About 1900 m2 grassland per capita are needed to supply Austrians population with the currently required amounts of food. In total, these are 420m2 of arable land per capita more than available in Austria. By contrast, Austria has 440m2 of grassland per capita more than required for food supply of the own population. Our calculations show that 19.5kgNcapita−1    year−1 are needed from external sources for agricultural production. Out of this, 71% of the nitrogen (N) input and 58% of the phosphorus (P) input into the agricultural system is used for fodder production, the rest for production of plant based food and products for industrial use. Furthermore animal husbandry is responsible for 46% of the total N and 28.5% of the total P emissions into surface water in Austria, production of plant based food and of industrial products for 3.2% and 2.3%, respectively. The rest of emission is related to waste water disposal and air pollution. With regards to water consumption, calculated as water footprint, animal husbandry is responsible for 87% of the total food production induced water footprint.</div>","PeriodicalId":101194,"journal":{"name":"Sustainability of Water Quality and Ecology","volume":"1 ","pages":"Pages 24-39"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.swaqe.2014.04.003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87743271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comparison of four interpolation techniques (ordinary kriging, simple kriging, inverse distance weighted and local polynomial interpolation) via cross validation suggested that kriging was the most accurate spatial analysis technique for the majority of the elements. Variogram models obtained by geostatistical procedures indicate existence of spatial correlation between samples, with the exceptions for Al, Cd and Zn. The mapped spatial distributions are showing a clear coincidence of variation pattern for different groups of the heavy metals. This indicates similar origin and affecting factors for these analyzed metals. Possible anthropogenic and natural sources of heavy metals were discussed based on the distribution maps and correlation analysis with other elements and geologic units. The results have shown that the accurate spatial pattern of heavy metals could improve our understanding of possible sources, controlling factors and involving processes. This is essential for monitoring and remediation of the contaminant sites in the watershed.</div>","PeriodicalId":101194,"journal":{"name":"Sustainability of Water Quality and Ecology","volume":"1 ","pages":"Pages 48-58"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.swaqe.2014.04.002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72722753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that water samples drawn from just-treated water prior to its distribution to the supply occasionally contained above allowed levels of pathogen counts. Water samples at consumer points along the supply line contained fluctuations of total and faecal coliform counts with significant high counts during rainy season. Owing to sprawling human settlements and various urban construction and industrialization, interference with the natural drainage system is increasingly creating effluents significant pathogen and other pollutants into the water system, with concomitant implications on the efficacy of their removal from the city drinking water supply. Pathogen levels and the by-products of chlorinating water and associated health implications are discussed in light of public health, cost effectiveness and sustainability. Optimal levels of chlorine in water supply line and low faecal coliform bacteria concentration are important criteria for protecting water quality.</div>","PeriodicalId":101194,"journal":{"name":"Sustainability of Water Quality and Ecology","volume":"1 ","pages":"Pages 59-67"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.swaqe.2014.04.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87815141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
