The high surface to<br/>volume ratio of nanomaterials imparts a high reactivity,<br/>which is of interest for novel applications but may raise<br/>concern for the environment. In the absence of<br/>measurement methods, there is a need for modelling to<br/>assess likely concentrations and fate arising from current<br/>and future releases. To assess the capability that exists to<br/>do such modelling, progress in modelling ENM fate since<br/>2011 is reviewed. ENM-specific processes represented in<br/>models are mainly limited to aggregation and, in some<br/>instances, dissolution. Transformation processes (e.g.<br/>sulphidation), the role of the manufactured coatings,<br/>particle size distribution and particle form and state are still<br/>usually excluded. Progress is also being made in modelling<br/>ENMs at larger scales. Currently, models can give a<br/>reasonable assessment of the fate of ENMs in the<br/>environment, but a full understanding will likely require<br/>fuller inclusion of these ENM-specific processes.", "keywords": ["RELEASE", "transformation", "aggregation", "Urbanisation", "METALLIC NANOPARTICLES", "QUANTIFICATION", "SILVER NANOPARTICLES", "01 natural sciences", "6.

Monte Carlo modelling", "description": "Understanding the transformation and transport of manufactured nanoparticles (NPs) in aquatic systems remains an important issue due to their potential hazard. Once released in aquatic systems, NPs will interact with natural compounds such as suspended inorganic particles and/or natural organic matter (NOM) and heteroaggregation will control their ultimate fate. Unfortunately, systematic experimental methods to study heteroaggregation are not straightforward and still scarce. In addition, the description of heteroaggregation rate constants and attachment efficiencies is still a matter of debate since no clear definition exists. In this work, an original cluster-cluster Monte Carlo model is developed to get an insight into heteroaggregation process descriptions. A two-component system composed of NPs and NOM fulvic acid monomers is investigated by considering several water models to cover a range of (relevant) conditions from fresh to marine waters. For that purpose, homo- and hetero- individual attachment efficiencies between NPs and NOM units are adjusted (NP-NP, NOM-NOM and NP-NOM). The influence of NP/NOM ratio, NOM-NOM homoaggregation versus heteroaggregation, and surface coating effects is studied systematically. From a quantitative point of view, aggregation rate constants as well as attachment efficiencies are calculated as a function of physical time so as to characterize the individual influence of each parameter and to allow future comparison with experimental data. Heteroaggregation processes and global attachment efficiencies corresponding to several mechanisms and depending on the evolution of heteroaggregate structures all along the simulations are defined. The calculation of attachment efficiency values is found dependent on NP/NOM concentration ratios via coating effects, by the initial set of elementary attachment efficiencies and influence of homoaggregation. Marine water represents a specific case of aggregation where all particle contacts are effective. On the other hand, in 'ultrapure' and 'fresh waters', a competition between homo- and heteroaggregation occurs depending on the initial attachment efficiencies therefore indicating that a subtle change in the NP surface properties as well as in the water chemistry have a significant impact on heteroaggregation processes.", "keywords": ["SDG 14 \u2013 Leben unter Wasser", "FATE", "0211 other engineering and technologies", "02 engineering and technology", "SILVER NANOPARTICLES", "01 natural sciences", "Nanoparticle", "ddc:550", "105906 Environmental geosciences", "SDG 14 - Life Below Water", "Monte Carlo simulation", "OXIDE NANOPARTICLES", "0105 earth and related environmental sciences", "ddc:333.7-333.9", "Natural organic matter", "NANOMATERIALS", "info:eu-repo/classification/ddc/333.7-333.9", "info:eu-repo/classification/ddc/550", "Surface coating", "ENGINEERED NANOPARTICLES", "Attachment efficiency", "Nanopartide", "TITANIUM-DIOXIDE NANOPARTICLES", "TRANSPORT", "AQUATIC ENVIRONMENT", "TIO2 NANOPARTICLES", "Natural Organic Matter", "13.

The standard LUFA 2.2 test soil was dosed with 68ZnO NPs and soluble 64ZnCl2 to 5 mg kg-1 each, plus between 0 and 95 mg kg-1 of soluble ZnCl2 with a natural isotope composition. After 0, 1, 3, 6, and 12 months of soil incubation, earthworms (Eisenia andrei) were introduced for 72 h exposures. Analyses of soils, pore waters, and earthworm tissues using multiple collector inductively coupled plasma mass spectrometry allowed the simultaneous measurement of the diagnostic 68Zn/66Zn, 64Zn/66Zn, and 68Zn/64Zn ratios, from which the three different isotopic forms of Zn were quantified. Eisenia andrei was able to regulate Zn body concentrations with no difference observed between the different total dosing concentrations. The accumulation of labeled Zn by the earthworms showed a direct relationship with the proportion of labeled to total Zn in the pore water, which increased with longer soil incubation times and decreasing soil pH. The 68Znen/64Znen ratios determined for earthworms (1.09 \u00b1 0.04), soils (1.09 \u00b1 0.02), and pore waters (1.08 \u00b1 0.02) indicate indistinguishable environmental distribution and uptake of the Zn forms, most likely due to rapid dissolution of the ZnO NPs.", "keywords": ["104002 Analytische Chemie", "550", "TRANSFORMATIONS", "FATE", "0211 other engineering and technologies", "Biological Availability", "02 engineering and technology", "01 natural sciences", "Soil", "104002 Analytical chemistry", "104023 Umweltchemie", "ENGINEERED NANOMATERIALS", "MD Multidisciplinary", "Animals", "Soil Pollutants", "105906 Environmental geosciences", "210004 Nanomaterials", "Oligochaeta", "EARTHWORM EISENIA-ANDREI", "0105 earth and related environmental sciences", "ENVIRONMENT", "104023 Environmental chemistry", "KNOWLEDGE GAPS", "[SDU.ENVI] Sciences of the Universe [physics]/Continental interfaces", " environment", "6.
