  2. Ozone - Wikipedia

    en.wikipedia.org/wiki/Ozone

    Ozone does not form organochlorine compounds, nor does it remain in the water after treatment. Ozone can form the suspected carcinogen bromate in source water with high bromide concentrations. The U.S. Safe Drinking Water Act mandates that these systems introduce an amount of chlorine to maintain a minimum of 0.2 μmol/mol residual free ...

  3. Ground-level ozone - Wikipedia

    en.wikipedia.org/wiki/Ground-level_ozone

    The IPCC believes that "measured stratospheric O3 losses over the past two decades have generated a negative forcing of the surface-troposphere system" of around 0.15 0.10 watts per square metre (W/m 2). [39] Furthermore, rising air temperatures often improve ozone-forming processes, which has a repercussion on climate, as well.

  4. Body of water - Wikipedia

    en.wikipedia.org/wiki/Body_of_water

    A body of frozen water more than 50,000 km 2: Inlet: a body of water, usually seawater, which has characteristics of one or more of the following: bay, cove, estuary, firth, fjord, geo, sea loch, or sound. Kettle (or kettle lake) a shallow, sediment-filled body of water formed by retreating glaciers or draining floodwaters. Kill

  5. Ozone and biology - Wikipedia

    en.wikipedia.org/wiki/Ozone_and_biology

    Ozone cycle illustrated over image by NASA astronaut Scott Kelly. Ozone is a ubiquitous yet highly reactive molecule in the atmosphere. Such a highly reactive oxidizer would normally be dangerous to life but ozone's concentration at sea level is usually not high enough to be toxic.

  6. Dead zone (ecology) - Wikipedia

    en.wikipedia.org/wiki/Dead_zone_(ecology)

    Red circles show the location and size of many dead zones (in 2008). Black dots show dead zones of unknown size. The size and number of marine dead zones—areas where the deep water is so low in dissolved oxygen that sea creatures cannot survive (except for some specialized bacteria)—have grown in the past half-century.

  7. Outline of water - Wikipedia

    Groundwater – Water located beneath the ground surface; Body of water – Any significant accumulation of water, generally on a planet's surface Salt waterWater that contains a high concentration of dissolved salts Seawater – Water from a sea or an ocean; Ocean – Body of salt water covering most of Earth

  8. Trioxidane - Wikipedia

    en.wikipedia.org/wiki/Trioxidane

    The reverse reaction, the addition of singlet oxygen to water, typically does not occur in part due to the scarcity of singlet oxygen. In biological systems, however, ozone is known to be generated from singlet oxygen, and the presumed mechanism is an antibody-catalyzed production of trioxidane from singlet oxygen.

  9. Anoxic waters - Wikipedia

    en.wikipedia.org/wiki/Anoxic_waters

    The temperature of a body of water directly affects the amount of dissolved oxygen it can hold. Following Henry's law, as water becomes warmer, oxygen becomes less soluble in it. This property leads to daily anoxic cycles on small geographic scales and seasonal cycles of anoxia on larger scales.
