“…A study by Sakallioglu et al (2016) showed that the leaching behaviour of nano-ZnO in a MSW batch reactor was not significantly affected by the prevalent pH and ionic strength, where the majority (up to ~ 93 %) of nano-ZnO were retained and adsorbed to the solid MSW matrix. Dulger et al (2016) conducted batch tests under similar conditions and showed that the retention capacity of MSW was sufficient and far from saturation in order to retard nano-TiO 2 . In this context it needs to be mentioned that currently it is very challenging or almost impossible to distinctively differentiate, for example, man-made nano-ZnO from naturally occurring Zn species that occur in relatively high concentrations (up to ~ 100 mg L -1 or higher).…”

Significant knowledge and data gaps associated with the fate of product-embedded engineered nanomaterials (ENMs) in waste management processes exist that limit our current ability to develop appropriate end-of-life management strategies. This review paper was developed as part of the activities of the IWWG ENMs in Waste Task Group. The specific objectives of this review paper are to assess the current knowledge associated with the fate of ENMs in commonly used waste management processes, including key processes and mechanisms associated with ENM fate and transport in each waste management process, and to use that information to identify the data gaps and research needs in this area. Literature associated with the fate of ENMs in wastes was reviewed and summarized. Overall, results from this literature review indicate a need for continued research in this area. No work has been conducted to quantify ENMs present in discarded materials and an understanding of ENM release from consumer products under conditions representative of those found in relevant waste management process is needed. Results also indicate that significant knowledge gaps associated with ENM behaviour exist for each waste management process investigated. There is a need for additional research investigating the fate of different types of ENMs at larger concentration ranges with different surface chemistries. Understanding how changes in treatment process operation may influence ENM fate is also needed. A series of specific research questions associated with the fate of ENMs during the management of ENM-containing wastes have been identified and used to direct future research in this area.

“…To ensure proper convergence to the global minimum, different initial values of the parameters were considered in the iterative least-squares estimation process. [29]. This could be attributed to the large buffering capacity of the waste, which tended to neutralize any changes in the pH made at the beginning of the test and the relatively high initial IS in leachate.…”

“…There is not any documented reference that show how titanium dioxide nanoparticles move from the electrical components dumped on a surface of land or buried in a landfill to the environment. However, a few researches [15] showed that titanium dioxide nanoparticles that are used in consumer goods like cosmetics and textile can be found in leachate of municipal solid waste. The leachate characteristics such as pH, ionic strength and natural organic matter concentration play an important role in how titanium dioxide nanoparticles are released and transported [16].…”

Nanoparticles are small objects that their size, in at least one dimension, is between 1 and 100 nanometers. Nanomaterials characteristics are completely different from larger particles. Therefore, Nanotechnology can be used to enhance the properties of many products. Although it is possible to use nanotechnology to improve the performance and life cycle of various electric components, Alborz Electric Power Distribution Company (AEPDC) efforts have been focused on using TiO2 nanoparticles in street lamps as well as medium voltage silicon rubber insulators. In current paper, the properties of titanium dioxide (TiO2) nanoparticle were described. Then the applications of this nanomaterial in insulators and lamps were explained. Finally, the possible impacts of using it on environment were discussed.
