The anaerobic process is considered to be a sustainable technology
for organic waste treatment mainly due to its lower energy
consumption and production of residual solids coupled with the
prospect of energy recovery from the biogas generated. However, the
anaerobic process cannot be seen as providing the 'complete'
solution as its treated effluents would typically not meet the
desired discharge limits in terms of residual carbon, nutrients and
pathogens. This has given impetus to subsequent post treatment in
order to meet the environmental legislations and protect the
receiving water bodies and environment. This book discusses
anaerobic treatment from the perspective of organic wastes and
wastewaters (municipal and industrial) followed by various
post-treatment options for anaerobic effluent polishing and
resource recovery. Coverage will also be from the perspective of
future trends and thoughts on anaerobic technologies being able to
support meeting the increasingly stringent disposal standards. The
resource recovery angle is particularly interesting as this can
arguably help achieve the circular economy. It is intended the
information can be used to identify appropriate solutions for
anaerobic effluent treatment and possible alternative approaches to
the commonly applied post-treatment techniques. The succeeding
discussion is intended to lead on to identification of
opportunities for further research and development. This book can
be used as a standard reference book and textbook in universities
for Master and Doctoral students. The academic community relevant
to the subject, namely faculty, researchers, scientists, and
practicing engineers, will find the book both informative and as a
useful source of successful case studies.
< p=""> This highly informative and carefully presented book
focuses on the fields of ergonomics/human factors and discusses the
future of the community vis-a-vis health problems, productivity,
aging, etc. Ergonomic intercession must be seen in light of its
effect on productivity because ergonomic solutions will improve
productivity as the reduction of environmental stressors, awkward
postures and efforts lead to a reduction in task execution time.
The book provides promising evidence that the field of ergonomics
continues to thrive and develop deeper insights into how work
environments, products and systems can be developed to meet needs,
demands and limitations of humans and how they can support
productivity improvements. Some of the themes covered are
anthropometry and workplace design, biomechanics and modelling in
ergonomics, cognitive and environmental ergonomics, ergonomic
intervention and productivity, ergonomics in transport, mining,
agriculture and forestry, health systems, work physiology and
sports ergonomics, etc. This book is beneficial to academicians,
policymakers and the industry alike. ^
This comprehensive volume covers recent studies into agricultural
problems caused by soil and water contamination. Considering the
importance of agricultural crops to human health, the editors have
focused on chapters detailing the negative impact of heavy metals,
excessive chemical fertilizer use, nutrients, pesticides,
herbicides, insecticides, agricultural wastes and toxic pollutants,
among others, on agricultural soil and crops. In addition, the
chapters offer solutions to these negative impacts through various
scientific approaches, including using biotechnology,
nanotechnology, nutrient management strategies, biofertilizers, as
well as potent PGRs and elicitors. This book serves as a key source
of information on scientific and engineered approaches and
challenges for the bioremediation of agricultural contamination
worldwide. This book should be helpful for research students,
teachers, agriculturalists, agronomists, botanists, and plant
growers, as well as in the fields of agriculture, agronomy, plant
science, plant biology, and biotechnology, among others. It serves
as an excellent reference on the current research and future
directions of contaminants in agriculture from laboratory research
to field application.
This book details the plant-assisted remediation method,
"phytoremediation", which involves the interaction of plant roots
and associated rhizospheric microorganisms for the remediation of
soil contaminated with high levels of metals, pesticides, solvents,
radionuclides, explosives, crude oil, organic compounds and various
other contaminants. Each chapter highlights and compares the
beneficial and economical alternatives of phytoremediation to
currently practiced soil removal and burial practices.
More than two third of the surface area of our planet is covered by
oceans and assessment of the marine biodiversity is a challenging
task. With the increasing global population, there is a tendency to
exploit marine recourses for food, energy and other requirements.
This puts pressure on the fragile marine environment and needs
sustainable conservation efforts. Marine species identification
using traditional taxonomical methods are often burdened with
taxonomic controversies. Here in this book we will discuss the
comparatively new concept of DNA barcoding and its significance in
marine perspective. This molecular technique can be helpful in the
assessment of cryptic species which are widespread in marine
environment, and can also be used to link the different life cycle
stages to the adult which is difficult to accomplish in marine
ecosystems. Other advantages of DNA barcoding include
authentication and safety assessment of seafood, wildlife
forensics, conservation genetics and detection of invasive alien
species (IAS). Global DNA barcoding efforts in the marine habitat
include MarBOL, CeDAMar, CMarZ, SHARK-BOL, etc. DNA barcoding of
different marine groups ranging from the microbes to mammals is to
be revealed. In conjugation with newer and faster techniques like
high throughput sequencing, DNA barcoding is serving as an
effective modern tool in marine biodiversity assessment and
conservation.
