Making a sense all of it: Honest insights about the situations regarding the initial genome-edited toddlers.More cases of arsenic contamination are reported globally, making the restoration of arsenic in water an active area of research. Especially, As(Ⅲ) is more difficult to remove than negatively charged As(Ⅴ) due to the presence of neutral H3AsO3 in the water, so to achieve efficient separation of As(Ⅲ) in water, it is very important to pre-oxidize As(Ⅲ) to As(Ⅴ). Herein, Fe-coated Cu0 doped MnO2 nanowire membrane (FCMNCM) was successfully prepared to enhance the oxidation of As(Ⅲ) to As(Ⅴ) through the combination of superoxide anion (O2·-) and MnO2 oxidation. Experimental results show that Cu0 activates oxygen to generate O2·-, the generated O2·- not only significantly enhances the conversion efficiency of As(Ⅲ) to As(Ⅴ) but also oxidize the Mn(Ⅱ)/Mn(Ⅲ) produced by the reduction of MnO2 by As(Ⅲ) to Mn(Ⅳ) again to realize multi-channel oxidation of As(Ⅲ), and the maximum separation efficiency of As(Ш) can reach 99.34%. Acidic conditions are favorable for the separation of As(Ш), and carbonate and phosphate have a serious negative effect on As(Ⅲ) separation by competing for the active site. Anti-fouling and repeatability experimental show that FCMNCM is an environmentally friendly material with long service life and excellent reusability, it provides a new platform for As(Ⅲ)-containing sewage treatment.This paper highlights local experiences, opportunities and common challenges faced by micro- and small-sized businesses in Resource Recovery and Reuse (RRR) - with a special focus on briquette making businesses from faecal sludge and other household waste. The study enlisted the potential that RRR has in preserving the environment through through hybrid business models in sanitation. It used field methods of identifying businesses and providing them with business development support, while testing the potential to become sustainable faecal sludge enterprises. learn more The findings indicated that the small businesses still face several challenges in integrating faecal sludge into the business models profitably. We recommend high level attention by government, academic institutions and entrepreneurs for policy, research and management innovations. This will have a combined benefit of sanitation improvement as well as having entrepreneurial innovations and business growth from waste.Offshore wind power generation requires large areas of sea to accommodate its activities, with increasing claims for exclusive access. As a result, pressure is placed on other established maritime uses, such as commercial fisheries. The latter sector has often been taking a back seat in the thrust to move energy production offshore, thus leading to disagreements and conflicts among the different stakeholder groups. In recognition of the latter, there has been a growing international interest in exploring the combination of multiple maritime activities in the same area (multi-use; MU), including the re-instatement of fishing activities within, or in close proximity to, offshore wind farms (OWFs). We summarise local stakeholder perspectives from two sub-national case studies (East coast of Scotland and Germany's North Sea EEZ) to scope the feasibility of combining multiple uses of the sea, such as offshore wind farms and commercial fisheries. We combined a desk-based review with 15 semi-structured qualitative ifindings represent a comprehensive depiction of the current state and key stakeholder aspirations for multi-use solutions combining fisheries and OWFs. We believe that the pathways towards robust decision making in relation to multi-use solutions suggested here are transferable to other international locations.Olive Mill Wastewater (OMW) is a polluting residue from the olive oil industry. It is usually stored in open-air unprotected evaporation ponds where their sediments accumulate. This study compares the characteristics of OMW sludges stored for long-time in evaporation ponds and assesses their impact on the underlying soil layer. Physicochemical parameters, toxicity bioassays, and full characterization of the microbial community were analyzed. The extension of the polluting effects was assessed by analysis of toxicity, microbial biomass carbon, and respiration. Geostatistics was used to predict their spatial distribution. Organic matter and polyphenol content besides toxicity levels determine variations between OMW sludges and have a high impact on the microbiota they contain. The microbial community was abundant, diverse, and functionally active. However, the biodegradability of the sludges was hindered by the toxicity levels. Toxicity and biomass carbon were higher on the surface of the ponds than in the soil layer revealing a reduced leach flow and depletion of contaminants. learn more The natural microbiota might be biostimulated by means of applying sustainable and feasible biological treatments in order to favor the OMW sludges bioremediation. These results open up the possibility of solving the environmental concern caused by its storage in similar scenarios, which are common in olive oil-producing countries.Coastal eutrophication is a leading cause of degraded water quality around the world. Identifying the sources and their relative contributions to impaired downstream water quality is an important step in developing management plans to address water quality concerns. Recent mass-balance studies of Total Phosphorus (TP) loads of the Maumee River watershed highlight the considerable phosphorus contributions of non-point sources, including agricultural sources, degrading regional downstream water quality. This analysis builds upon these mass-balance studies by using the Soil and Water Assessment Tool to simulate the movement of phosphorus from manure, inorganic fertilizer, point sources, and soil sources, and respective loads of TP and Dissolved Reactive Phosphorus (DRP). This yields a more explicit estimation of source contribution from the watershed. Model simulations indicate that inorganic fertilizers contribute a greater proportion of TP (45% compared to 8%) and DRP (58% compared to 12%) discharged from the ment should not focus solely on an individual nutrient source; rather a comprehensive approach involving numerous sources should be undertaken.
