Rolul nutrienților în poluarea difuză a corpurilor de apă din bazinul hidrografic Răut

Abstract

The amount of organic substance, nutrients (nitrogen and phosphorus) from diffuse sources in the Răut Hydrographic Basin was evaluated. It was found that out of total nitrogen, 66% is produced by livestock, 29% is formed in human agglomerations, and 5% is nitrogen from household waste. Phosphorus is produced by livestock -46%, by agglomerations of -49% and by 5% of household waste. The spatial distribution of nutrients on small river basins is relatively uniform. The major risk for water bodies in the BHR not to achieve a "good environmental status", under the Water Framework Directive, is current land use, in particular the weight and management of agricultural land.
