Therefore, it is of vital importance to study the occurrence of ECs in the effluents from WWTPs. In this study, the concentration levels and pollution characteristics of typical ECs in effluents were investigated for source identification and risk assessment. In total, 13 of 39 analyzed ECs were detected in the effluents, with the highest detection concentration at 706 µg/L (oxolinic acid). Sulfaphenazole showed the highest detection frequency at 100%, while Liede WWTP (1.2 million m³/day), located at Tianhe District, was with the highest detection concentration (899 µg/L) among all sampling sites. Parallel factor analysis was applied to identify the dissolved organic matters (DOMs) of excitation–emission matrix spectroscopy (EEMS) first. Based on previous research data, the connection between DOMs and pollution sources could be built. Then, principal component analysis (PCA) and Pearson’s correlation analysis were used to determine the correlation between ECs and DOMs. Finally, ecological and health risk quotients were calculated for the risk assessment of ECs. The results illustrated that oxolinic acid, sulfaphenazole, sulfaquinoxaline, sulfadimethoxypyrimidine, penicillin V, and flumequine were potentially discharged from human activities and livestock, poultry, and aquaculture industry; the possible sources of sulfadoxine and nafcillin were agricultural activities, food production, and catering industry; sulfapyridine and erythromycin were believed to come from hospital wastewater; and the discharges of lincomycin, sulfameter, and sulfamerazine were related to petrochemical industry or chemical production activities. Except for sulfadoxine, all detected ECs posed a high or median risk on aquatic ecosystem, which is enough to threaten aquatic organisms. Even though only oxolinic acid, sulfaquinoxaline, and sulfadimethoxypyrimidine presented a potential risk on humans’ health, the cumulative effect of ECs in the human body still needs attention. The threats of ECs from large-scale WWTPs in China’s developed regions are pointed out for the first time, which could possibly bring widespread attention on emerging pollution from WWTP effluents, potentially advance the introduction of relevant policies, and provide the direction and target pollutants for follow-up mitigation actions.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"234 7","pages":""},"PeriodicalIF":2.9,"publicationDate":"2023-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11270-023-06410-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4253299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesized that the amount of P that can be retained from the water column by sediments is positively correlated with their iron content. Column experiments were used to investigate uptake and release of P in the sediments under oxic and anoxic conditions in three downstream lakes (Lake Neuendorfer See, Lake Glower See, Lake Müggelsee) with decreasing mining influence and thus iron loads, and one nearby non-mining-affected lake (Lake Schwielochsee). In lakes interconnected by River Spree, the cumulative P uptake in sediments increased significantly with increasing sedimentary Fe concentrations under both oxic and anoxic conditions. Only the sediments of Lake Glower See had higher P uptake under anoxic than oxic conditions, most likely due to vivianite formation. The net P sedimentation was higher with higher Fe concentration and higher under oxic than anoxic conditions. However, the lakes are classified as eutrophic because although the sediments of the Spree lakes can store further P, this additional P uptake is of little relevance for the P budget in highly P-loaded lakes with short water residence times (10–100 d), as is typical for fluvial-lacustrine systems.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"234 7","pages":""},"PeriodicalIF":2.9,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11270-023-06441-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4212000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From an <i>A. barbadensis</i> Miller root sample, six distinct endophytic bacterial isolates were tested by morphological and biochemical techniques and also characterized respectively. Using the molecular identification approach of 16S rRNA partial gene sequencing, one of the bacterial isolates was identified. The sequence alignment of isolate AM1 showed the similarity in a range of 99-100% in BLAST with different strains of <i>Bacillus</i>. AM1 isolates exhibited the evidence of antibiotic susceptibility, with a minimum inhibitory concentration (MIC) IC₅₀ value against clarithromycin of concentration 1.5 g/mL. The bacterial isolate was susceptible to clarithromycin, erythromycin, ampicillin, and azithromycin but resistant to amoxicillin and tetracycline. The extract and isolate showed 40 to 85% of increasing inhibition in DPPH and ABTS scavenging activities with concentrations ranging between 0.5 and 2.5 mg/ml. The decolorization and degradation efficiency of synthetic dyes Congo red (CR) and Bromophenol blue (BPB) was studied using endophyte bacterial isolate AM1. The biodegradation of CR and BPB was 79% for 8 ppm and 65% for 2 ppm after 192 h of incubation at room temperature with constant pH (7.0). The degradation and the metabolic products formed during the degradation were predicted using Fourier transform infrared (FTIR) spectroscopy. Significant vanadium accumulation was seen in the leaves, roots, and soil remnants of <i>B. juncea</i> plants grown in symbiosis with endophytic bacteria AM1 through High-performance liquid chromatography (HPLC) analysis. This accumulation may be related to AM1 bacteria with effective root colonization.

Considering that Kosovo is characterized by complex geological settings and high mining activity, it is important to assess the risk of heavy metal soil pollution. The research aims to evaluate the level and spatial distribution of some heavy metals and biogenic elements in soil samples throughout the whole territory of the country. The surface soil samples were collected at 0–25 cm depth from twenty-four sampling sites evenly distributed in the study area. Each site comprised five to ten sub-samples within a 50 × 50 m expanse. The concentration of elements (Cd, Pb, Co, Cu, Mn, and Ni) was determined by graphite-furnace atomic absorption spectroscopy (GFAAS). Atomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) were used to determine the levels of Ca, Mg, Na, K, Zn, and Fe, while cold vapor atomic absorption spectroscopy (CVAAS) was used for the determination of Hg. For the processing of experimental data, statistical analyses (descriptive statistics, correlation analysis, and linear regression) were applied, as were cluster and factor analyses. The concentrations of heavy metals and biogenic elements, based on their average values in the soil samples, exhibited the following trend: Fe &gt; Mg &gt; Ca &gt; Mn &gt; K &gt; Cr &gt; Na &gt; Ni &gt; Pb &gt; Zn &gt; Cu &gt; Co &gt; Cd &gt; Hg.

Therefore, the development of Zn-MOF-based nanocomposite ultrafiltration membranes for water treatment is progressing. In this study, synthesized Zn-MOF nanoparticles were incorporated into a poly(vinylidene fluoride-co-hexafluoro-propylene) (PVDF-co-HFP) polymer casting solution to fabricate Zn-MOF/PVDF-co-HFP nanocomposite ultrafiltration membranes via the phase-inversion method. An advanced technique was used to characterize the surface characteristics, morphology, and chemical composition of nanocomposite membranes. Compared to the pristine PVDF-co-HFP membrane, the Zn-MOF/PVDF-co-HFP nanocomposite membranes exhibited better surface characteristics. The obtained results demonstrate that the presence of Zn-MOF nanoparticles on the membranes considerably enhanced their surface charge (zeta potential of − 62 eV), hydrophilicity (contact angle of 71°), porosity, water content, and thermal stability. Moreover, the resultant Zn-MOF/PVDF-co-HFP nanocomposite membranes exhibited noticeably enhanced water permeability (up to 158 L/m² h bar), which was two times greater than that of the pristine PVDF-co-HFP membrane, whereas the bovine serum albumin (BSA) rejection of the nanocomposite membrane remained high (99%) without compromising the flux. The Zn-MOF/PVDF-co-HFP nanocomposite membrane had the highest flux recovery ratio (FRR) value (99%) and the lowest irreversible flux decline ratio (IFDR) value (0.3%).
