Book Description
The production of engineered nanomaterials (ENMs) has grown in last years due to their special physicochemical properties in respect to their bulk counterparts, derived from their small size (1-100 nm). Among the existing ENMs, silver nanoparticles (AgNPs) are widely used in commercial products due to their antibacterial properties. This fact favours their release in the environment, increasing the concern about the hazards that these emerging contaminants might pose for living organisms and human health. Therefore, to understand their effects, it is of paramount importance their characterisation and quantification in environmental and biological samples by adequate analytical methodologies. The research presented in this thesis focuses on the application and improvement of existing analytical methodologies and on the development of new analytical procedures to acquire information about their mobility and bioavailability in soils and also their accumulation, biotransformation and toxicity in edible plants.

Book Description
This comprehensive book covers the environmental issues concerning silver nanoparticles (AgNPs). Following an introduction to the history, properties and applications, the environmental concerns of AgNPs is discussed. In the second chapter, the separation, characterization and quantification of AgNPs in environment samples are described in detail. In the remaining parts of the book, the authors focus on the environmental processes and effects of AgNPs, with chapters on the pathway into environment, fate and transport, toxicological effects and mechanisms, as well as the environmental bioeffects and safety-assessment of AgNPs in the environment. This book is designed to describe current understanding of the environmental aspects of AgNPs. It provides a valuable resource to students and researchers in environmental science and technology, nanotechnology, toxicology, materials science and ecology; as well as to professionals involved in the production and consumption of AgNPs in various areas including catalysis, food products, textiles/fabrics, and medical products and devices. Jingfu Liu and Guibin Jiang are professors at State Key Laboratory of Environmental Chemistry and Ecotoxicology, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences.

Book Description
Molecular Impacts of Nanoparticles on Plants and Algae covers molecular mechanisms of plants/algae related to cellular uptake and translocation of nanoparticles, and genome, transcriptome, proteome, and metabolome responses against it. The book introduces readers to state-of-the-art developments and trends of nanoparticles and plants/algae including interaction of nanoparticles with biological compounds in vitro. Nanoscience and nanotechnology have rapidly been developed in the last few decades, and they have a wide range of applications in industry, medicine, food, and agriculture. In agriculture, nanoparticles (NPs) have successfully been used for growth regulation, crop protection and improvement. They are also employed to cope with plant nutrient deficiencies. A predicted significant increase in the output of NPs will cause the discharge of a remarkable number of NPs to ecosystems, creating a need to understand how to optimize or mitigate their impact depending on their potential impact. These include serious health concerns for living organisms in aquatic, terrestrial, and atmospheric environments as well as human health through their potential existence in plant-based foods. The impact of NPs on living organisms including plants and algae, and uptake, translocation and molecular response mechanisms should be carefully considered before producing and using nanoparticles in large amounts as NPs, when entered to the body, induce changes in gene expressions related to the photosystem, water transport, cell wall formation, and cell division. Further recent studies have showed that NPs are potential agents or stressors to alter proteome, transcriptome, genome and metabolome responses. Impacts of nanoparticles on molecular mechanisms of plants and algae presents the most recent findings on nanoparticle and plant/algae interaction by focusing to molecular response mechanisms at genome, transcriptome, proteome and metabolome levels. In addition, uptake and translocation mechanism of nanoparticles will be assessed both in plant and algae Throughout this book, the latest developments and discoveries will be highlighted as well as open problems and future challenges in molecular mechanisms of plants/algae as a response of nanoparticles. Presents genome, transcriptome, proteome, and metabolome responses in plants/algae, along with cellular uptake and translocation mechanisms Illustrates nano-particle-plant/algae interactions Covers both simple and higher organisms, addressing both algae and plant

Book Description
As nanotechnology enters everyday life, engineered nanoparticles (ENP) will find their way into nature, including surface and groundwater. Here, distinguished experts of water chemistry present dedicated methods for the analysis of nanoparticles in the aquatic environment, their distribution and fate. This includes the influence of complex matrices such as wastewater, brown water with natural organic matter (NOM), and high salt concentrations as well as available and future standardized methods. The background of geogenic, natural nanoparticles is considered in a discussion of known environmental effects, including strategies to test for potential effects on human and environmental health.
