Sulfate (SO42-) contamination in groundwater and surface water is an environmental problem of extensive issue. In this study, we combined steady isotope analyses of SO42- (δ34S and δ18O) and water (δ2H and δ18O) with a Bayesian blending design (SIAR), for the first time, to spot resources and transformation of SO42- in a place of north Asia with numerous possible sources of pollution. The general values of δ34S and δ18O-SO42- ranged from 1.3‰ to 16.3‰ and -3.8‰-8.8‰ in groundwater, and from -1.1‰ to 9.3‰ and 2.7‰-9.2‰ in surface seas, respectively. Analyses of SO42- isotopes and water chemistry indicated that SO42- in groundwater and surface water mainly originated from blending of oxidation of sulfate, sewage, chemical fertilizers, dissolution of evaporite and precipitation. There was no significant correlation between δ34S and δ18O and SO42- focus in groundwater, suggesting that bacterial sulfate reduction did not impact the SO42- isotopic composition. SIAR design revealed the main types of SO42- in groundwater and surface water comprised oxidation of sulfide minerals and sewage. In groundwater, oxidation of sulfide minerals and sewage accounted for 37.5-44.5% and 35.5-42.7% of SO42-, correspondingly. In regard to surface waters, the contribution of oxidation of sulfide nutrients to SO42- had been higher when you look at the wet-season (31.8 ± 9.9%) compared to the intermediate (22.4 ± 7.8%) and dry (20.9 ± 8.2%) periods, nevertheless the contribution proportion of sewage ended up being slightly low in the wet-season (19.9 ± 8.5%) than in the advanced (23.8 ± 8.7%) and dry (24.2 ± 8.5%) periods. This research shows that it's required for municipality to boost the procedure infrastructure for domestic sewage and optimize methods of agricultural fertilization and irrigation to avoid SO42- contamination of groundwater and surface water.As a promising fungicide, the possibility ecological chance of trifloxystrobin (TFS) and its particular main metabolism trifloxystrobin acid (TFSA) in soil environment must be provided unique interest. The present study investigated the possibility risks of TFS and TFSA in soil environment to earthworms (Eisenia fetida) through measuring several biomarkers. Residual analysis indicated that TFSA had been more steady than TFS in artificial soil with half-lives including 138.6 to 231.0 d and 20.4-24.7 d, respectively. Additionally, the accumulation of TFS in earthworms increased at first then reduced from day 14, while compared to TFSA continually enhanced. At levels of 4.0 mg/kg and 10.0 mg/kg, the weight and lysosomal membrane layer security of earthworms had been paid off; nevertheless, the superoxide dismutase (SOD) activity, glutathione-S-transferase (GST) task and malondialdehyde (MDA) content in earthworms had been enhanced by TFS and TFSA. More over, the development inhibition effect and the oxidative damage level induced by TFSA to earthworms were greater than those induced by TFS. The transcriptome evaluation day indicated that the differentially expressed genes (DEGs) in both TFS and TFSA remedies were primarily enriched in ribosome path and lysosome path, finally influencing the protein synthesis and proteolysis in earthworms. The results of this present research suggested that TFSA may present an increased danger into the earth environment than TFS.Removal of Hg(II) by biochar (BC) is a promising remediation technology. The high-salinity Spirulina residue (HSR) is a hazardous waste produced during extracting the pigment phycocyanin under high salinity conditions. Although HSR-derived BC (HSRBC) exhibited the excellent sorption ability of Hg(II), the involved components were hardly ever examined. In this research, we investigated the specific properties and Hg(II) sorption mechanisms of HSRBCs. Chloride and calcium minerals were created in HSRBCs. Increments in carbonization temperature (from 350 to 700 °C) or time (from 90 to 540 min) generated the enhancement of aromaticity, porosity, and good charge, but cracked oxygen-containing groups and C-N bonds. Additional rise in carbonization heat or time decreased the sorption of Hg(II). At environmentally appropriate concentration of Hg(II) (2-4 mg/L), the sorption ability (6.1-12.7 mg/g) gotten in HSRBC350 was comparable to triggered carbon. Considering dual-mode isotherm, area sorption taken into account 75-88% uptake, while precipitation accounted for 12-25% uptake. In addition, the C-O, CO, and CC groups had been accountable for the monodentate/bidentate complexation and decrease, while Cl- triggered Hg2Cl2 precipitation. Overall, this research provided an innovative new understanding in generating a great Hg(II) sorbent from dangerous waste, and disclosed the sorption mechanisms for Hg(II) uptake.In modern times, the Chinese federal government has made great attempts to jointly get a handle on and prevent smog, particularly good particulate matter (PM2.5). But, these efforts are challenged by technical limitations because of the considerable temporal and spatial heterogeneity of PM2.5 across China. In this research, the Affinity Zone Identification Approach (AZIA), which combines tpx-0005 inhibitor rotated major component analysis (RPCA) with modified clustering analysis, was developed and employed to regionalize PM2.5 pollution in China centered on information from 1496 quality of air tracking websites recorded from 2013 to 2017. Two clustering methods, cluster evaluation with analytical test (CAST) and K-center-point (K-medoids) clustering, were compared and revised to eliminate unspecified websites. Site zonation was eventually extended to your municipality scale for the capability of the controlling actions. The results disclosed that 17 affinity zones with 5 various labels from clean to heavily polluted places could be identified in China. The heavily polluted places had been mainly situated in main and east Asia in addition to Xinjiang Province, with local average annual PM2.5 concentrations higher than 66 μg/m3. The newest strategy provided more comprehensive and detailed affinity zones than gotten in a previous research (Wang et al., 2015b). The North China Plain and Northeastern China had been both further divided into north and southern components according to different pollution amounts.
