Download or read book Nanoparticles in Humans written by Lev S. Ruzer and published by CRC Press. This book was released on 2017-01-06 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: A peek into the literature on the environmental health implications of the rapidly developing nanotechnology industry shows that the potential problem of exposure to airborne nanoparticles has not been adequately addressed. The health and safety of nanotechnology workers are of concern because these groups run the greatest risk of exposure to elevated concentrations of nanomaterials. However, a gap exists between the currently available particle measurement methods and those appropriate for the assessment of nanoaerosol exposure. This book presents new ideas and methods to measure the surface area and local deposition of nanoparticles in the lungs and the true value of respirators. It proposes a nanoparticle dosimetric road map that can be used as a general strategy for the assessment of the dose, which is the most important physical cause of adverse effects on health in the case of nanoparticle exposure. The book suggests the use of 1 nm radioactive particles, called unattached activity of radon progeny, as a safe experimental tool for nanoparticle studies, including human studies. It discusses the problems related to the general strategy of risk assessment in nanoparticle exposure and concrete parameters related to dosage. The ideas presented in this book help close the gaps in our knowledge of aerosols in the nanometer range and improve our understanding of nanoparticle behavior in the air and in the human body.

Download or read book Nanotechnology written by R E Hester and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanotechnology is a much talked about, and rapidly expanding area of science, which is sometimes little understood. It looks set to make a significant impact on human life and, with numerous commercial developments emerging, will become a major industry over the coming years. Nanotechnology can be broadly described as developing or exploiting products at nanometre dimensions (i.e. as having one dimension less than 100 nanometres). Such materials have a larger surface area to volume ratio than conventional materials which provides them with an increased level of reactivity, and consequently, toxicity per unit mass. This book sets the subject into context by first of all describing the current range of products containing nano-materials and then looking at the consequences for the environment and human health relating to the introduction of nanoparticles and nano-tubes. Nanotechnology: Consequences for Human Health and the Environment discusses some of the more controversial issues associated with the field including: nanoparticles in the environment, occupational exposure, toxicological properties, human health issues and safety. This authoritative and comprehensive book will be of interest to both scientists and technologists but also to regulators and government.

Download or read book Aerosol Science written by Ian Colbeck and published by John Wiley & Sons. This book was released on 2014-01-30 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: AEROSOL SCIENCE TECHNOLOGY AND APPLICATIONS Aerosols influence many areas of our daily life. They are at the core of environmental problems such as global warming, photochemical smog and poor air quality. They can also have diverse effects on human health, where exposure occurs in both outdoor and indoor environments. However, aerosols can have beneficial effects too; the delivery of drugs to the lungs, the delivery of fuels for combustion and the production of nanomaterials all rely on aerosols. Advances in particle measurement technologies have made it possible to take advantage of rapid changes in both particle size and concentration. Likewise, aerosols can now be produced in a controlled fashion. Reviewing many technological applications together with the current scientific status of aerosol modelling and measurements, this book includes: Satellite aerosol remote sensing The effects of aerosols on climate change Air pollution and health Pharmaceutical aerosols and pulmonary drug delivery Bioaerosols and hospital infections Particle emissions from vehicles The safety of emerging nanomaterials Radioactive aerosols: tracers of atmospheric processes With the importance of this topic brought to the public's attention after the eruption of the Icelandic volcano Eyjafjallajökull, this book provides a timely, concise and accessible overview of the many facets of aerosol science.

Download or read book Exposure Characterisation and Sources of Nanoparticles in Workplace Environments written by Ana Sofia Godinho da Fonseca and published by . This book was released on 2016 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exposure to micro- and nano-scaled particles has been widely linked to adverse health effects including pulmonary, cardiovascular and nervous system disease leading to increased mortality and morbidity rates. With regard to population exposure, indoor microenvironments constitute a particularly vulnerable source given that adults spend on average 60 - 80% of their time indoors, and approximately 50% of it in the workplace. The fast development and spread of innovative technologies and processes used in many industrial sectors (with and without relation to nanotechnology) have benefited from advances but new risks and uncertainties related to possible exposure to unknown nanoparticle types and concentrations may arise. In the workplace, workers may be exposed to nanoscale particles while dealing with engineered nanoparticles (ENP) or process-generated nanoparticles (PGNP) during specific industrial processes involving unintentional nanoparticle release or the formation of nanoparticles from gaseous precursors. Due to the relative novelty of "nanosafety" as a field of research, relevant studies about ENP and PGNP release and exposure under real-world conditions are relatively scarce. Furthermore, adequate analytical techniques and monitoring instrumentation have only recently become available. To date, specific online instrumentation for the targeted detection of nanoparticles in real-time is lacking. The goals of this PhD thesis were to (i) assess the performance of novel instrumentation for nanoscale aerosol measurements, and (ii) to carry out exposure assessments to nanoparticles emitted in workplaces under real-world operating conditions, focusing on ENP and PGNP. The scenarios selected for exposure characterisation were single- walled carbon nanotubes (SWCNT) manufacturing and application processes, and tile ablation and sintering with laser technologies used in the ceramic industry. In addition to emissions and potential particle transformations in workplace air, the potential for particle release to the outdoor environment, and the effectiveness of control measures were assessed in both types of exposure scenarios. The results obtained are presented in the form of five research articles. Results regarding the assessment of monitoring instrumentation concluded that only through the combination of diverse monitoring techniques and parameters does it become possible to obtain a detailed characterisation of nanoparticle exposure routes and scenarios. In the study where workers' quantitative exposure to SWCNT while manufacturing conductive thin films was assessed, it was found that the conventional production and application of SWCNT showed only very limited nanoparticle emissions into the workplace air, with exposure concentrations below the occupational exposure limits available. However, a failure of the local exhaust ventilation in reactor process may give rise to high airborne nanoparticle concentrations near the worker breathing zone (exceeding the recommended exposure limits). The measurements performed in ceramic industries showed that ENP are not the only source of workplace exposure to nanoparticles. Also important can be the exposure to PGNP. High-thermal processes applied frequently in ceramic industries such as tile sintering and ablation, may give rise to nanoparticle exposure concentrations which are significantly higher than those registered in industries which use ENP as input materials. Nanoparticle exposure concentrations in workplace air during these high-thermal processes were, in addition, statistically significant and considered above the exposure limit (4 x 104 cm-3). Thus, the contributions of PGNP to the total nanoparticle workers exposure should not be ignored in risk assessments. Industrial control measures should be proposed and tested specifically for this type environment, tailored to its needs. The effectiveness of the mitigation measures in place in the environments assessed during this PhD thesis were tested and results showed that the use of appropriate strategies may reduce worker exposure to nanoparticles (ENP and PGNP) by up to 98%.
