A retrospective cohort study on red blood cell morphology changes in pre-school age children under nitrous oxide anesthesia

BMC Anesthesiology, 2021
Background Megaloblastic anemia or bone marrow changes could occur after prolonged nitrous oxide inhalation via vitamin B12 inactivation related DNA synthesis impairment. Previous researches have studied hematological changes with nitrous oxide exposure,

High nitrous oxide emissions from temporary flooded depressions within croplands

Communications Earth & Environment, 2023
Nitrous oxide is an important greenhouse gas and emissions from managed ecosystems are directly correlated to anthropogenic nitrogen input. Here we have measured nitrous oxide emissions from flooded depressions within croplands and from incubated soil ...

An intercomparison of oceanic methane and nitrous oxide measurements [PDF]

Biogeosciences, 2018
Large-scale climatic forcing is impacting oceanic biogeochemical cycles and is expected to influence the water-column distribution of trace gases, including methane and nitrous oxide.

A standardised method for measuring in situ denitrification in shallow aquifers: numerical validation and measurements in riparian wetlands [PDF]

, 2003
A tracer test to examine in situ denitrification in shallow groundwater by a piezometer with a packer system used bromide as a tracer of dilution and acetylene (10%) to block the denitrification process at the nitrous oxide stage.

Niche differentiation in nitrogen metabolism among methanotrophs within an operational taxonomic unit [PDF]

, 2014
Background: The currently accepted thesis on nitrogenous fertilizer additions on methane oxidation activity assumes niche partitioning among methanotrophic species, with activity responses to changes in nitrogen content being dependent on the in situ ...
