Engineered nanomaterials (ENMs) are increasingly entering the environment with uncertain consequences including potential ecological effects. Various research communities view differently whether ecotoxicological testing of ENMs should be conducted using environmentally relevant concentrations—where observing outcomes is difficult—versus higher ENM doses, where responses are observable. What exposure conditions are typically used in assessing ENM hazards to populations? What conditions are used to test ecosystem-scale hazards? What is known regarding actual ENMs in the environment, via measurements or modeling simulations? How should exposure conditions, ENM transformation, dose, and body burden be used in interpreting biological and computational findings for assessing risks? These questions were addressed in the context of this critical review. As a result, three main recommendations emerged. First, researchers should improve ecotoxicology of ENMs by choosing test endpoints, duration, and study conditions—including ENM test concentrations—that align with realistic exposure scenarios. Second, testing should proceed via tiers with iterative feedback that informs experiments at other levels of biological organization. Finally, environmental realism in ENM hazard assessments should involve greater coordination among ENM quantitative analysts, exposure modelers, and ecotoxicologists, across government, industry, and academia.

“…Moreover, this study could possibly detect undesirable and ineffective practices of a continuous IDP which was recommend by Lennox et al (2018). In addition, in practice, the findings could be used to improve the sustainability of a project (system) under evaluation (MacCuspie et al, 2014). Finally, this study may provide information (lessons learned) to government and donor agencies that is useful for their future projects.…”

Post‐project sustainability evaluation by using a complex systems approach: A framework and an application to a revolving loan fund (microfinance) project in Indonesia

Limited evidence and less comprehensive approach to post‐project sustainability evaluation has raised the need for incorporating complexity concepts in project sustainability evaluation. This study aims to develop a project sustainability evaluation framework by using a complex systems approach and to apply the framework to a microfinance project in Indonesia. This qualitative research is based on thematic analysis. The components of the proposed framework involve mission, input, process, output, performance, governance (including stakeholders, subsystems and feedback mechanisms) and the environment of the projects. Results show that the framework is able to provide comprehensive information including project sustainability dimensions and routinization, the possibility to detect ineffective or undesirable practices, project governance, its performance, the persistent practice and changes. The application to the microfinance project reveals that the microfinance project can achieve sustainability without subsidies by achieving financial goals while maintaining social missions. Implications for project sustainability and microfinance are discussed.

“…Recently, AOPs are gaining significant importance due to their ability to generate a sufficient number of highly reactive radicals for effective water decontamination. Among numerous AOPs, photocatalysis and sonocatalysis with metal oxide nanoparticles (NPs) have attracted more attention as efficient techniques for the degradation of toxic organic contaminants [9][10][11][12][13][14][15][16][17][18].…”

In recent years, due to the advancement in nanotechnology, advanced oxidation processes (AOPs), especially sonocatalysis and photocatalysis, have become a topic of interest for the elimination of pollutants from contaminated water. In the research work reported here, an attempt has been made to study and establish a physicochemical mechanism for the catalytic activity of copper oxide nanoparticles (CuO NPs) in AOPs using the degradation of dyes as model contaminants. CuO NPs exhibited brilliant sonocatalytic and photocatalytic activities for the degradation of a cationic dye (Victoria Blue) as well as an anionic dye (Direct Red 81). The degradation efficiency of CuO NPs was calculated by analysing the variation in the absorbance of dye under a UV-Vis spectrophotometer. The influence of different operating parameters on the catalytic activity of CuO NPs, such as the amount of catalysts dose, pH of the solution, and the initial dye concentration, was thoroughly investigated. In addition, the kinetic process for the degradation was also examined. It was observed that both dyes exhibited and followed the pseudo-first-order kinetics relation. The rate constant for sonocatalysis was high as compared to photocatalysis. The rate constant for both sonocatalysis and photocatalysis was successfully established, and reusability tests were done to ensure the stability of the used catalysts. To get an insight into the degradation mechanism, experiments were performed by using ⋅OH radical scavengers. The efficacy of CuO NPs for dye decolorization was found to be superior for the sonocatalyst than the photocatalyst.
