However, with low LL loads both species were able to significantly reduce other compounds (i.e. NH4-N, Cu and Ni). By contrast, Cl, surfactants, and NO3-N, had a tendency to accumulate over time in the effluent and could still represent an actual constraint to large-scale application of the technique. The fate of such pollutants should be investigated with further research to better inform strategies used to manage low amounts of high-concentrated effluent.Phosphorus (P) recovery from wastewater and soil is important for preventing the depletion of P resources; however, a method for recovering P from soil has not yet been developed. We designed and tested systems to recover P from excavated and in situ soil. P extraction from soil using citric acid, EDTA, and water is combined with P retention by calcium (Ca)- and magnesium (Mg)-containing material in both the batch extraction-retention and column percolation approach. In the batch extraction-retention test, Ca hydroxide retained more P than the other materials at 0.38-0.76 mg g-1, and the P was retained as Ca phosphate-like minerals. The amount of P retained by materials using chelating solutions was higher than with water, regardless of the material. The amount of P in the Ca-containing materials after the column percolation test was higher than in the Mg-containing materials, with the exception of Ca carbonate. In the column percolation test, the percentage of P recovery from the available P in the soil was 4.9% and 3.5% using Ca hydroxide and Ca oxide with water, respectively, and the application of chelating solutions did not improve P recovery. In the batch extraction-retention test, the percentage of P recovery using Ca hydroxide and Ca oxide with water was the same as that obtained by the column percolation test; however, the use of chelating solutions could improve the P retention to more than 11% and 7%, respectively. These results demonstrate that more than 10% and 5% of the available P in the soil could be recovered using Ca hydroxide in the batch extraction-retention test with citric acid and EDTA solutions and the column percolation test with water, respectively. The P-retained material may be used as a source for the production of chemical fertilizer.In this research, efficient and novel catalysts based on hierarchical carbon nanohorns-titanium nanoflowers have been prepared by one-pot solvothermal process. Hydrogen generation from dye-contaminated water and dye degradation along with electrochemical supercapacitance performance have been investigated using the synthesized hierarchical catalyst to produce 4500 μmol g-1 h-1 of hydrogen from the photocatalytically generated aqueous methylene blue and methyl orange dyes, which were degraded up to 90% under natural solar light irradiation. These results offer a new path to generate hydrogen from the aqueous dyes. The catalysts electrode showed 164.6 F g-1 supercapacitance at 5 mV s-1 scan rate, which is nearly 1.3 and 1.65-times higher than that of pristine titanium nanoflower and carbon nanohorns electrodes, respectively. Such superior results were achieved due to good crystallinity, improved optical absorption strength, strong chemical composition between the two components, and hierarchical morphology as demonstrated from XRD, UV-DRS, TEM, XPS, and Raman spectral characterizations.Concerns about ammonia (NH3) losses from nitrogen (N) mineral fertilizers have forced policymakers to set emission reduction commitments across Europe. Although best available techniques (BATs) have been recommended, large uncertainties still exist due to poorly targeted site-specific approaches that might compromise their effectiveness. Here we proposed and tested a conceptual framework designed to identify most effective BATs that reduce NH3 at the site-specific level. The study was conducted in the Veneto region, northeast Italy. After the mapping of NH3 emission potential areas, BATs and business-as-usual N fertilization scenarios were assessed using a modified version of the DNDC agroecosystem model and compared with urea broadcast distribution under different pedo-climatic conditions. The most promising practices were further tested in a field experiment using a wind tunnel combined with a FTIR gas analyzer. NSC16168 price Results showed that closed-slot injection reduced NH3 emissions with any type of mineral or organic fertilizers. Injected application, with ammonium nitrate or organic fertilizers, reduced NH3 loss in maize by 75% and 96%, respectively, and in winter wheat by 87% and 98%, compared to surface broadcast. Injection was the most promising technology to support, being already available to farmers. However, some increase in nitrate leaching was observed, mostly in case of winter wheat (+24% for AN injection; +89% for organic fertilizers). By contrast, urea incorporation with hoeing, the most common technique used by farmers in spring crops, did not show satisfactory results, because the partial burial of urea caused strong NH3 emissions that were even higher compared to surface broadcast. Recommended NH3 reduction techniques should be tailored to local pedo-climatic and management conditions, and evaluated, in a holistic approach, considering all N fluxes in the environment.Soil wind erosion is an important ecological environmental problem that is widespread in arid and semi-arid regions. Currently, related studies are mainly focused on spatiotemporal characteristics or analysis of effector mechanisms, and they do not facilitate direct servicing of management decisions. In this paper, we used the Xilingol typical steppe in Inner Mongolia, China, as a study site to develop a decision framework for a comprehensive understanding of soil wind erosion and to promote sustainable management of steppes. In this study, we used the Revised Wind Erosion Equation model to simulate soil wind erosion. We combined this model with linear trend analysis to evaluate the ecological effects of soil wind erosion and wind erosion intensity, and delineated the gravity center migration path. We used the constraint line method to reveal the mechanisms by which climatic factors affected soil wind erosion, achieved the spatial visualization of wind-breaking and sand-fixing service flow, and proposed decision-based regional sustainable development suggestions.
