However, the function and mechanism concerning the regulation of the rhizosphere priming effects (RPE) by MME in plant-soil systems remain unclear. In this study, we performed a pot experiment that included two soil types (paddy soil and lou soil), two plant species (sorghum [Sorghum bicolor (L.) Moench] and maize [Zea mays L.]) and three stages of growth (big trumpet, blooming and mature stage) to investigate the MME mechanism of RPE. Both positive (up to 76% at the big trumpet stage) and negative (down to -11% at the mature stage) RPE were observed. A shift in related enzyme activities and microbial biomass indicated that the 'microbial activation' and 'microbial nitrogen (N) mining' hypotheses functioned together at first. The 'preferential substrate utilization' hypothesis then functioned at the latter two stages. After that, according to a correlation analysis method, the MME was introduced to regulate the RPE the availability of soil C and N and the microbial biomass jointly shaped the microbial C N imbalance (MICN), and the microbes then regulated their MME based on the MICN, thus, regulating the RPE. Specifically, the lower MME induced by a higher MICN was responsible for a greater RPE at the big trumpet stage across all the planted treatments, while a higher MME induced by a lower MICN was responsible for the lower or negative RPE at the blooming and mature stages. Overall, these findings demonstrate that the MME shaped by MICN functions as a mediator to regulate the RPE in planted soil.Current studies tend to combine different advanced treatment technologies to reduce costs and increase efficiency. The objective of this work was to assess the combination of ozonation and UV/H2O2 with activated carbon adsorption for the removal of effluent quality parameters and micropollutants from secondary effluent samples. The experiments were carried out using the following configurations O3 + GAC + O3 (1); O3 + GAC + UV/H2O2 (2); UV/H2O2 + GAC + O3 (3); UV/H2O2 + GAC + UV/H2O2 (4). Configurations 1, 3 and 4 were the most efficient for organic matter removal, while configuration 1 had the lowest cost on laboratory scale. An additional ultra-filtration membrane unit (UF) was tested at the end of configuration 1, which was optimized in terms of ozone doses for the removal of three organophosphate micropollutants in ultrapure water (TNBP, TCIPP and TPHP at 10 μgL-1). The best cost-effective configuration of this treatment train was the one using 1 mg L-1 of ozone before and after GAC, which achieved around 100% of micropollutants abatement. The role of each treatment to the final micropollutant removal was also discussed, being the first ozone treatment responsible for about 15% removal of the mixture of contaminants, while GAC was responsible for an additional 80% removal. The complete treatment train reached almost 100% of contaminants removal (under detection limit of the method), as well as added security to the system. The achieved results were also compared to international reuse legislations, proving that the combination of O3 and GAC was an interesting option to achieve enough quality for some reuse purposes.The ubiquitous presence of microplastics in the aquatic environment has raised concern about their potential impacts on and risks to the biota. While the presence of microplastics in a marine environment has been well studied, the impact of microplastic contamination in freshwater bodies is understudied. In the present study, baseline data about contamination with microplastics in Lake Guaíba in southern Brazil are presented. The abundance, distribution, and composition of microplastics in the surface of this freshwater body were investigated, and these parameters were correlated with population density, land occupation, wind, and geohydrologic processes. The samples were collected with a manta net (60 μm mesh size). learn more Microplastics were found in all the samples, with an average of 11.9 ± 0.6 to 61.2 ± 6.1 items m-3, which indicates the widespread contamination of the lake with plastic particles. The most frequent microplastic morphology was the fragment type in the size range of 100 to 250 μm, and the predomintics are more susceptible to variations in their measurements.Environmental heterogeneity and dispersal limitation are important drivers of beta diversity; however, their relative influence on the two fundamental components of beta diversity (i.e., species replacement and richness difference) has not been fully examined in montane streams. Here, we examined the relative importance of local environmental gradients and three physical distance matrices (i.e., overland, watercourse and cost distances) on beta diversity and its two components for a macroinvertebrate metacommunity in a stream network. To provide additional insights into community assembly, we also analysed variation in two deconstructed sub-communities based on dispersal ability (i.e., weak and strong dispersers). Both environmental filters and physical distances (dispersal limitation) drove patterns of overall beta diversity, with the former generally prevailing over the latter. Species replacement components showed stronger correlations with environmental gradients than physical distances, while the opposit.Environmental implications of climate change are complex and exhibit regional variations both within and between the polar regions. The increase of solar UV radiation flux over Antarctica due to stratospheric ozone depletion creates the optimal conditions for photochemical reactions on the snow. Modeling, laboratory, and indirect field studies suggest that snowpack process release gases to the atmosphere that can react on sea salt particles in remote regions such as Antarctica, modifying aerosol composition and physical properties of aerosols. Here, we present evidence of photochemical processing in West Antarctica aerosols using microscopic and chemical speciation of individual atmospheric particles. Individual aerosol particles collected at the Brazilian module Criosfera 1 were analyzed by scanning transmission X-ray microscopy with near edge X-ray absorption fine structure spectroscopy (STXM/NEXAFS) combined with computer-controlled scanning electron microscopy (CCSEM) with energy-dispersive X-ray (EDX) microanalysis.learn more
