Nitrogen and nitrogen oxides

Medicine, 2003
Abstract Evaporation of liquid nitrogen from the eye or skin may cause cold burns. It may displace oxygen, causing hypoxic asphyxia. Of the nitrogen oxides NO 2 is most toxic. Following exposure, effects in the peripheral airways and alveoli can be expected; clinical symptoms are usually absent during the first hours after exposure.

Nitrogen-Inorganic Forms

SSSA Book Series, 2018
Most soils contain inorganic nitrogen (N) in the form of ammonium (NHt) and nitrate (NO)"). Nitrite (NOz) also may be present, but the amount is usually too small to warrant its determination, except in cases where NHt or NHt-forming fertilizers are ...

Abating ammonia is more cost-effective than nitrogen oxides for mitigating PM2.5 air pollution

Science, 2021
Description Little things matter Particulate air pollution 2.5 micrometers or smaller in size (PM2.5) is a major cause of human mortality, and controlling its production is a health policy priority. Nitrogen oxides are an important precursor of PM2.5 and

Nitrogen Footprints

2019
N is one of essential element of life on earth, but it contributes in its reactive form to the global environmental problems that are already larger than our earth is able to cope with, and it expected further aggravate (Galloway and Leach, 2016) driven by the increasing demand of food products fuelled by growth of human population, rising incomes and ...

An Update on the Nitrogen Heterocycle Compositions and Properties of U.S. FDA-Approved Pharmaceuticals (2013-2023).

Journal of Medicinal Chemistry
This Perspective is a continuation of our analysis of U.S. FDA-approved small-molecule drugs (1938-2012) containing nitrogen heterocycles. In this study we report drug structure and property analyses of 321 unique new small-molecule drugs approved from ...

Nitrogen-Nitrogen Elastic Scattering

Physical Review, 1958
An optical-model analysis of the measurements of nitrogen-nitrogen elastic scattering is made, and a quasi-classical discussion of the corresponding phase shifts is given. (auth)
