Examples of nitrous oxide

• Most patients were intubated and anesthetized with nitrous oxide and oxygen during catheterization.

• Nitrogen losses as ammonia and nitrous oxide are also undesirable due to their environmental impacts.

• Effect of straw addition on nitrous oxide and methane emissions from stored farmyard manures.

• They have been applied in sub-anaesthetic concentration, both individually and in combination with nitrous oxide, for pain relief in labour.

• Nitrous oxide and methane emissions following application of animal manures to grassland.

• Sources of nitric oxide and nitrous oxide following wetting of dry soil.

• Denitrification of leached nitrate accounted for 26-35% of nitrous oxide emissions.

• The editors move on more briefly to methane, and then to nitrous oxide, before wrapping up with some thoughts on interactions.
