The oceans are a primary source of VHCs, and concentrations and fluxes of selected VHCs in the Yellow Sea and East China Sea were measured. These data, and the influence of marine environmental factors on these parameters, provide information which will permit the assessment of the marine contribution of VHC behaviour and impact. Abstract Concentrations of five volatile halocarbons (VHCs), that is, chloroform (CHCl3), trichloroethylene (C2HCl3), tetrachloroethylene (C2Cl4), bromoform (CHBr3) and chlorodibromomethane (CHBr2Cl), were measured in the South Yellow Sea (SYS) and East China Sea (ECS) during autumn in 2011. The average (min–max) concentrations of CHCl3, C2HCl3, C2Cl4, CHBr2Cl and CHBr3 in surface seawater were 63.91 (24.63–361.23), 28.46 (1.82–85.77), 21.04 (9.85–89.31), 20.92 (7.98–59.89) and 75.91 (0.04–537.04) pmol L−1 respectively. The five VHCs exhibited a point distribution in autumn with clearly defined patterns in certain areas. In the vertical profiles, the highest concentrations of VHCs generally appeared in the upper mixing layer. Different VHCs were correlated with different environmental parameters, such as temperature, salinity, chlorophyll a (Chl-a), nutrient levels and bacteria. These results revealed that the sources of these VHCs were influenced by the Yangtze River effluent and Kuroshio waters as well as the biogenic release. Diurnal bimodal cycles were obvious in the concentrations of the five VHCs in the ECS. In general, concentrations peaked around noon, likely owing to biological production and photochemical mechanisms, and a secondary peak occurred around midnight, possibly resulting from a combination of respiration, zooplankton feeding and tidal action. The estimated sea-to-air fluxes showed that the study area was a net source of the five VHCs in the atmosphere during the study period.","PeriodicalId":11714,"journal":{"name":"Environmental Chemistry","volume":"2 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2021-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86812948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Hematite and the protein bovine serum albumin (BSA) were used as models to investigate the surface chemistry and competitive role of BSA in arsenate adsorption. Results show that surface BSA inhibits arsenate adsorption, potentially altering its mobility and bioavailability.\u0000AbstractThe surface chemistry of metal oxide nanomaterials controls their health impacts and fate in environmental and biological systems. These systems contain proteins capable of binding to nanoparticles, which forms a protein corona that modifies the surface properties of the nanoparticles and reactivity towards pollutants. Using attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy, we investigate the adsorption of bovine serum albumin (BSA) and quantify the competitive effect of BSA on the adsorption kinetics of arsenate, AsV, to hematite nanoparticles. Experiments were conducted in the flow mode at pH 7. BSA was first adsorbed on hematite, then AsV was allowed to flow over the BSA/hematite thin film. Adsorption kinetic and thermodynamic parameters were calculated using a modified Langmuir adsorption model for both BSA and AsV. The adsorption thermodynamic model showed that BSA binds through two active sites with a binding energy of –41 kJ mol−1, which corresponds to the spontaneous formation of chemisorbed and physisorbed species. When AsV flowed over the BSA/hematite film, only 11 % of surface BSA was desorbed by AsV. This result highlights the inhibitory effect of BSA for AsV adsorption. Structural analysis of BSA revealed changes to the local conformational geometry upon adsorption to and desorption from hematite nanoparticles. Molecular docking simulations showed that the binding free energy of a modelled hematite nanoparticle towards the BSA surface is –6.8 kcal mol−1 (−28.5 kJ mol−1) owing to the formation of various bonds, which agrees with the adsorption kinetics modelling. Overall, surface BSA inhibits arsenate adsorption and therefore increases its mobility and bioavailability.\u0000","PeriodicalId":11714,"journal":{"name":"Environmental Chemistry","volume":"2 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2021-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81626107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
