PM2.5 is only one of several factors influencing the air quality. Minimise the amount of time Download Table | AQI and air pollution levels with corresponding PM 2.5 concentrations (Ministry of Environmental Protection of the People's Republic of The difference is that WAQA shows the health effects of PM2.5 at lower levels than the AQI does. In other words, WAQA shows that air quality is unhealthy earlier PM2.5 refers to atmospheric particulate matter (PM) that have a diameter of less The table below will give you a sense of what levels of PM2.5 are harmful and The higher the AQI value, the greater the level of air pollution, which means the greater the health concerns. AQI Look-up Table for PM2.5 concentrations 3 Dec 2019 In both years, high levels of PM2.5 concentrations were observed in northern and central China, especially in the BTH and surrounding regions av M Gustafsson · 2014 · Citerat av 20 — About 70% of the population was exposed to PM2. 5 annual mean concentrations lower than 10 µg/m3, while less than 15% experienced levels above 12 µg/m3. exposure to ambient air pollution is still an important issue and the concentration levels, especially of nitrogen dioxide (NO2) and particles (PM10 and PM2.5), Read the air pollution in Sweden, get real-time, historical and forecast PM2.5 and weather data with AirVisual.

Note that PM10 includes PM2.5. Potential health effects from exposure to particulate matter: The break points of different pollutants for example (0-30) is Good for PM2.5, (31-60) is Satisfactory have been defined based on the effect of of these pollutants on health. These breakpoints are then mapped to the corresponding AQI ranges of (0-50) for Good and (51-100) for Satisfactory. What is PM 2.5?

However, the WHO set a guideline limit which reflects the level at which increased mortality from exposure to PM 2.5 is likely. This recommended guideline limit is an annual mean concentration of 10 micrograms per cubic metre of air (µg m-3)3. In the European Union (EU), the legal annual mean air quality limit value (the “legal limit”) for PM 2.5
