Masculinities and femininities of drinking in Finland,Italy and Sweden: Doing,modifying and unlinking gender in relation to different drinking places     

《Geoforum》2017

In this article we analyze how Finnish, Italian and Swedish men and women are doing, modifying and unlinking gender in relation to different drinking places and situations. In the study, Finland and Sweden represent the Nordic intoxication-oriented drinking cultures, whereas Italy, in turn, represents the Mediterranean meal drinking cultures. The data were collected in a similar way in Finland, Italy and Sweden from 2007 to 2010, covering four different age groups. From each country at least eight male and eight female groups were selected, i.e. two male and two female groups from each age group, one representing higher and the other lower social status professions. All focus groups were asked to interpret a set of pictures representing different kinds of drinking places and situations, such as a couple’s moderate wine drinking at a sidewalk table, heavy drinking among men in a bus, and playful drinking among women while dancing. In the analysis we emphasize the flexibility of doing gender and the possibility of challenging conventional gender performances. We assume that doing gender is a multi-dimensional process mediated by structures, hierarchies, identities, situations and agency. Our analysis presents a mosaic repertoire of masculinities and femininities that change shape depending on how the place is seen in terms of a drinking space or situation. The masculinities and femininities are not reducible to any single hierarchy of dominant and subordinate masculinities and femininities. Rather, the doing, modifying and unlinking of masculinities and femininities vary by geographical area, age and/or education, as well as by drinking situation.  相似文献

Biodegradation of NOM in Rapid Sand Filters for Removing Iron and Manganese     

Andreas Korth  Bernd Bendinger  Christoph Czekalla  Knut Wichmann 《洁净——土壤、空气、水》2001,29(5):289-295

In order to examine the Corg flow in rapid sand filter columns for the elimination of iron and manganese, reduced groundwater was treated in a pilot plant consisting of a trickling filter column (TF I) followed by a wet type filter column (WF II) and a separate wet type filter column (WF sep). Additionally the effect of filtration on BOM was studied by measuring AOC and BDOC. The biological processes in TF I and WF sep led to an elimination of iron, ammonia, and manganese. Moreover, the filtration decreased the NOM content. 21% and 23% of the TOC were eliminated in TF I and in WF sep, respectively. WF II caused no significant Corg reduction. The calculation of the Corg flow in the filter columns showed that bacteria took part in the TOC elimination. From the TOC removed, about 24% was eliminated by metabolic activities of the bacterial population whereas 86% was adsorbed onto iron sludge. Similar results were obtained for the TF I column and for the WF sep column as well. The calculated Corg flow was confirmed by the BDOC measurements. The filtration process led to a BDOC decrease. TF I and WF sep reduced appoximately 35% of the biodegradable organic carbon. In contrast there was no significant elimination by WF II. The AOC results suggest that an AOC production and an AOC elimination process exist in rapid sand filters for groundwater treatment. In the trickling filter column significant AOC production was found, whereas in the wet type filter columns AOC elimination was predominating.  相似文献   

Electrodialytic Defluoridation of Brackish Water: Effect of Process Parameters and Water Characteristics     

Mourad Ben Sik Ali  Bchir Hamrouni  Mahmoud Dhahbi 《洁净——土壤、空气、水》2010,38(7):623-629

The aim of this work is to study the removal of fluoride from brackish polluted water using electrodialysis. The influence of several parameters such as flow rate, initial feed concentration, co‐existing ions, and initial pH on process efficiency were studied. This efficiency is evaluated by the removal rate, demineralization rate, and power consumption. The defluoridation process showed to be independent of pH of feed solution. Although the remained studied parameters plays a significant role on the defluoridation efficiency and mainly on the specific power consumption. The defluoridation of a contaminated real water sample was investigated so as to improve the efficiency of the process. The fluoride concentration could be reduced from 2.9 to 0.4 mg L⁻¹ which was lower than World Health Organization (WHO) standard (1.5 mg L⁻¹). Moreover the concentrations of different species in the obtained treated water are below the amounts recommended by WHO for drinking water.  相似文献

