Emerging contaminants are chemical and biological agents for which there is growing concern about their potential health and environmental effects. The threat lies in the fact that the sources, fate and toxicology of most of these compounds have not yet been studied. Emerging contaminants, therefore, include a large number of both recently discovered and well-known compounds such as rare earth elements, viruses, bacteria, nanomaterials, microplastics, pharmaceuticals, endocrine disruptors, hormones, personal care products, cosmetics, pesticides, surfactants and industrial chemicals. Emerging contaminants have been found in many daily products, and some of them accumulate in the food chain. Correlations have been observed between aquatic pollution by emerging contaminants and discharges from wastewater treatment plants. Most actual remediation methods are not effective at removing emerging contaminants. This second volume presents comprehensive knowledge on emerging contaminants with a focus on remediation.

Microplastics and nanoplastics have been recently found in most environmental media and in living organisms, thus representing a serious health concern of yet poorly known adverse consequences. This book summarizes recent findings on the sources, behavior, transformation, toxicity and remediation of microplastics, with focus on soils, water, wastewater, air, soils, plants and corals. Advanced methods for sampling, characterization, removal and degradation of microplastics.

This book focuses on the emerging research in the field of treatment of solid tumors or cancer with new drug delivery systems using nanotechnology. Nanotechnology has given us a good scope for development of new innovative drug delivery strategies to increase the therapeutic efficacy of anticancer drugs with reduced off-target side effects. Cancer is one of the main causes of death worldwide due to the limitations of classical therapies such as low solubility of active drugs, toxic side effects on healthy cells and resistance of tumor cells. These issues are partly solved by the recent development of polymeric nanoparticles, which improve drug absorption and the therapeutic index, while reducing side effects. Drug carriers must be biocompatible, biodegradable and non-immunogenic. Coupled to a ligand that has affinity for that particular cell, polymeric nanoparticles are used to target specifically malignant cells or tissues and, in turn, improve drug stability. This book presents the latest advances in the application of polymeric particles for cancer treatment, with focus on the tumor microenvironment, synthesis, active and passive targeting, patents, targeting over-expressed receptors, tumor-targeting ligands, theranostics, glioblastoma tumors, lung cancer, breast cancer, prostate cancer and pH-responsive nanoparticles

Herbicides constitute about 60% of the total pesticides consumed globally. In India, the use of herbicides started initially in tea gardens and picked up in the 1970s, when the high-yielding varieties of rice and wheat were introduced. Presently, 67 herbicides are registered in the country for controlling weeds in crops including cereals, pulses, oilseeds, fibre and tuber crops, and also in the non-crop situations. These chemicals are becoming increasingly popular because of their efficiency and relatively low cost compared with manual or mechanical weeding operations. The contribution of herbicide to total pesticide use, which was only 10-15% during the first decade of the 21st century, has now increased to about 25% with an annual growth rate of 15-20%, which is much higher than insecticides and fungicides. Though the application of herbicides is minimizing yield loss to a great extent, their residues in the food chain and surface and groundwater create some environmental nuisance particularly to non-target organisms. Research on pesticide residues in India was started during 1970s, when such chemicals were introduced on a greater scale along with high-yielding variety seeds, irrigation and chemical fertilizers for increasing food production. However, the herbicide residue research was not given much emphasis until 1990s. The Indian Council of Agricultural Research initiated a national level programme known as All India Coordinated Research Project on Weed Management through the NRC-Weed Science as the main centre along with some centers of ICAR Institutes and state agricultural universities. Over the last two decades, adequate information was generated on estimation, degradation and mitigation of herbicide residues, which were documented in annual reports, bulletins, monographs and scientific articles. However, there was no consolidated compilation of all the available information providing a critical analysis of herbicide residues. Accordingly, an effort has been made in the publication to compile the available information on herbicide residues in India. This is the first report of its kind which presents the findings of herbicide residues and their interactions in the biotic and abiotic environment. There are 16 chapters contributed by the leading herbicide residue scientists, each describing the present status of herbicide use, crops and cropping systems, monitoring, degradation and mitigation, followed by conclusions and future lines of work.This book will be useful to the weed scientists in general and herbicide residue chemists in particular, besides the policy makers, students and all those concerned with the agricultural production in the country.

This book will be a guiding path to understand the photocatalytic process and mechanism for the deterioration of heavy metals, persistent organic pollutants and pathogens from wastewater.