The accumulation of large amounts of contaminants occurs in the
environment due to industrialization and various other
anthropogenic activities. Contaminants ultimately affect human
health worldwide. Organic, inorganic, and radioactive substances
are the prevalent forms of environmental contaminants and their
complete remediation in soils and sediments is rather a difficult
task. Concerns of their toxicities led to the emphasis on
development of effective techniques to assess the presence and
mobility of contaminants in air, water, and soil. Furthermore, the
ever-increasing concentration of toxic pollutants in the
environment is considered a serious threat to plant, animal, human,
and environmental health. Many technologies are in use to clean and
eliminate hazardous contaminants from the environment; however,
these technologies can be costly, labor intensive, and often
distressing to the general public. Phytoremediation is a simple,
cost effective, environmentally friendly and fast-emerging new
technology for eliminating toxic contaminants from different
environments. Phytoremediation refers to the natural ability of
certain plants and their associated microbiome (including
hyper-accumulators or bio-accumulators) to remove, degrade, or
render contaminants harmless. Through this technique, certain
species of plants flourish by accumulating contaminants present in
the environment. The unique and selective uptake capabilities of
plant root and shoot systems, effective translocation,
bioaccumulation, and contaminant degradation capabilities of the
accumulator plants are utilized in phytoremediation techniques.
Phytotechnologies involving the use of plants for contaminant
removal gained importance during the last two decades and
phytoremediation technology became an effective tool for
environmental detoxification because of plants ability to
accumulate the contaminants at very high concentrations.
Phytoremediation strategies can remove, degrade, or stabilize
inorganic and organic contaminants entering a multitude of
ecosystems using green plants and their associated microbial
communities. The development and use of phytotechnologies continues
to move forward at a steady pace. Researchers recognize the
potential of phytoremediation to offer a green, cost effective,
eco-friendly and feasible application to address some of the
world's many environmental challenges. This book provides
significant information to add to the previous volumes published on
the topic and can serve as the foundation for the development of
new applications that feature the integration of modern research
discoveries into new methods to remediate contaminated ecosystems.
Moreover, this volume brings recent and established knowledge on
different aspects of phytoremediation and nano-phytoremediation,
providing this information in a single source that offers a
cutting-edge synthesis of scientific and experiential knowledge on
polluted environments that is useful for policy makers,
practitioners and scientists, and engineers. Phytoremediation:
Management of Environmental Contaminants, Volume 7 highlights the
various prospects that are involved in current global
phytoremediation research. This book delivers a content-rich source
to the reader and can act as a platform for further research
studies. It should meet the needs of all researchers working in, or
have an interest in this particular field.

This volume 'Agrochemicals in Soil and Environment: Impacts and
Remediation' is a comprehensive collection of important literature
on agrochemical contamination. The main focus of this book is to
point out undesirable changes in biological, physical and chemical
characteristics of agricultural soils and its impacts on global
agricultural crop productivity. Soil is one of the important
resources of basic needs for our sustenance but due to various
anthropogenic activities like urbanization and industrialization,
the soil is losing its basic quality characteristics. Soil
microorganisms, water holding capacity, minerals, salts and
nutrients are under the direct threat due to agrochemicals
therefore, agricultural sector is facing a serious challenge. Lack
of proper knowledge and luxurious applications of agrochemicals
resulting into degradation and deterioration of soil quality, loss
of soil and crop productivity and threatening the food security.
Therefore, it is imperative to develop indices, indicators and soil
parameters for the monitoring and impact assessment of agricultural
contaminants. Further, biotic and abiotic stresses and their
tolerance mechanisms in plants in relation to the soil contaminants
such as toxic pollutants, heavy metals, inorganic and organic
matters, variety of pesticides, insecticides, herbicides,
agricultural runoffs and solid wastes, and chemical fertilizers are
also highlighted in this volume. This book also discusses causes of
reduced agriculture productivity and suggests sustainable measures
such as plant-based technologies, bioremediation and
nanotechnology, that can be used to overcome the crop losses. The
book is interest to research students, teachers, agricultural
scientists, agronomists, environmentalists as well as policy
makers.

This book presents a global overview of the background to, and the
current state of, crop protection and pest management in cotton
crops. Cotton is one of the most economically important crops in
the world and has been grown for centuries but maintaining high
yields of good quality requires sophisticated approaches to pest
management. The introduction and use of pesticides over the decades
significantly increased cotton yields but lead to many adverse
environmental impacts. Over time, new and alternative insecticides
were developed but overuse has enabled pests to develop significant
resistance. The development of genetically modified cotton
varieties with toxins derived from Bacillus thuringiensis enabled
much improved control of lepidopteran larvae, including bollworms,
but as the toxins had no effect on sucking pests, farmers had no
choice but to continue using insecticides. Also, some of the new
cotton varieties developed in recent times have not adapted to
different climatic conditions and the quality of cotton fibre
declined as a result. This book shows the need for more research to
select cotton varieties with high quality fibres suitable for
different cotton growing areas and to develop integrated pest
management strategies to minimise the use of pesticides. It also
demonstrates the need for an inter-disciplinary approach bringing
together plant breeders, entomologists, plant pathologists,
agronomists and agricultural engineers to achieve high yields of
high quality cotton. In the future, farmers will need to adopt new
technology to determine when and how pesticides are used in
conjunction with cultural and biological control strategies. *
Emphasises the importance of research on growing cotton in a world
experiencing climate change * Demonstrates how crucial crop
protection is in achieving high yields of high quality cotton *
Shows how new technology will bring major changes in how cotton is
grown in the future
