However, the general parameters (i.e., temperature, pH, turbidity, total solids, fecal coliform, dissolved oxygen, biochemical oxygen demand, phosphates, and nitrates) used in water quality index estimations are unable to identify pollution from industrial wastewater. This study investigated pollution sources at a river pollution hotspot by using the positive matrix factorization (PMF) model. A two-phase sampling collection along a highly polluted river in northern Taiwan was designed. The sampling spots were distributed along the river in Phase I to monitor the spatial variation of river pollutants. A pollution hotspot was determined based on two indices, namely the summed concentrations of metal elements and a metal index (MI). In Phase II, the river water samples were collected from the hotspot twice daily over 30 consecutive days to monitor the temporal variation of river pollutants. Source profiles of metal elements were obtained during the monitoring period. The Phase II samples were then factorized using the PMF model. Factor profiles retrieved from the PMF model were further assigned to industrial categories through Pearson correlation coefficients and hierarchical classification. The results indicated that the main pollution source was bare printed circuit boards (BPCB), which contributed up to 92% of the copper in the pollution hotspot. In terms of MI apportionment of 11 metals related to health effects, BPCB contributed 91% of the MI in high pollution events. Overall, the MI apportionment provides linkages between pollution level and human health. This is an evidence for policymakers that the regulation of the effluents of BPCB is an effective means to controlling copper concentrations and thus improving water quality in the study area.","PeriodicalId":22130,"journal":{"name":"Sustainable Environment Research","volume":"32 1","pages":"1-10"},"PeriodicalIF":4.9,"publicationDate":"2022-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47427398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Raju","doi":"10.21203/rs.3.rs-1239703/v1","DOIUrl":"https://doi.org/10.21203/rs.3.rs-1239703/v1","url":null,"abstract":"Visible light-driven Zn and Mg co-doped TiO 2 nanomaterials were synthesized by varying dopant concentrations in presence of biogenic surfactant Sapindus emerginatus (biogenic extract) via the Sol-gel method and have been successfully applicated to the degradation of Amido Black 10B (AB 10B), an exemplary anionic textile azo dye pollutant. This study explored the potent capping properties of biogenic extract surfactant by encapsulating the Zn/Mg co-doped TiO 2 . In a view to assessing the physical and optical properties of the as-synthesized catalysts, various advanced instrumental techniques were adopted. The Transmission Electron Microscopy and Scanning Electron Microscopy analysis show the formation of small particle sizes (6.9 nm) pertaining to biogenic surfactant-assisted Zn/Mg co-doped TiO 2 (ZMT4S2). The substitutional doping of Zn and Mg into the TiO 2 framework by substituting Ti 4+ ion and the encapsulation of surfactant around catalyst was confirmed by Fourier Transform-Infrared Spectroscopy (FTIR) spectral studies. The surface area of the ZMT4S2 was found to be high (195 m 2  g − 1 ) as compared with undoped TiO 2 (74 m 2  g − 1 ) and Zn (1.00 wt%) / Mg (0.25 wt%) co-doped TiO 2 (ZMT4) (132 m 2  g − 1 ). The red shift in the absorbance was observed for all the catalysts analyzed using UV-Vis-Diffuse Reflectance Spectroscopy (UV-Vis-DRS) confirms the ZMT4S2 showing less band gap of 2.1 eV than other catalysts. Further the electrical property of the catalyst was studied using Electrochemical Impedance Spectroscopy. The results obtained from impedance and Mott-Schotky plots show the reduced electrical resistance and electron hole recombination respectively. The sensitivity of the catalyst towards visible light was confirmed by its band gap energy measurement using UV-Vis-DRS. The anatase phase of all the catalysts was confirmed using powder X-ray diffraction. The composition and wt% of dopants revealed the Energy Dispersive X-ray spectra agree well with the calculated value. The slightly shifted frequency bands (FTIR) further confirmed the doping of Zn and Mg. The characterization analysis reports further accounts for the effective degradation of AB 10B dye (99%) taking place within 20 min of irradiation time at optimized reaction parameters such as best dopant concentration ZMT4, catalyst dosage (100 mg L − 1 ), dye concentration (10 mg L − 1 ) and solution pH 3.","PeriodicalId":22130,"journal":{"name":"Sustainable Environment Research","volume":" ","pages":"1-20"},"PeriodicalIF":4.9,"publicationDate":"2022-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47519434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
