Diffuse pollution

This work investigated the role of fertilizer application rate on phosphorus (P) transport and loading to Lake Uluabat in Turkey. For this purpose ArcView Interface of Soil and Water Assessment Tool 2000 (AVSWAT) was used. Results showed that when the fertilizer amount applied to agricultural lands

The enrichment of natural waters by nutrients from different sources has been associated with eutrophication in many Europe river basins. Materials accounting is a multidisciplinary approach to identify precisely the sources of pollution and to assess the most efficient preventive means to avoid the

This paper considers the importance of automobiles as a continuing source of persistent pollutants in the environment, using the UK as a case study. The mass of lead, copper, zinc and polycyclic aromatic hydrocarbons (PAHs) being released by automobiles in the UK is estimated. It is shown that as ot

Agricultural runoff contributes with significant amounts of nitrogen (N) to rivers and lakes causing water quality problems. Constructed wetlands (CWs) in first- and second-order streams reduce downstream loading of nutrients through mechanisms such as sedimentation, uptake by vegetation and microbi

Extensive effort through point source controls, such as the construction of wastewater treatment plants, has been continuously made not only to improve the water quality but also to protect the water resources since 1990 in the Han River basin, Korea. However, it is difficult to maintain biochemical
