Nitrogen is present in the environment in a wide variety of chemical forms including organic nitrogen, ammonium (NH + 4), nitrite (NO − 2), nitrate (NO − 3), nitrous oxide (N 2 O), nitric oxide (NO) or inorganic nitrogen gas (N 2). Organic nitrogen may be in the form of a living organism, humus or in the intermediate products of organic ...
In its natural state, nitrogen exists primarily as a gas (N2) in the atmosphere, making up about 78% of the air we breathe. Nitrogen finds extensive usage across various sectors, primarily in the agriculture industry, and transportation. Its versatility stems from its ability to form numerous compounds, each with unique properties and applications.
Louisiana will resume executions after a 15-year hiatus, forging ahead on plans set in motion last spring to carry out death sentences using nitrogen hypoxia. The office of Louisiana Gov. Jeff ...
Environmental impact: Generating nitrogen gas by PSA is a sustainable, environmentally friendly and energy efficient approach to providing pure, clean, dry nitrogen gas. Compared to the energy needed for a cryogenic air separation plant and the energy needed to transport the liquid nitrogen from the plant to the facility, generated nitrogen ...
ATMORE, Ala. — Alabama is poised to use nitrogen gas in a planned execution next month, the first state to attempt such a method, setting the stage for legal challenges as officials across the U ...

Human impact on the nitrogen cycle is diverse. Agricultural and industrial nitrogen (N) inputs to the environment currently exceed inputs from natural N fixation. [1] As a consequence of anthropogenic inputs, the global nitrogen cycle (Fig. 1) has been significantly altered over the past century.
Nitrogen forms and pathways within an agricultural production system. Nitrogen is a common element in nature and an essential plant nutrient. Approximately 78% of Earth's atmosphere is nitrogen (N 2). The strong bond between the atoms of N 2 makes this gas quite inert and not directly usable by plants and animals. As nitrogen naturally cycles ...
