  2. Human impact on the nitrogen cycle - Wikipedia

    NO 3 − may also be denitrified by bacteria, producing N 2, NO x, and N 2 O. Estimated nitrogen surplus (the difference between inorganic and organic fertilizer application, atmospheric deposition, fixation and uptake by crops) for the year 2005 across Europe. Human impact on the nitrogen cycle is diverse.

  3. Nitrogen and Non-Protein Nitrogen's effects on Agriculture

    en.wikipedia.org/wiki/Nitrogen_and_Non-Protein...

    High levels of ammonia resulting from the breakdown of NPN can disrupt rumen pH balance and microbial activity, leading to conditions such as rumen acidosis and ammonia toxicity. [12] Furthermore, excessive excretion of nitrogen in urine and feces from animals consuming diets high in NPN can contribute to nitrogen pollution in the environment.

  4. Bladder cancer - Wikipedia

    en.wikipedia.org/wiki/Bladder_cancer

    Bladder cancer is most common in wealthier regions of the world, where exposure to certain carcinogens is highest. It is also common in places where schistosome infection is common, such as North Africa. [56] Bladder cancer is much more common in men than women; around 1.1% of men and 0.27% of women develop bladder cancer. [2]

  5. Nitrification - Wikipedia

    en.wikipedia.org/wiki/Nitrification

    Nitrogen cycle. Nitrification is the biological oxidation of ammonia to nitrate via the intermediary nitrite.Nitrification is an important step in the nitrogen cycle in soil.The process of complete nitrification may occur through separate organisms [1] or entirely within one organism, as in comammox bacteria.

  6. Cancer survival rates - Wikipedia

    en.wikipedia.org/wiki/Cancer_survival_rates

    Several types of cancer are associated with high survival rates, including breast, prostate, testicular and colon cancer. Brain and pancreatic cancers have much lower median survival rates which have not improved as dramatically over the last forty years. [4] Indeed, pancreatic cancer has one of the worst survival rates of all cancers.

  7. Denitrification - Wikipedia

    en.wikipedia.org/wiki/Denitrification

    Soil pH and texture are both factors that can moderate denitrification, with higher pH levels driving the reaction more to completion. [22] Nutrient composition, particularly the ratio of carbon to nitrogen, is a strong contributor to complete denitrification, [ 23 ] with a 2:1 ratio of C:N being able to facilitate full nitrate reduction ...

  8. Cystectomy - Wikipedia

    en.wikipedia.org/wiki/Cystectomy

    Cystectomy is a medical term for surgical removal of all or part of the urinary bladder. It may also be rarely used to refer to the removal of a cyst. [1] The most common condition warranting removal of the urinary bladder is bladder cancer. [2] Two main types of cystectomies can be performed.

  9. Azotemia - Wikipedia

    en.wikipedia.org/wiki/Azotemia

    Azotemia (from azot 'nitrogen' and -emia 'blood condition'), also spelled azotaemia, is a medical condition characterized by abnormally high levels of nitrogen-containing compounds (such as urea, creatinine, various body waste compounds, and other nitrogen-rich compounds) in the blood.
