“…Here, nanotechnology enables the reduced the usage of precious metals as catalysts within the same process delivering the same end product. Similarly, in their screeninglevel LCA, Meyer et al (2010) did not consider the end-of-life phase because the nano-silver was assumed to have been washed off during the use phase and hence the EOL was assumed to be the same as for non-nano-silver socks. Likewise, the LCA study by Roes et al (2007) assumes no difference in the environmental impacts during the use phase between conventional material and nanocomposites and assumes incineration to be the default EOL for both, and hence, does not discuss these two phases.…”

“…Their case study on CNTs (2008) incorporates this approach where the potential release pathways according to the material size range are documented as part of the assessment. Meyer et al (2010) employ similar reasoning in their qualitative assessment of release of nanosilver from socks. This approach is developed fully by Köhler et al (2009).…”

Purpose The need for a systematic evaluation of the human and environmental impacts of engineered nanomaterials (ENMs) has been widely recognized, and a growing body of literature is available endorsing life cycle assessment (LCA) as a valid tool for the same. The purpose of this study is to evaluate how the nano-specific environmental assessments are being done within the existing framework of life cycle inventory and impact assessment and whether these frameworks are valid and/or whether they can be modified for nano-evaluations. Method In order to do that, we reviewed the state-of-the-art literature on environmental impacts of nanomaterials and life cycle assessment studies on ENMs and nanoproducts.

“…Parameters like energy consumption both for the nanomaterials' production and the construction of facilities and equipment [180], water utilisation and long-term impacts, such as greenhouse gas emissions [181], which are associated to nanoproducts should be reassessed during their life cycle. Traditional waste management methods should be replaced due to the advances in nano-ecotoxicology that can detect trace levels of nanowastes [182].…”

-Manufacturing of nanomaterials is an interdisciplinary field covering physics, chemistry, biology, materials science and engineering. The interaction between scientists with different disciplines will undoubtedly lead to the production of novel materials with tailored properties. The success of nanomanufacturing depends on the strong cooperation between academia and industry in order to be informed about current needs and future challenges, to design products directly transferred into the industrial sector. It is of paramount importance the selection of the appropriate method combining synthesis of nanomaterials with required properties and limited impurities as well as scalability of the technique. Their industrial use faces many obstacles as there is no suitable regulatory framework and guidance on safety requirements; specific provisions have yet to be established in EU legislation. Moreover, regulations related to the right of intellectual properties as well as the absence of an appropriate framework for patent registration are issues delaying the process of products' industrial application. The utilization of high-quality nanomaterials is now growing and coming to the industrial arena rendering them as the next generation attractive resources with promising applications. Undoubtedly, the existing gap between basic research relating nanomaterials and their application in real life will be overcome in the coming decade.

“…Life cycle assessment (LCA) is an established tool for identifying environmental "hot spots" and for comparing products that provide the same services (Walser et al 2011). Using LCA to assess NMs would assist in defi ning their impact on the environment, on human health and on other life forms; when performed LCA should address all production stages, products used and their environmental impact (Walser et al2011, Meyer et al 2011.…”

Abstract:The aim of this paper is to present characteristics, toxicity and environmental behavior of nanoparticles (NPs) (silver, copper, gold, zinc oxide, titanium dioxide, iron oxide) that most frequently occur in consumer products. In addition, NPs are addressed as the new aquatic environmental pollutant of the 21 st century. NPs are adsorbed onto particles in the aquatic systems (clay minerals, fulvic and humic acids), or they can adsorb environmental pollutants (heavy metal ions, organic compounds). Nanosilver (nAg) is released from consumer products into the aquatic environment. It can threaten aquatic organisms with high toxicity. Interestingly, copper nanoparticles (Cu-NPs) demonstrate higher toxicity to bacteria and aquatic microorganisms than those of nanosilver nAg. Their small size and reactivity can cause penetration into the tissues and interfere with the metabolic systems of living organisms and bacterial biogeochemical cycles. The behavior of NPs is not fully recognized. Nevertheless, it is known that NPs can agglomerate, bind with ions (chlorides, sulphates, phosphates) or organic compounds. They can also be bound or immobilized by slurry. The NPs behavior depends on process conditions, i.e. pH, ionic strength, temperature and presence of other chemical compounds. It is unknown how NPs behave in the aquatic environment. Therefore, the research on this problem should be carried out under different process conditions. As for the toxicity, it is important to understand where the differences in the research results come from. As NPs have an impact on not only aquatic organisms but also human health and life, it is necessary to recognize their toxic doses and know standards/regulations that determine the permissible concentrations of NPs in the environment.Unauthenticated Download Date | 5/12/18 7:36 AM
