  2. 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]

  3. Ozone and biology - Wikipedia

    en.wikipedia.org/wiki/Ozone_and_biology

    Delivering ozone dissolved in liquids is not straight forward as ozone gas has limited solubility in water or oil. [15] When treating the water or other liquids themselves, the solubility is less of a problem as pure ozone gas can be discharged into the liquid until the desired effect is achieved.

  4. Ozone - Wikipedia

    en.wikipedia.org/wiki/Ozone

    For the last few decades, scientists studied the effects of acute and chronic ozone exposure on human health. Hundreds of studies suggest that ozone is harmful to people at levels currently found in urban areas. [78] [79] Ozone has been shown to affect the respiratory, cardiovascular and central nervous system. Early death and problems in ...

    They also emphasize that for ozone to be effective as a germicide, it must be present at concentrations far greater than can be safely tolerated by humans or other animals. [18] More recent reviews have highlighted that different routes of administration may result in different therapeutic and side-effect profiles. [19]

    Effects of ozone The smog (of which ozone is a main ingredient) that afflicts the two national parks in the southern Sierra Nevada rises up from the Valley floor with the prevailing winds.

  7. Air pollution - Wikipedia

    en.wikipedia.org/wiki/Air_pollution

    An air pollutant is a material in the air that can have many effects on humans and the ecosystem. [61] The substance can be solid particles, liquid droplets, or gases, and often takes the form of an aerosol (solid particles or liquid droplets dispersed and carried by a gas). [ 62 ]

    Both types of ozone depletion were observed to increase as emissions of halocarbons increased. Ozone depletion and the ozone hole have generated worldwide concern over increased cancer risks and other negative effects. The ozone layer prevents harmful wavelengths of ultraviolet (UVB) light from passing through the Earth's atmosphere.

  9. Ozone depletion and climate change - Wikipedia

    Ozone is a greenhouse gas, [32] and changes in its atmospheric abundance due to human activity have radiative forcing effects. Ozone absorbs both ultraviolet (UV) radiation from the sun and infrared radiation emitted from Earth's surface. [4]
