  2. 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]

  3. Nitrate vulnerable zone - Wikipedia

    en.wikipedia.org/wiki/Nitrate_vulnerable_zone

    A nitrate vulnerable zone is a conservation designation of the Environment Agency for areas of land that drain into nitrate polluted waters, or waterways that could become polluted by nitrates due to environmental and health threats. A nitrate vulnerable zone can be designated as a response to an increase in nitrate leaching or increased use of ...

  4. Peroxyacyl nitrates - Wikipedia

    en.wikipedia.org/wiki/Peroxyacyl_nitrates

    In organic chemistry, peroxyacyl nitrates (also known as Acyl peroxy nitrates, APN or PANs) are powerful respiratory and eye irritants present in photochemical smog. They are nitrates produced in the thermal equilibrium between organic peroxy radicals by the gas -phase oxidation of a variety of volatile organic compounds (VOCs), or by aldehydes ...

  5. Nitrate - Wikipedia

    en.wikipedia.org/wiki/Nitrate

    In the NO − 3 anion, the oxidation state of the central nitrogen atom is V (+5). This corresponds to the highest possible oxidation number of nitrogen. Nitrate is a potentially powerful oxidizer as evidenced by its explosive behaviour at high temperature when it is detonated in ammonium nitrate (NH 4 NO 3), or black powder, ignited by the shock wave of a primary explosive.

  6. List of pollution-related diseases - Wikipedia

    en.wikipedia.org/wiki/List_of_pollution-related...

    This is in part because pollution causes so many diseases that it is often difficult to draw a straight line between cause and effect. There are many types of pollution-related diseases, including those caused by air pollution , contaminated soil , water pollution and lacking water, sanitation and hygiene (WASH) .

  7. Biogeochemical cycle - Wikipedia

    en.wikipedia.org/wiki/Biogeochemical_cycle

    There is also evidence for shifts in the production of key intermediary volatile products, some of which have marked greenhouse effects (e.g., N 2 O and CH 4, reviewed by Breitburg in 2018, [15] due to the increase in global temperature, ocean stratification and deoxygenation, driving as much as 25 to 50% of nitrogen loss from the ocean to the ...

  8. Human impact on the environment - Wikipedia

    en.wikipedia.org/.../Human_impact_on_the_environment

    An indicator reflecting the loss of nitrate to groundwater would be effect-based. [51] The environmental impact of agriculture involves a variety of factors from the soil, to water, the air, animal and soil diversity, plants, and the food itself.

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

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

    Nitrogen leaching occurs when nitrogen compounds, primarily nitrates, move through the soil profile and enter groundwater, potentially contaminating drinking water sources. [2] To mitigate these environmental impacts, various nitrogen management strategies are employed in agriculture.
