  2. Ozone and biology - Wikipedia

    en.wikipedia.org/wiki/Ozone_and_biology

    Ozone's effect on signalling in animals may therefor become more significant than its direct affect as an antibiotic at higher concentrations. [8] Developments of techniques capable of more accurately monitoring ozone levels inside cells will enable investigation of endogenous ozone in cells, perhaps clarifying how cells use endogenous ozone.

  3. Ozone depletion - Wikipedia

    en.wikipedia.org/wiki/Ozone_depletion

    Ozone depletion would magnify all of the effects of UV on human health, both positive (including production of vitamin D) and negative (including sunburn, skin cancer, and cataracts). In addition, increased surface UV leads to increased tropospheric ozone, which is a health risk to humans. [62]

  4. Ozone depletion and climate change - Wikipedia

    Ozone depletion is not a primary cause of climate change, however there exists a physical science connection between the two phenomena. The Earth's atmospheric ozone has two major effects on the Earth's temperature balance. Firstly, it absorbs solar ultraviolet radiation, leading to the heating of the stratosphere.

    Short-term effects of exposure to smoke tend to appear in both the upper and lower airways, with the nose screening out a lot of larger particles and then the lungs acting as “a first responder ...

    en.wikipedia.org/wiki/Ozone

    Ground-level ozone, or tropospheric ozone, is the most concerning type of ozone pollution in urban areas and is increasing in general. [60] Ozone pollution in urban areas affects denser populations, and is worsened by high populations of vehicles, which emit pollutants NO 2 and VOCs, the main contributors to problematic ozone levels. [61]

  7. Effects of climate change on human health - Wikipedia

    en.wikipedia.org/wiki/Effects_of_climate_change...

    The effects of climate change on human health are profound because they increase heat-related illnesses and deaths, respiratory diseases, and the spread of infectious diseases. There is widespread agreement among researchers, health professionals and organizations that climate change is the biggest global health threat of the 21st century.

  8. Ground-level ozone - Wikipedia

    en.wikipedia.org/wiki/Ground-level_ozone

    Reaction with daylight ultraviolet (UV) rays and these precursors create ground-level ozone pollution. Ozone is known to have the following health effects at concentrations common in urban air: Irritation of the respiratory system, causing coughing, throat irritation, and/or an uncomfortable sensation in the chest.

  9. Air pollution - Wikipedia

    en.wikipedia.org/wiki/Air_pollution

    Schematic drawing, causes and effects of air pollution: (1) greenhouse effect, (2) particulate contamination, (3) increased UV radiation, (4) acid rain, (5) increased ground-level ozone concentration, (6) increased levels of nitrogen oxides. An air pollutant is a material in the air that can have many effects on humans and the ecosystem. [61]
