  2. Ecological impact of explosives - Wikipedia

    en.wikipedia.org/.../Ecological_impact_of_explosives

    Ecological impacts of explosives are the effects that both unexploded explosives and post-explosion by-products have on the environment. [1] Explosive derived contaminants may have adverse effects on the environmental as well as human health. In addition to their military use in warfare, explosives are also used in construction and demolition.

  3. 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 ]

    Nutrient pollution caused by Surface runoff of soil and fertilizer during a rain storm 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 ...

  6. Contact explosive - Wikipedia

    en.wikipedia.org/wiki/Contact_explosive

    A contact explosive is a chemical substance that explodes violently when it is exposed to a relatively small amount of energy (e.g. friction, pressure, sound, light). Though different contact explosives have varying amounts of energy sensitivity , they are all much more sensitive relative to other kinds of explosives.

  7. Eutrophication - Wikipedia

    en.wikipedia.org/wiki/Eutrophication

    [17] [18] In marine ecosystems, nitrogen is the primary limiting nutrient; nitrous oxide (created by the combustion of fossil fuels) and its deposition in the water from the atmosphere has led to an increase in nitrogen levels, [19] and also the heightened levels of eutrophication in the ocean.

  8. Human impact on the nitrogen cycle - Wikipedia

    en.wikipedia.org/wiki/Human_impact_on_the...

    Freshwater acidification can cause aluminium toxicity and mortality of pH-sensitive fish species. Because marine systems are generally nitrogen-limited, excessive N inputs can result in water quality degradation due to toxic algal blooms, oxygen deficiency, habitat loss, decreases in biodiversity, and fishery losses. [8]

  9. Health and environmental impact of the petroleum industry

    en.wikipedia.org/wiki/Health_and_environmental...

    Combustion causes an increased amount of nitrous oxide, along with sulfur dioxide from the sulfur in the oil. These by-products combine with water in the atmosphere to create acid rain. The increased concentrations of nitrates and other acidic substances have significant effects on the pH levels of rainfall.
