Available in PDF, EPUB and Kindle. Book excerpt: The environment is prone to suffer pollution and toxic insult from generations of nanomaterials as well from accidental releases during production, transportation, and disposal operations. The NMs could interact with and cause adverse biological effects at cellular, subcellular, and molecular levels. Assessing potential environmental/ecological risks requires quality information on transport and fate of nanoparticles in the environment, exposures and vulnerabilities of organisms to the nanomaterials and standard methods for assessing toxicity for aquatic or terrestrial organisms and human health. The systematic risk characterization and evaluation of the safety of nanomaterials require a multidisciplinary approach and convergence of knowledge and efforts from researchers and experts from toxicology, biotechnology, materials science, chemistry, physics, engineering, and other branches of life sciences. Although studies are beginning to appear in the literature addressing the toxicity of various nanomaterials and their potential for exposure, at this stage definitive statements regarding the impacts of nanomaterials on human health and the environment remain sketchy requiring an increased level of precautions with regard to nanomaterials, as has happened with other emerging contaminants and technologies (e.g., biotechnology). The need for an increased level of understanding the perception of risk and of benefits will vary and is likely to influence public, regulatory, and non-governmental activities regarding risk and benefit evaluations. Systematic identification and assessment of the risks posed by any new technology are essential. A prudent, integrated, and holistic approach is required to develop best practices based on the scientific understanding about what we know and what we don’t know but need to know. Nanomaterials addresses key issues of ecotoxicological actions and effects of nanomaterials on life and environment, their threats, vulnerability, risks, and public perception. The readers learn to read bad news objectively and think about and search for ecological ‘green’ solutions to current environmental and ecological problems with blue, grey, brown, and red shades for building a sustainable ecosystem. It shows how this molecular terrain is a common ground for interdisciplinary research and education that will be an essential component of science, engineering and technology in the future. The book is divided into three sections. Section I includes general topics related to ecotoxicity of nanomaterials to microbes, plants, human and environment. Section 2 incorporates risks generated by the use of nanomaterials. Section 3 discusss safety issues and the public.

Available in PDF, EPUB and Kindle. Book excerpt: Although nanotechnology is considered to be a key enabling technology and manufactured nanomaterials are an integral part of our everyday lives, there are concerns on the safety of some of the established and newer applications of traditional and more advanced nanomaterials. Therefore, the need to examine how nanomaterials are perceived by the public is important. This study investigates the public perception of manufactured nanomaterials as a group, and their use in different consumer products together with shopping habits, trust in authorities, preferred information sources and labelling requirements among the general population in five European countries - Austria, Bulgaria, Finland, France and Poland. The data was collected using the Computer-Assisted Web Interviewing (CAWI) methodology survey in February 2020. The survey questionnaire was drafted based on a literature search concerning the perception of nanomaterials or nanotechnologies as reflected in published literature. This desk research also provides hypotheses which are further analysed in the study together with trends over time, regional differences, socio-demographic factors, and cognitive drivers affecting the public perception of nanomaterials.

Download or read book Research Progress on Environmental Health and Safety Aspects of Engineered Nanomaterials written by National Research Council and published by National Academies Press. This book was released on 2013-12-25 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the increase in funding for research and the rising numbers of peer-reviewed publications over the past decade that address the environmental, health, and safety aspects of engineered nanomaterials (ENMs), uncertainty about the implications of potential exposures of consumers, workers, and ecosystems to these materials persists. Consumers and workers want to know which of these materials they are exposed to and whether the materials can harm them. Industry is concerned about being able to predict with sufficient certainty whether products that it makes and markets will pose any environmental, health or safety issues and what measures should be taken regarding manufacturing practices and worldwide distribution to minimize any potential risk. However, there remains a disconnect between the research that is being carried out and its relevance to and use by decision-makers and regulators to make informed public health and environmental policy and regulatory decisions. Research Progress on Environmental, Health, and Safety Aspects of Nanomaterials evaluates research progress and updates research priorities and resource estimates on the basis of results of studies and emerging trends in the nanotechnology industry. This report follows up the 2012 report A Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials, which presented a strategic approach for developing the science and research infrastructure needed to address uncertainties regarding the potential environmental, health, and safety risks posed by ENMs. This new report looks at the state of nanotechnology research, examines market and regulatory conditions and their affect on research priorities, and considers the criteria for evaluating research progress on the environmental, health, and safety aspects of nanotechnology.

Available in PDF, EPUB and Kindle. Book excerpt: From nuclear power to gene therapy to the automobile, history shows that it is useful to encourage and facilitate public discussion about new technologies and their potential dangers. Part of the series Perspectives in Nanotechnology, Nanotechnology and the Public: Risk Perception and Risk Communication assesses results from focus groups, interviews, and other resources to provide a more nuanced understanding of how non-experts perceive nanotechnology and what they expect from it. Includes a series of special essays by social scientists and humanities scholars who have studied nanotechnology and society from different perspectives Assessing how "ordinary" people form opinions about new technologies and their adoption, this book addresses the role of media messages and pre-existing values in this process, as well as how risks can become either amplified or weakened along the way as a result of social mechanisms. Using solid theory and research to back presented concepts on risk perception and communication, the author discusses the potential for using informed consent, labels, and other types of consumer warnings that have proved to be effective in areas other than nano. An in-depth investigation into the concept of mass communication practices, this book explores the paradox of why, despite its appeal and promise, public engagement has had only limited success in the dialogue on nanotechnology. Aimed at finding solutions, the book’s resulting conclusions are considered in the context of broader issues. These include how society makes up its collective mind about technology adoption and all the profound questions this raises, in terms of democratic theory.

Download or read book Nanotoxicology in Safety Assessment of Nanomaterials written by Henriqueta Louro and published by Springer Nature. This book was released on 2022-05-18 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its advent, nanotechnologies are considered key enabling technologies that take advantage of a wide array of nanomaterials (NMs) for biomedical and industrial applications generating significant societal and economic benefits. However, such innovation increases human exposure to these substances through inhalation, ingestion or dermal contact raising public health concerns. Furthermore, the NMs’ specific physicochemical properties, that confer them unique beneficial characteristics, can also elicit nano-bio interactions leading to toxicity and concerns for public health. In addition, such properties can be affected by the surrounding matrix, particularly when incorporated in complex matrices such as food products, leading to secondary features potentially more relevant than primary characteristics for determining their toxicological outcome. These nano specific issues raise the question of whether the NMs may produce adverse outcomes that are not accounted for when using conventional toxicological approaches to assess their safety. Such uncertainties about the safety of NMs for human health and the environment may hamper a faster and more widespread exploration of their potentials. In response, the NMs definition has evolved, and nanotoxicology has developed towards new and more integrative approach methods to support regulatory and policy actions. This book provides a perspective on recent developments in the synthesis, application, and characterization of NMs and the related nanotechnologies, focusing on nanotoxicology for their accurate safety assessment early in the product development stage. The use of complex in vitro models, including multicellular systems and organoids, and “omics-based” approaches, such as transcriptomics or epigenomics, have greatly contributed to an in-depth understanding of the cellular and molecular mechanisms behind some NMs toxicity. Such mechanistic knowledge is equally addressed in this book and has set the basis for a predictive nanotoxicology approach building on adverse outcome pathways. In addition, considering the knowledge provided by the above-mentioned approaches, insights into risk assessment, standardization, and regulation of NMs are also included. Incorporating adequate nanosafety assessment early in the life-cycle of NMs will allow the implementation of the safe and sustainable-by-design paradigm enabling safety to keep pace with innovation.
