Significance of urban and agricultural land use for biocide and pesticide dynamics in surface waters
Irene Wittmer,Heinz Bader,Ruth Scheidegger,Heinz Singer,Alfred Lück,Irene Hanke,C. Carlsson,Christian Stamm +7 more
TL;DR: It can be safely concluded that in catchments of mixed land use, the contributions of biocide and pesticide inputs into surface waters from urban areas are at least as important as those from agricultural areas.
Journal ArticleDOI
Key drivers of the e-waste recycling system: Assessing and modelling e-waste processing in the informal sector in Delhi
Martin Streicher-Porte,Rolf Widmer,Amit Jain,Hans-Peter Bader,Ruth Scheidegger,Susanne Kytzia +5 more
TL;DR: The study revealed that the life span of a personal computer has considerable influence upon the system, most notably in the following two aspects: (i) a prolonged life span creates value by means of refurbishing and upgrading activities, and (ii) it slows down the flow rate of the whole system.
Journal ArticleDOI
The Flow of Phosphorus in Food Production and Consumption : Linköping, Sweden, 1870-2000
TL;DR: The main changes in this system over time are the increasing flow of phosphorus reaching the consumer and hence the waste handling system, the increase in the flow of products from animal production, and most notably c) the increased input of chemical fertilizer.
Journal ArticleDOI
Modeling the contribution of point sources and non-point sources to Thachin River water pollution
TL;DR: The results show that aquaculture and rice farming are the key nutrient sources in the Thachin River Basin, and a comparison of simulated nutrient loads with measured nutrient concentrations shows that nutrient retention in the river system may be significant.
Journal ArticleDOI
Sustainable metal management exemplified by copper in the USA
TL;DR: In this paper, the authors used a set of data from the United States between 1900 and 2100 to illustrate mathematical modeling of the metal management system and found that the long-term copper consumption stock is greater than the short-term stock.
