“…Some studies evaluated release to the environment from a restricted set of PM-ENMcontaining products during the consumption or use phase [62][63][64][65]. Other studies modeled release throughout the whole life cycle of PM-ENM-containing products, including ENM production and manufacturing of products, use, recycling, and disposal [66,67].…”

“…First, the CeO 2 is completely dispersed in the fuel and is exposed to high temperatures just prior to its release into the environment [63]. Because most of the CeO 2 is captured by diesel filters or the catalytic converter [78], its pathway to the landfill and to recycling is more important than for the other ENM [63] (Fig.…”

Abstract-The risks associated with exposure to engineered nanomaterials (ENM) will be determined in part by the processes that control their environmental fate and transformation. These processes act not only on ENM that might be released directly into the environment, but more importantly also on ENM in consumer products and those that have been released from the product. The environmental fate and transformation are likely to differ significantly for each of these cases. The ENM released from actual direct use or from nanomaterial-containing products are much more relevant for ecotoxicological studies and risk assessment than pristine ENM. Released ENM may have a greater or lesser environmental impact than the starting materials, depending on the transformation reactions and the material. Almost nothing is known about the environmental behavior and the effects of released and transformed ENM, although these are the materials that are actually present in the environment. Further research is needed to determine whether the release and transformation processes result in a similar or more diverse set of ENM and ultimately how this affects environmental behavior. This article addresses these questions, using four hypothetical case studies that cover a wide range of ENM, their direct use or product applications, and their likely fate in the environment. Furthermore, a more definitive classification scheme for ENM should be adopted that reflects their surface condition, which is a result of both industrial and environmental processes acting on the ENM. The authors conclude that it is not possible to assess the risks associated with the use of ENM by investigating only the pristine form of the ENM, without considering alterations and transformation processes.

“…These particles were selected based on their widespread use and/or life cycle characteristics; for example, TiO 2 ENMs are one of the most common nanomaterials in production (Holden et al, 2014) and are used in a wide variety of industrial and consumer applications that will likely result in their introduction into the terrestrial environment (Weir et al, 2012;Gottschalk et al, 2009;Johnson et al, 2011;Kaegi et al, 2008), such as through the concentration of TiO 2 in biosolids during waste water treatment that are then used as agricultural fertilizer (Gottschalk and Nowack, 2011;Wang et al, 2012). CeO 2 ENMs are used in several common industrial processes and as a catalyst in diesel fuel, where they are expelled in exhaust and deposited from the atmosphere onto the land surface (Park et al, 2008;Batley et al, 2013;Dahle and Arai, 2015). Kocide 3000 is a nano-Cu(OH) 2 based pesticide manufactured by DuPont (DuPont, 2010) that is specifically developed to be applied to produce and consequently will be directly or incidentally introduced into soils.…”

Gravity-driven transport of three engineered nanomaterials in unsaturated soils and their effects on soil pH and nutrient release

a b s t r a c tThe gravity-driven transport of TiO 2 , CeO 2 , and Cu(OH) 2 engineered nanomaterials (ENMs) and their effects on soil pH and nutrient release were measured in three unsaturated soils. ENM transport was found to be highly limited in natural soils collected from farmland and grasslands, with the majority of particles being retained in the upper 0e3 cm of the soil profile, while greater transport depth was seen in a commercial potting soil. Physical straining appeared to be the primary mechanism of retention in natural soils as ENMs immediately formed micron-scale aggregates, which was exacerbated by coating particles with Suwannee River natural organic matter (NOM) which promote steric hindrance. Small changes in soil pH were observed in natural soils contaminated with ENMs that were largely independent of ENM type and concentration, but differed from controls. These changes may have been due to enhanced release of naturally present pH-altering ions (Mg 2þ , H þ ) in the soil via substitution processes.These results suggest ENMs introduced into soil will likely be highly retained near the source zone.

Recently the number of materials and goods produced by nanotechnology has been growing rapidly, leading to an increased penetration of nanoparticles into biosystems. To assess the risks associated with the production and circulation of nanoproducts should be developed methods for the rapid diagnostics of nanopathology. In this work, it has been experimentally shown that the introduction of metal oxides nanoparticles (TiO2, ZnO, Al2O3, CeO2) to laboratory mice leads to changes some profiles of specific hematological and biochemical blood parameters. Therefore for the purpose of early detection of symptoms of intoxication as benchmarks of the influence of metal oxide nanoparticles on living organisms can recommend express monitoring of peripheral blood (red blood parameters) and biochemical parameters of blood serum (activity of aminotransferases and indicators of nitrogen metabolism). The chosen indicators of blood can serve as diagnostic biomarkers in the development of rapid tests of primary monitoring of the impact of metal oxide nanoparticles on biological systems.
