Abstract:
... Every accident affecting industrial or nuclear facilities emits micrometric fragments of material into the environment whose elemental and isotopic compositions are characteristic of the process or event. Particle analysis, mainly implemented in the framework of the Non Proliferation Treaty to detect clandestine nuclear activities, provides a powerful tool to identify the origin of the nuclear par ...

Abstract:
... Maximizing the health, productivity, and sustainability of ruminant animals is an essential societal goal for a variety of reasons including food security, impact on the environment, and global nutrition; however, monitoring the metabolism of ruminant animals is currently a time-consuming and imprecise process. An indwelling robot residing within the ruminant gut would likely revolutionize metabol ...

Abstract:
... The severe indoor/outdoor air contamination caused by hazardous particulate matters (PMs) has a devastating impact on the environment and human health. Herein, air filters fabricated from delignified wood aerogels and metal–organic frameworks (MOFs) were used for PM removal. Two specially designed MOFs (i.e. Zn-based ZIF-L and Zr-based UiO-66-NH₂) were deposited into a highly porous wood matrix th ...

Abstract:
... Failures of mine tailings storage facilities (TSF) can have profound and long-lasting effects on the downstream receiving environment. Virtually all spills to date have been into river systems without large lakes that may buffer downstream impacts. In August 2014, the failure of the Mount Polley copper (Cu)-gold mine TSF in British Columbia, Canada, released ~25 × 10⁶ m³ of water and solids; globa ...
... High phosphorus steel slag and carbonized rice husk are two common wastes characterized by high generation and low secondary use values. Through the reduction of high phosphorus steel slag by biomass, both wastes were fully utilized, thus reducing the negative impact on the environment. In this study, variables such as temperature, time, and amount of reactants were changed to determine the optima ...
... Tools to address the mismatch between technological and phenolic maturity of grapes are needed. Application of elicitors could be an effective alternative. This work compares the effect of the application of methyl jasmonate (MeJ) in conventional form and, as a novelty, in the form of MeJ-doped nanoparticles (ACP-MeJ) on the phenolic composition of Tempranillo grapes. Results showed that, regardle ...

Abstract:
... Climate change mitigation potentials of carbon capture and utilization (CCU) closely depend on the energy and chemicals used to capture the chemically inert CO₂. The potential environmental benefits of CCU are typically assessed using Life Cycle Assessment (LCA) methodology. Although LCA is a standardized method, modelling CO₂ as a carbon feedstock instead of an emission introduces an ambiguous “m ...

Abstract:
... Acoustic technologies provide a non-invasive method to generate information about the health, welfare, and environmental impact of livestock. This study demonstrated that rear leg attached acoustic sensors can be used to differentiate between seven different acoustic classes, with six based on cow behaviours (Grazing, Breathing, Walking, Lying Down, Dung, Vocalization, Other) that were obtained fr ...

Abstract:
... One of the primary objectives of the negative carbon dioxide gas power plant (nCO₂PP) is to develop an innovative technology confirming the possibility of the use of sewage sludge to produce electricity while having a positive impact on the environment. In this paper, a mathematical model is presented to estimate thermodynamic parameters of the system in relation to the gasification process and ch ...

Abstract:
... Offshore wind power contributes to the decarbonization of the power system; however, its green development faces many challenges, including environmental impact concerns, scale limitations, and grid parity to go carbon neutral. This study applies life cycle assessment (LCA) to evaluate the potential environmental impact of China's first high-power prototype windfarm. The environmental impact of th ...

Abstract:
... Evaluating the embodied environmental impact of solar photovoltaic (PV) technology has been an important topic in addressing the sustainable development of renewable energy. While monetization of environmental externality is a remaining issue, which should be carried out in order to allow for an easy-to-understand comparison between direct economic and external cost. In this study, the environment ...

Abstract:
... Enriched trace elements in coal are considered to have a high environmental impact, but the extent of the influence of the enrichment level is unclear. To study the chemical speciation and environmental behavior of trace elements in coal at different enrichment levels, representative coal samples from multiple provinces in China were collected, including bituminous coal I-L2 from Inner Mongolia wi ...

Abstract:
... Agriculture is a major contributor to nitrate groundwater contamination. Hence, farmers are demanded to reduce the environmental impact but simultaneously must provide sufficient food products. One important building block for this “sustainable intensification” are appropriate cropping strategies. The potential of modified crop rotations was evaluated in a high-yielding environment in Northern Ger ...
... Plastics are versatile and pervasive materials, useful in countless applications and industries. Nevertheless, their high disposal and environmental stability are raising concerns and microplastics are now considered emerging food contaminants by moving all the way up the food chain. High level of uncertainty remains regarding the risks derived from human dietary exposure to microplastics. The aim ...

Abstract:
... Patterns of protein intake are strong characteristics of diets, and protein sources have been linked to the environmental and nutrition/health impacts of diets. However, few studies have worked on protein profiles, and most of them have focused on specific diets like vegetarian or vegan diets. Furthermore, the description of the environmental impact of diets has often been limited to greenhouse ga ...
