  2. Air quality guideline - Wikipedia

    en.wikipedia.org/wiki/Air_quality_guideline

    In terms of health effects, the guideline states that PM2.5 concentration of 10 is the lowest level at which total, cardiopulmonary and lung cancer mortality have been shown to increase with more than 95% confidence in response to long-term exposure to PM2.5. [2]

  3. Particulate pollution - Wikipedia

    en.wikipedia.org/wiki/Particulate_pollution

    However, there is no known safe level of exposure and thus, any exposure to particulate pollution is likely to increase an individual's risk of adverse health effects. [35] In European countries, air quality at or above 10 micrograms per cubic meter of air (μg/m 3 ) for PM 2.5 increases the all-causes daily mortality rate by 0.2-0.6% and the ...

  4. Brain health and pollution - Wikipedia

    en.wikipedia.org/wiki/Brain_health_and_pollution

    Exposure to air pollution was positively associated with an increased risk of stroke hospital admission (PM2.5, PM10, SO2, NO2, CO, and O3), incidence (PM2.5, SO2, and NO2), and mortality (PM2.5, PM10, SO2, and NO2). [60] There is a "well-recognized link between PM2.5 and vascular injury and the role of vascular injury in dementia". [61]

  5. List of countries by air pollution - Wikipedia

    The World Health Organization's recommended limit is 10 micrograms per cubic meter, although there are also various national guideline values, which are often much higher. Air pollution is among the biggest health problems of modern industrial society and is responsible for more than 10 percent of all deaths worldwide (nearly 4.5 million ...

  6. Air quality index - Wikipedia

    en.wikipedia.org/wiki/Air_quality_index

    On December 30, 2013, Hong Kong replaced the Air Pollution Index with a new index called the Air Quality Health Index. [17] This index, reported by the Environmental Protection Department, is measured on a scale of 1 to 10+ and considers four air pollutants: ozone; nitrogen dioxide; sulfur dioxide and particulate matter (including PM10 and PM2 ...

  7. Environmental health - Wikipedia

    The country implemented a clean air policy to reduce the road transport sector, which is responsible for 85% of particulate matter of less than 2.5 microns (PM2.5) total emissions and 72% of particulate matter of less than 10 microns (PM10) [38] Most successful policies were: Improving fuel quality by reducing the sulfur content in diesel

  8. Particulates - Wikipedia

    en.wikipedia.org/wiki/Particulates

    The largest US study on acute health effects of coarse particle pollution between 2.5 and 10 micrometers in diameter was published 2008 and found an association with hospital admissions for cardiovascular diseases but no evidence of an association with the number of hospital admissions for respiratory diseases. [229]

  9. Health effect - Wikipedia

    en.wikipedia.org/wiki/Health_effect

    Health effects are an important consideration in many areas, such as hygiene, pollution studies, occupational safety and health, ([nutrition]) and health sciences in general. Some of the major environmental sources of health effects are air pollution, water pollution, soil contamination, noise pollution and over-illumination. [citation needed]
