“…Similarly, in a survey of nearly 200 Swiss companies, it was found that nano-TiO 2 and -SiO 2 were most commonly used (Schmid and Riediker 2008). The same applies to the Japanese construction sector (Suzuki et al 2018b).…”

“…As ENM-containing products reach the end of their useful life, the development of appropriate end-of-life management strategies is critical to minimize human and/or environmental exposure. Several modelling-based studies describing different aspects of discarded ENMs and their fate in the environment (e.g., Boldrin et al 2014;Caballero-Guzman et al 2015;Keller et al 2013;Mueller et al 2013;Mueller and Nowack 2008;Sun et al 2016;Sun et al 2014;Suzuki et al 2018b;Walser and Gottschalk 2014) highlight the important role different waste management processes may play in ensuring appropriate and adequate disposal of ENM-containing products.…”

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.

“…According to these analyzed articles, it can be found that current dynamic MFA research based on C&D waste still focuses on just one waste material. Although considering some materials' life spans, such as 40 years for infrastructures, 38 years for wooden buildings, 39 years for non-wooden buildings, etc., Suzuki et al [48] still concentrated on ENM flows, stocks, and waste processing. A research gap is found regarding utilizing dynamic MFA for mixed wastes processing and analysis.…”

Construction and demolition waste (C&D waste) are widely recognized as the main form municipal solid waste, and its recycling and reuse are an important issue in sustainable city development. Material flow analysis (MFA) can quantify materials flows and stocks, and is a useful tool for the analysis of construction and demolition waste management. In recent years, material flow analysis has been continually researched in construction and demolition waste processing considering both single waste material and mixed wastes, and at regional, national, and global scales. Moreover, material flow analysis has had some new research extensions and new combined methods that provide dynamic, robust, and multifaceted assessments of construction and demolition waste. In this paper, we summarize and discuss the state of the art of material flow analysis research in the context of construction and demolition waste recycling and disposal. Furthermore, we also identify the current research gaps and future research directions that are expected to promote the development of MFA for construction and demolition waste processing in the field of sustainable city development.

“…However, these same authors report that nanomaterials are being used in the medical area, mainly as agents for drug delivery, biosensors, and imaging contrast, i.e., human contact can happen both indirectly and directly, also being administered by ingestion or injection [8]. Once nanomaterials are used, environmental releasing turns dependent on the incorporation form of this product in each matrix, intrinsic material properties and also environmental conditions [9]. When there is human exposure or direct intake of nanomaterials, nanoparticles' physicochemical properties and its possible modifications can influence absorption, distribution, and organism metabolism.…”

Nanomaterials - Toxicity, Human Health and Environment

View full text Add to dashboard Cite

Nanomaterials had been used because of the properties they exert in such scale (<100 nm), and they have been used in a wide variety of products like paints, electronics, fabrics, and also personal care products. Recent manuscripts available in the literature demonstrate the potential benefits of nanotechnology with these products. However, when released in the environment or when in contact with the human body, it is hard to track their final destination and their influence over the living beings. So, since nanomaterials were considered an important technology, a concern about its risks also started. Due to the variety of sizes, physicochemical properties, and uses, many researchers are aiming to assess the possible toxicity of this class of particles. Because of that, the chapter objective is to gather which assay, performed in vivo and in vitro, is the most frequently used and recommended to measure nanomaterial toxicity. Also, it is important to know which is the most suitable test to evaluate the toxicity over the environment, through direct effect and after biodegradation, and also related to human health. This chapter presents a concise review about the accepted methods to assess nanomaterial toxicity and also discuss about the need for regulamentation.
