Global land–ocean linkage: direct inputs of nitrogen to coastal waters via submarine groundwater discharge

The role of submarine groundwater discharge (SGD), the leakage of groundwater from aquifers into coastal waters, in coastal eutrophication has been demonstrated mostly for the North American and…

Exploring global nitrogen and phosphorus flows in urban wastes during the twentieth century

This paper presents a global model-based country-scale quantification of urban nitrogen (N) and phosphorus (P) waste flows from humans, animals, and industries, including discharge to surface water…

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…

Climate impact of transportation A model comparison

Transportation contributes to a significant and rising share of global energy use and greenhouse gas emissions. Therefore modeling future travel demand, its fuel use, and resulting CO 2 emission is…

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…

Our Nutrient World

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 Role of Nitrate in Human Health

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…
