Abstract There has been an unprecedented use of advanced materials, particularly manufactured nanomaterials, in industrial applications and consumer products across several sectors in the last two decades. It has instigated concerns about the sustainability, in particular, risks and uncertainties regarding the interactions of the manufactured nanomaterials with humans and the environment. Consequently, significant resources in Europe and beyond have been invested into the development of tools and methods to support risk mitigation and risk management, and thus facilitate the research and innovation process of the manufactured nanomaterials. The level of risk analysis is increasing, including assessment of socio-economic impacts, and sustainability aspects, moving from a conventional risk-based approach to a wider safety-and-sustainability-by-design perspective. Despite these efforts on tools and methods development, the level of awareness and use of the majority of such tools and methods by stakeholders is limited. Issues of user-friendliness, trust, implementation training, regulatory or authority compliance needs, regulatory acceptance and unsuitability to the users’ needs are some of the factors which have been traditionally known to hinder their widespread use. Therefore, a framework is presented to quantify the readiness of different tools and methods towards their wider regulatory acceptance and downstream use by different stakeholders. The framework diagnoses barriers which hinder regulatory acceptance and wider usability of a tool/method based on their Transparency, Reliability, Accessibility, Applicability and Completeness (TRAAC framework). Each TRAAC pillar consists of criteria which help in evaluating the overall quality of the tools and methods for their (i) compatibility with regulatory frameworks and, (ii) usefulness and usability for end-users, through a calculated TRAAC score based on the assessment. Fourteen tools and methods were assessed using the TRAAC framework as proof-of-concept. The results provide insights into any gaps, opportunities, and challenges in the context of each of the 5 pillars of the TRAAC framework.

AbstractThe efficiency of industry depends upon the working conditions of the equipment and components used in the industrial process. The biggest problems faced by the industries are the problems of erosion and corrosion. The harmful effects of corrosion will lead to material loss, which results from the degradation of the equipment. The degradation of the equipment will cause the breakdown of the plant; moreover, it is a threat to the safety of people, and also from the point of conservation, it can cause the exploitation of available resources. The cost of replacing equipment increases the expense, and it can also result in the temporary shutdown of the plant. The protection of surfaces from the adverse effects of corrosion and erosion-corrosion is a matter of great concern in most industrial applications. Advancements in technology provides a wide range of techniques to overcome adverse conditions. The selection of appropriate technology must be from the viewpoint of their interaction with the environment. This review paper addresses the adverse effects of erosion-corrosion in the present scenario.

Ethylhexyl Phthalate

Di(2-ethylhexyl) phthalate (DEHP) is widely used as a plasticizer in consumer products. People are continuously exposed to DEHP through ingestion, inhalation and dermal absorption. From epidemiological studies, DEHP has been shown to associate with various adverse health effects, such as reproductive abnormalities and metabolic diseases. Health concerns have been raised regarding DEHP exposures; therefore, relevant risk assessment has become necessary through toxicological testing of DEHP. In the past 10 years, an increasing number of DEHP toxicity studies have been using zebrafish embryos as an in vivo model due to their high fecundity, rapid embryonic development as well as optical transparency, which have now been established as an alternative of the more conventional rodent model. The aim of the present paper is to review the effects of acute (from embryo stage to ≤1 week) and chronic (from embryo stage to >1 week) DEHP exposures on zebrafish, which start from the embryonic stage, and to analyze acute and potential long-term effects induced by acute exposure and effects induced by chronic exposure of DEHP upon subjecting to exposures, starting from the embryonic stage to different developmental stages, with a view to facilitate risk assessments on DEHP exposures.

This article discusses the risks associated with nanomaterials. The use of nanomaterials in consumer products and industrial applications is becoming more prevalent owing to their range of benefits. Nanomaterials have found uses in energy production, home appliances, water treatment, novel therapeutic delivery techniques and dietary supplements, consumer electronics, and sports equipment. While considerable attention has been given to the likely commercial advantages associated with nanomaterials, less emphasis has been placed on the development of a systematic approach for characterizing the human health and environmental risks from exposure to nanomaterials. This article first considers the use of nanomaterials in consumer products and the characterization of nanomaterials before describing a systematic evaluation of the hazards associated with nanomaterials. It also examines pulmonary exposure assessment and dermal exposure assessment, along with risk assessment for exposure to nanomaterials. Finally, it outlines research priorities for the development of more refined estimates of nanomaterial risk.

The Impact

Per- and polyfluoroalkyl substances (PFAS) are pollutants that have demonstrated a high level of environmental persistence and are very difficult to remediate. As the body of literature on their environmental effects has increased, so has regulatory and research scrutiny. The widespread usage of PFAS in industrial applications and consumer products, complicated by their environmental release, mobility, fate, and transport, have resulted in multiple exposure routes for humans. Furthermore, low screening levels and stringent regulatory standards that vary by state introduce considerable uncertainty and potential costs in the environmental management of PFAS. The recalcitrant nature of PFAS render their removal difficult, but existing and emerging technologies can be leveraged to destroy or sequester PFAS in a variety of environmental matrices. Additionally, new research on PFAS remediation technologies has emerged to address the efficiency, costs, and other shortcomings of existing remediation methods. Further research on the impact of field parameters such as secondary water quality effects, the presence of co-contaminants and emerging PFAS, reaction mechanisms, defluorination yields, and the decomposition products of treatment technologies is needed to fully evaluate these emerging technologies, and industry attention should focus on treatment train approaches to improve efficiency and reduce the cost of treatment.

Intensive Development

In the last decade, the miniaturization and integration of mechanical, electronic, and optical components has seen intensive development, both for industrial and consumer products. The technology involved in micromanufacturing can be now seen as moving from the academic study phase to that of industrial application. At the same time, the manufacturing industry is being forced to accommodate these changes in products in order to survive in a borderless international market, not only due to technical considerations but in the interest of cost-effectiveness and agility as well. The environment is also a consideration. To accommodate these demands, further scientific and technological advancements will be required. On the other hand, industrial applications should be developed in order to make the output of the manufacturing industries more economically advantageous and sustainable. “Microfactory” is the philosophy of reducing the size of manufacturing machinery and systems to make them appropriate to the size of the products. It is important that there be advances in micromanufacturing to open this potential new stage for cutting edge manufacturing. The microfactory concept was born almost twenty years ago in Japan, but is just now commonly understood and studied worldwide. For this special issue, we called for both academic and practical papers related to the microfactory concept. As the latter category of papers usually tend to be published outside the world of academic journals, it has been difficult for researchers to become familiar with them. However, since practical applications are very important for the prospects of micromanufacturing technologies, we also invited papers that may fall outside our conventional criteria. Unfortunately, a number of important trials and developments could not be included in this issue, but it is our hope that this special issue may provide our readers with some aspects of the micromanufacturing of the near future. I would like to express my sincere gratitude to all authors, reviewers, and editors for their contributions and efforts in realizing this special issue.
