Increasing home age was associated with greater Pb and As concentrations (5.0 and 0.48 mg/kg per year of home age, respectively), as were peeling paint and garden access. Three main indoor dust sources were identified, with a Pb−Zn−As factor related to legacy Pb sources, a Zn−Cu factor reflecting building materials, and a Mn factor indicative of natural soil sources. For all countries, enrichments compared to global crustal values were Zn > Pb > Cu > As > Cr > Ni with the greatest health risk from Cr, followed by As > Pb > Mn > Cu > Ni > Zn. The objective was to determine trace metal source inputs and home environment conditions associated with increasing exposure risk across a range of international communities. We evaluated trace metal (and metalloid) concentrations (As, Cu, Cr, Mn, Ni, Pb, and Zn) and health risks in indoor dust from homes from 35 countries, along with a suite of potentially contributory residential characteristics. People spend increasing amounts of time at home, yet the indoor home environment remains understudied in terms of potential exposure to toxic trace metals. Relationship between prospect theory and sustainability risk assessment. In this study, it is suggested that prospect theory is suitable for decisions under risk and uncertainty, and it is applicable to integrate sustainability risk assessment and prospect theory in order to fulfil the gap of knowledge. The results showed that random access memory modules, motherboard and power supply are the highest priority risks based on the evaluation of listed twelve sustainability risks. Further, tasks of computer disassembly processes are prioritized by considering risk factors. Using prospect theory, the relationship between loss aversion, reference point, framing and two selves effect, and sustainability dimensions is presented with a sustainability risk assessment point of view. Tomada de Decisão Interativa Multicritério) method for a previous computer disassembly problem is used. In order to evaluate the irrationality and risk attitudes of decision makers in a risky and uncertain environment, the prospect theory-based TODIM (acronym in Portuguese for interactive and multicriteria decision-making, i.e. Prospect theory and its aspects are integrated with the sustainability risk assessment in e-waste recycling. This study aims to develop a decision tool under uncertain and risky conditions for achieving sustainability in electronic waste (e-waste) recycling in circular economy. Decision-making plays an important role during the risk assessment in e-waste recycling. E-waste is a hazardous concept for human health, environment and businesses, and therefore, risk assessment is essential to eliminate or reduce the negative effects of e-waste in a circular economy.
