Check out the real-time air pollution map, for more than 80 countries. Can not find your city on the map? The GAIA air quality monitor uses laser particle sensors to measure in real-time PM2.5 and PM10 particle pollution, which is one of the most harmful air pollutants.

2023年7月11日 · Smaller particles, such as PM2.5, pose a greater risk as they can penetrate deep into the respiratory system and even enter the bloodstream, causing a range of adverse health effects. PM levels are typically measured in micrograms per cubic meter (µg/m3) of air.

2024年9月30日 · The concentration of PM 2.5 indoors, where people spend about 90 percent of their time, can sometimes surpass outdoor levels, especially in poorly ventilated spaces. Cooking without proper ventilation or smoking indoors can rapidly increase PM 2.5 concentrations, negatively impacting the indoor air quality.

“Ozone and PM” refers to data for Ozone plus PM2.5 plus PM10. Each hour, the highest among these 3 pollutants is displayed for each monitor and each contour. Click on a monitor to reveal …

2024年6月20日 · Some particles less than 10 micrometers in diameter can get deep into your lungs and some may even get into your bloodstream. Of these, particles less than 2.5 micrometers in diameter, also known as fine particles or PM 2.5, pose the greatest risk to health.

2024年12月19日 · EPA is setting the level of the primary (health-based) annual PM 2.5 standard at 9.0 micrograms per cubic meter to provide increased public health protection, consistent with the available health science.

The Indoor Air Hygiene Institute requires a PM2.5 level of 12 μg/m 3 or less, with infrequent or no spikes of 35 μg/m 3 or higher. The most common way to manage PM2.5 in indoor air is using HEPA-grade filters in the air management system and/or air purifiers.

2024年8月16日 · Using a nationwide network of monitoring sites, EPA has developed ambient air quality trends for particle pollution, also called Particulate Matter (PM). PM 2.5 describes fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller. Under the Clean Air Act, EPA sets and reviews national air quality standards for PM.
