Nitrous oxide sources - Tropical Soils
Our rapidly increasing use of nitrogen based fertilizers on tropical soils is giving rise to ballooning nitrous oxide emissions from this source. Additionally, increased atmospheric nitrogen deposition due to man-made nitrogen emissions, such as intensive livestock rearing, can induce elevated rates of nitrous oxide emission over large areas of otherwise untouched tropical soil. Rates of nitrous ...

Nitrous oxide sources - Temperate soils
Our increased use of nitrogen based fertilizers in recent decades has given rise to much increased nitrous oxide emissions from temperate soils. Additionally, increased atmospheric nitrogen deposition due to man-made nitrogen emissions, such as intensive livestock rearing, can induce elevated rates of nitrous oxide emission over large areas of otherwise natural temperate soil. As with tropical ...

Human Impact Through widespread land drainage and changes in land-use, man has had a great impact on wetland methane emissions in many areas of the world. Additionally, increased nitrogen deposition from the atmosphere, again resulting from human activity, may also greatly increase net methane emissions from wetland areas by inhibiting any methane consumption (methane oxidation). Potential for ...

Air Pollution
However, despite this, deposition of atmospheric pollutants as well as exposure to high concentrations of pollutants represent a significant threat to sensitive ecosystems. In particular, nitrogen deposition and elevated concentrations of ground-level ozone are priority concerns. The review prepared by the National Expert Group on Transboundary Air Pollution provides a comprehensive account of ...
