The anthropogenic nitrogen cycle in the Netherlands

摘要: Results of a study on the nitrogen flows in Netherlands are presented for three different years. The details given 1995 preliminary. data derived from material balance sheet investigation. objective is to present complete, integrated and accurate overview losses anthropogenic cycle country with respect possible future nitrous oxide emissions. Losses analyzed terms economic sources recipient environmental compartments. account about 25% total input cycle. Most occur agriculture (67%), whereas industry, traffic households each contribute 10% loss. About 15% national economy ends up environment, where it gives rise adverse effects as eutrophication fresh surface water contamination ground nitrate. A comparison results years shows that little progress has been made emission reductions so far. Ammonia emissions have reduced, but at expense an increase agricultural soils.
