  2. Nitrogen dioxide poisoning - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_dioxide_poisoning

    Nitrogen dioxide poisoning is the illness resulting from the toxic effect of nitrogen dioxide (NO 2). It usually occurs after the inhalation of the gas beyond the threshold limit value. [1] Nitrogen dioxide is reddish-brown with a very harsh smell at high concentrations, at lower concentrations it is colorless but may still have a harsh odour.

  3. NOx - Wikipedia

    en.wikipedia.org/wiki/NOx

    Nitrogen oxides are released during manufacturing of nitrogen fertilizers. Though nitrous oxide is emitted during its application, it is then reacted in atmosphere to form nitrogen oxides. This third source is attributed to the reaction of atmospheric nitrogen, N 2 , with radicals such as C, CH, and CH 2 fragments derived from fuel, [ 26 ...

  4. Nutrient pollution - Wikipedia

    en.wikipedia.org/wiki/Nutrient_pollution

    Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrients.It is a primary cause of eutrophication of surface waters (lakes, rivers and coastal waters), in which excess nutrients, usually nitrogen or phosphorus, stimulate algal growth. [1]

  5. Decompression sickness - Wikipedia

    en.wikipedia.org/wiki/Decompression_sickness

    [17] [35] This is because nitrogen is five times more soluble in fat than in water, leading to greater amounts of total body dissolved nitrogen during time at pressure. Fat represents about 15–25 percent of a healthy adult's body, but stores about half of the total amount of nitrogen (about 1 litre) at normal pressures. [50]

  6. Human impact on the nitrogen cycle - Wikipedia

    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.

  7. Air pollution - Wikipedia

    en.wikipedia.org/wiki/Air_pollution

    Nitrogen dioxide is a chemical compound with the formula NO 2. It is one of several nitrogen oxides. One of the most prominent air pollutants, this reddish-brown toxic gas has a characteristic sharp, biting odor. Odors: Such as from garbage, sewage, and industrial processes.

  8. What is nitrogen hypoxia? Alabama’s untested execution method ...

    The use of nitrogen hypoxia has been the subject of delays in Alabama that have focused not on whether it is inhumane, but logistical issues of how it would be administered.

  9. Leaching (agriculture) - Wikipedia

    en.wikipedia.org/wiki/Leaching_(agriculture)

    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 ...
