Upstream silver source mapping - a case study in Stockholm, Sweden.

Due high accumulation rate in soils, the levels of Ag incoming water at WWTP must reduced. This study aims identify major diffuse emission sources technosphere through comprehensive substance flow analysis Stockholm, Sweden. Large inflows stocks were present electrical electronic goods appliances well jewellery silverware. The total inflow was 3.2 tonnes (4.2 g/person), stock 100 (140 g/person) outflow 330 kg (430 mg/person). Major identified with emissions ending up (total 26 kg, 34 mg/person) food, amalgam beauty products (via urine faeces, 12 mg/person or 11% amount), textiles washing, 17 16% amount). explains approximately 35% 80 Henriksdal Stockholm.
