluent from conventional biological reactors and
re-naturalization. New applications of TWSs include rainwater
treatment as well as industrial and landfill leachate treatment.
TWSs are well suited to these fields, as they can potentially
remove not only organic matter and nitrogen compounds but also
trace metals and traces of persistent organic pollutants and
pathogens. Based on the practical experience gathered to date, and
on new research regarding the processes and mechanisms of pollutant
removal and advances in the systems properties and design, TWSs
continue to evolve.
Remediation of wastewater is important to ensure that pollutants
generated in industry do not effect our environment negatively.
Traditional wastewater remediation is not a sustainable process,
however by using biological means the sustainability can be
improved. This book explores how bioremediation biotechnology is
used to remove pollutants in wastewater. Both conventional methods
bioremediation technologies are discussed.

This volume offers an overview of the occurrence of emerging
organic contaminants in Mediterranean rivers and their relevance to
their chemical and ecological quality under water scarcity. With
chapters covering the effects under multiple stress conditions of
pharmaceuticals, polar pesticides, personal care products, and
industrial chemicals, the observations presented can be applicable
to other parts of the world where water scarcity is an issue . It
is of interest to environmental chemists, ecologists, environmental
engineers, and ecotoxicologists, as well as water managers and
decision-makers.
The use of water for industrial purposes is of foremost importance.
It is used as a coolant and industrial activities dealing with
power generation, steel and iron, paper and pulp and oil require
very large amounts of water. The industry, therefore, resorts to
large scale abstraction of water from natural water bodies. This
water is often treated with chemicals to combat operational
problems like biofouling and corrosion. Such withdrawal and
subsequent discharge of large amounts of water have the potential
to impart significant impact on the recipient water body. The
organisms drawn along with the cooling water, as well as those
residing at the discharge zone, are subjected to a combination of
mechanical, thermal and chemical stress on a continuous basis.
This book presents a range of nanocatalysts, together with their
primary environmental applications and use in chemical production
processes. In addition, it describes the nanomaterials used for
catalysts and details their performance. The book introduces
readers to the fundamentals and applications of nanocatalysis,
synthesis, characterization, modification and application. Further
topics include: landfill organic pollutant photodegradation;
magnetic photocatalysis; synergistic effects on hydrogenated TiO2;
and photoinduced fusion of gold-semiconductor nanoparticles. A
detailed explanation of the chemistry of nanostructures and the
ability to control materials at the nano-scale rounds out the
coverage. Given the central importance of research in
nanotechnology and nanoscience for the development of new
catalysts, the book offers a valuable source of information for
researchers and academics alike. It will also benefit industrial
engineers and production managers who wish to understand the
environmental impact of nanocatalysts.
Pollution has no borders. This popular 70's saying from early
ecologists is surprisingly still true nowadays despite overwhelming
scientific evidence and public awareness of the occurrence of
artificial toxic substances in water, food, air, living organisms
and the environment. This book presents advanced reviews on
pollutant occurrence, transfer, toxicity and remediation. The
chapter on school air quality by Dambruoso et al. highlights the
overlooked health issue of airborne pollutants in buildings.
Children are particularly threatened because they spend 90% of
their time indoors, even in summer. The chapter on industrial
wastewater pollutants by Dsikowitzky and Schwarzbauer reviews
pollutants from textile, petrochemical, paper, tire, chemical and
pharmaceutical plants. The authors describe advanced analytical
methods and ecotoxicity tests. Industrial pollutants include
dioxins and furans that are also reviewed in the chapter by Mudhoo
et al. The chapter on fly ash by Gianoncelli et al. presents many
techniques to treat fly ash and, in turn, decrease pollutant
concentrations. The authors also explain that fly ash can be
recycled in agriculture, buildings and geopolymers. The chapter on
antifouling paints used for ship protection, by Sousa et al.,
highlights the occurrence of toxic organotins in human organs such
as heart, liver and breast milk. The chapter on surfactants by
Rebello et al. focuses on safety concerns for humans and the
ecosystems. Remediation techniques and green surfactants are
presented. The chapters on toxic metals by Nava-Ruiz and
Mendez-Armenta, Abarikwu and Ristic et al. describe sources,
monitoring and diseases induced by lead, mercury, cadmium and
thallium. The chapter on carcinogenic nitrosamines by Li et al.
presents techniques and materials such as zeolites to remediate
liquids and smoke containing nitrosamines.
This book offers a problem-and-solution approach to environmental
remediation in mining, including the environmentally sustainable
utilization of waste materials from the mining industry. It largely
comprises articles published in Springer journals, which have been
thoroughly revised and expanded. With supplementary data and
illustrations, it discusses specific problem areas in relevant
Caribbean locations and provides an overview of geotechnical and
microbial solutions to prevent post-mining deterioration in this
area.
Air pollution related to the release of industrial toxic gases,
represents one of the main
concerns of our modern world owing to its detrimental effect on the
environment. To tackle this growing issue, efficient ways to
reduce/control the release of pollutants are required. Adsorption
of gases on porous materials appears as a potential solution.
However, the physisorption of small molecules of gases such as
ammonia is limited at ambient conditions. For their removal,
adsorbents providing strong adsorption forces must be
used/developed.
In this study, new carbon-based materials are prepared and tested
for ammonia adsorption at ambient conditions. Characterization of
the adsorbents texture and surface chemistry is performed before
and after exposure to ammonia to identify the features responsible
for high adsorption capacity and for controlling the mechanisms of
retention. The characterization techniques include: nitrogen
adsorption, thermal analysis, potentiometric titration, FT-IR
spectroscopy, X-ray diffraction, Energy Dispersive X-ray
spectroscopy, X-ray photoelectron spectroscopy and Electron
Microscopy. The results obtained indicate that ammonia removal is
governed by the adsorbent s surface chemistry. On the contrary,
porosity (and thus physisorption) plays a secondary role in this
process, unless strong dispersive forces are provided by the
adsorbent. The surface chemistry features responsible for the
enhanced ammonia adsorption include the presence of
oxygen-(carboxyl, hydroxyl, epoxy) and sulfur- (sulfonic)
containing groups. Metallic species improve the breakthrough
capacity as well as they lead to the formation of Lewis acid-base
interactions, hydrogen-bonding or complexation. In addition to the
latter three mechanisms, ammonia is retained on the adsorbent
surface via Bronsted acid-base interactions or via specific
reactions with the adsorbent s functionalities leading to the
incorporation of ammonia into the adsorbent s matrix. Another
mechanism involves dissolution of ammonia in water when moisture is
present in the system. Even though this process increases the
breakthrough capacity of a material, it provides rather weak
retention forces since ammonia dissolved in water is easily
desorbed from the adsorbent s surface."
This book is a systematic compilation of the most recent body of
knowledge in the rapidly developing research area of greenhouse gas
interaction with clay systems. Unexpected results of the most
recent studies - such as unusually high sorption capacity and
sorption hysteresis of swelling clays -stimulated theoretical
activity in this fascinating field. Classical molecular dynamics
(MD) explains swelling caused by intercalation of water molecules
and to a certain degree of CO2 molecules in clay interlayer.
However, unusual frequency shifts in the transient infrared
fingerprints of the intercalated molecules and the following
accelerated carbonation can be tackled only via quantum mechanical
modeling. This book provides a streamlined (from simple to complex)
guide to the most advanced research efforts in this field.