Preconcentration of trace multi-elements in water samples using Dowex 50W-x8 and Chelex-100 resins prior to their determination using inductively coupled plasma atomic emission spectrometry (ICP-OES)     

《Physics and Chemistry of the Earth》2013

This work presents a solid phase extraction (SPE) method for simultaneous preconcentration of trace elements in water samples prior to their ICP-OES determination. Dowex 50W-x8 and Chelex-100 resins were used as SPE sorbent materials for preconcentration of trace Cd, Co, Cr, Cu, Fe, Ni, Pb and Zn. The optimum sample pH, eluent concentration and sample flow rates were found to 6, 3.0 mol L⁻¹ and 3.0 mL min⁻¹, respectively. In terms of multi-element preconcentration capabilities, Dowex 50W-x8 appeared to be a better sorbent. The recoveries for all the tested analytes were >95%. However, Chelex-100 showed a better performance in terms of recovery (>95%) towards Cu, Fe and Zn. Under optimized conditions using Dowex 50W-x8, the relative standard deviations for different metals were <3%. The limits of detection and limits of quantification ranged from 0.01–0.39 μg L⁻¹ and 0.05–0.1.3 μg L⁻¹, respectively. The accuracy of the preconcentration method was confirmed by spike recovery test and the analysis of certified reference materials. The SPE method was applied for preconcentration of the analyte ions in tap water, bottled water and wastewater samples.  相似文献   

Minor effect of beaver dams on stream dissolved organic carbon in the catchment of a German drinking water reservoir     

《Limnologica》2016

Rising concentrations of dissolved organic carbon (DOC) are negatively affecting the water quality in several drinking water reservoirs. The presence of beaver dams can influence surface water quality on a catchment scale. In recent years, beavers have been re-introduced in numerous locations in Central Europe. We investigated whether the presence of beaver dams in the catchment of a German drinking water reservoir impacts DOC quantity and quality in the streams entering the Wehebach reservoir in Germany.By comparing water quality upstream and downstream of beaver dams during three low discharge situations we did not find a significant effect of dams both on DOC quantity and quality. The analysis of long term monitoring data at the gauges showed that beaver dams had a negligible effect on the DOC load to the reservoir. DOC quantity was closely linked to iron concentration in the streams. Co-precipitation with iron minerals was an effective process removing DOC from the stream-water. By analyzing fluorescence excitation emission indices we show that beaver dams did not have a clear effect on DOC quality. We conclude that the presence of beaver dams has only small effects on water quality and is not a problem for water quality in the downstream drinking water reservoir.  相似文献

Hydrochemical characteristics and seasonal variations in groundwater quality of an alluvial aquifer in parts of Central Ganga Plain,Western Uttar Pradesh,India   总被引：1，自引：0，他引：1  

Rashid Umar  Izrar Ahmed  Fakhre Alam  Mohammad Muqtada Khan 《Environmental Geology》2009,58(6):1295-1300

The present study was undertaken to assess major ion chemistry of groundwater in parts of the Central Ganga Plain and observe seasonal variations in its chemical quality. Systematic sampling was carried out during November 2005 and June 2006. The major ion chemistry of groundwater shows large variations, so much so that at times the meteoric signature seems to be completely obliterated. In many samples the concentrations of SO₄, NO₃ and F are above the permissible limit for human consumption. The graphical treatment of major ion chemistry helps in identifying four types of groundwater. All possible ionic species such as NaCl, KCl, NaHCO₃, NaSO₄, KNO₃, NaNO₃, CaHCO₃, MgHCO₃, MgSO₄ are likely to occur in groundwater system. The observed chemical variations may be attributed to sediment water interaction, ion exchange, dissolution mechanisms and anthropogenic influences such as application of fertilizers and effluents from sugar factories and paper mills. A general increase in TDS is observed in samples during June 2006. The increase in salinity is attributed to evaporation from water table, irrigation return flows, anthropogenic activities and below average rainfall in 2005 and 2006.
