The global nitrogen cycle in the twenty-first century
Global nitrogen fixation contributes 413 Tg of reactive nitrogen (Nr) to terrestrial and marine ecosystems annually of which anthropogenic activities are responsible for half, 210 Tg N. The majority…
European scenarios for exposure of soil organisms to pesticides
Standardised exposure scenarios play an important role in European pesticide authorisation procedures (each scenario is a combination of climate, weather and crop data to be used in exposure models)…
Hindcasts and Future Projections of Global Inland and Coastal Nitrogen and Phosphorus Loads Due to Finfish Aquaculture
A global model is used to calculate feed and nutrient budgets for freshwater and marine omnivorous and carnivorous aquacultural finfish production. The model uses national production data for the…
Costs and Benefits of Nitrogen for Europe and Implications for Mitigation
Cost-benefit analysis can be used to provide guidance for emerging policy priorities in reducing nitrogen (N) pollution. The results support the priority for further reduction in NH 3 and NO x…
A new report commissioned by the United Nations Environment Programme (UNEP) highlights how humans have massively altered the natural flows of nitrogen, phosphorus and other nutrients. While this has…
The EU and the World Health Organization apply a drinking water standard for nitrate in drinking water of 50 milligrams per litre. The risks to human health posed by nitrate in drinking water have…
Exploring global Cryptosporidium emissions to surface water
The protozoan parasite Cryptosporidium is a major cause of diarrhea worldwide. This paper presents the first model-based inventory with 0.5 by 0.5 degree resolution of global Cryptosporidium emissions…
Management, regulation and environmental impacts of nitrogen fertilization in north-western Europe under the Nitrates Directive; a benchmark study
Implementation of the EU Nitrates Directive and its environmental impacts were compared for Member States in the north-west of the European Union (Ireland, United Kingdom, Denmark, the Netherlands…
Reform of the EU Common Agricultural Policy: Environmental impacts in developing countries
The proposed reform of the Common Agricultural Policy (CAP) will have little impact in developing countries. This is the conclusion by the PBL Netherlands Environmental Assessment Agency…
European-scale modelling of groundwater denitrification and associated N2O production
This paper presents a spatially explicit model for simulating the transport of nitrogen (N) and the denitrification and associated production of nitrous oxide (N 2 O) in groundwater, with a one…
