Bio And Nanoremediation Of Hazardous Environmental Pollutants

This book is a compendium of knowledge about nanomaterials and strategies for bioremediation over hazardous environmental pollutants. The book is divided into 2 sections. Section 1 deals with the polluted environment, where it explains that soil is in serious danger and highlights the primary hazardous pollutants. Besides, this section covers algae, autochthonous, introduced, or genetically modified organisms that are used to degrade hazardous contaminants. In Section 2, Bio- and Nanoremediation are shown through synthesis, green synthesis and molecular farming, and their applications or impacts. Moreover, this discusses bio- and nano-remediation, working together for better performance, organisms, and nanomaterials for environmental remediation.

The increased demand due to anthropogenic activity leads to emerging contaminants, resulting in a substantial environmental hazard. The long-term presence and exposure of contaminants lead to severe negative impacts on the environment, humans, and other life forms. Hence, emerging contaminants in the environment is a worldwide concern, and new technologies to mitigate these contaminants are being developed. This book covers the source, occurrence, toxicity, and detection techniques of a wide range of emerging contaminants. This collection also discusses the scope and applications of diverse techniques, including Bio/Phyto and Nano-remediation technologies, to mitigate the emerging contaminants; along with their sustainability issue and prospects. As a result, this book appears to provide insight into several modern and environmentally friendly waste management options, the possibility to minimize and lessen the effects of contaminants, and striving to lower toxicological endpoints to assure environmental safety. This book delivers the most recent advancements by prominent specialists in environmental sciences to academics, researchers, students, and practitioners interested in the identification and eradication of emerging pollutants from the environment.

This book describes many novel approaches of microbial bioremediation including conventional and modern approaches, metagenomics, biosurfactants and nano-based bioremediation.

It also illustrates communication pathways based on evolving methodologies, bioinformatic tools which provides insights into the functional dynamics of bioremediation process by the host-microbiome interface. The different chapters explain the mechanism and outcomes during the process of bioremediation. The book broadly depicts the following: Advances in bioremediation through nanoremediation, rhizo-remediation, bioremediation of different ecosystems like polluted waters, industrial effluents, bioremediation of metal and organic pollutants, toxic dyes etc. The book is very useful for researchers and students in the fields of applied and environmental microbiology. It is also meant for industry experts and professionals working in the field of bioremediation and waste management.

Increased industrial and agricultural activity has led to the contamination of the earth's soil and groundwater resources with hazardous chemicals. The presence of heavy metals, dyes, fluorides, dissolved solids, and many other pollutants used in industry and agriculture are responsible for hazardous levels of water pollution. The removal of these pollutants in water resources is challenging. Bioremediation is a new technique that employs living organisms, usually bacteria and fungi, to remove pollutants from soil and water, preferably in situ. This approach is more cost-effective than traditional techniques, such as incineration of soils and carbon filtration of water. It requires understanding how organisms consume and transform polluting chemicals, survive in polluted environments, and how they should be employed in the field. Bioremediation for Environmental Pollutants discusses the latest research in green chemistry and practices and principles involved in quality improvement of water by remediation. It covers different aspects of environmental problems and their remedies with up-to-date developments in the field of bioremediation of industrial/environmental pollutants. Volume 1 focuses on the bioremediation of heavy metals, pesticides, textile dyes removal, petroleum hydrocarbon, microplastics and plastics. This book is invaluable for researchers and scientists in environmental science, environmental microbiology, and waste management. It also serves as a learning resource for graduate and undergraduate students in environmental science, microbiology, limnology, freshwater ecology, and microbial biotechnology.

The study of the relationship between environmental pollution and human health is in its infancy. The number of substances and mixtures that have been identified in uncontrolled hazardous waste sites or that have been in advertently released into the environment is large and data on how thes~ substances are modified as they interact with one another as they migrate through soil, air, and water are limited. There are also limits on our un derstanding of how these substances may be ingested, inhaled, or absorbed by people. The complexity of possible interactions between biological, chemical, and physical components in a given environment makes it virtually impossible to evaluate the potential for adverse biological effects ade quately in the laboratory. Other, more comprehensive methods which provide realistic and interpretable results must be used. Many scientists believe that humans represent the ultimate sentinel species of a toxic exposure re sUlting from environmental pollution, however such exposures may also se verely impact environmental health. There exists a wide variety of organ isms in the natural environment that could be used to provide an early warning for potential human health effects as well as to indicate adverse ecological effects. The issue of effective utilization of sentinel species for environment al monitoring is a rapidly developing area of research which has grown in importance during the last decade.

Ecotoxicity and Human Health emphasizes the relationships between toxicity, ecological systems, and human health. It focuses on the extent and nature of hazardous waste sites and how their effects may be studied in humans and other systems, using in vitro models, biomarkers of cellular and molecular damage, and animal models. It also includes considerable information on bioremediation, legal and regulatory issues, public perceptions and societal responses, quantitative modeling and analysis, and international directives. One of the unique features of Ecotoxicity and Human Health is its coverage of the legislative actions that have occurred over the past two decades and which have most affected the issue of hazardous waste. The book discusses the Superfund Statute, the Resource Conservation and Recovery Act (RCRA), the Toxic Substances Control Act (TSCA), the Ocean Dumping Act of 1972, the Rio Conference, United Nations Declarations, EC Regulations and Directives, and selected state legislation.

This reference book discusses the applications of microorganisms as a crucial solution for the sustainable management of toxic pollutants. It describes the microbial remediation of different kinds of pollutants like wastewater, antibiotics, and toxic chemicals. It highlights the technical, scientific, regulatory, safety, and societal impacts of various sustainable biodegradation approaches.
