| Tiivistelmä: | The mobilization of phosphorous (P), a nonrenewable resource that is not fully recycled biologically or industrially, has been quadrupled by human activity. P is accumulated in both water and solid waste due to fertilizer application and industrial, agricultural and animal P consumption. This article characterizes the industrial flows, which, although smaller than the agricultural and animal flows, are an important phosphorous source contributing to the pollution of surface waters. This study presents the quantification of the network of flows as constrained by mass balances of the global consumption for 2004, all of which eventually ends up as waste and in the soil and water systems. |
