PM 2.5 is also known as fine particulate matter (2.5 micrometres is one 400 th of a millimetre). Health Effects of PM: Inhalation of particulate pollution can have adverse health impacts, and there

12 Nov 2020 "Under 'zero-firecracker' scenario, the level of PM2.5 is likely to be the lowest in the past four years as not so calm surface winds in Delhi will 

But few of us really know what they are talking about, mainly because it is just one characteristic of a complex category. The level of PM2.5 should be considered seriously. Studies showed that an increase in PM concentration leads to direct mortality of the population (3) . Another study (4) done in European countries pointed out that exposure to PM pollution causes a decrease in lifespan by 8.6 months. These breakpoints are then mapped to the corresponding AQI ranges of (0-50) for Good and (51-100) for Satisfactory. So a PM2.5(ug/m3) level of 31 will be represented by PM2.5 AQI of 51 which corresponds to Satisfactory. It is important to note whether PM2.5 or PM10 data on online websites is represented as AQI or ug/m3.

As of 2018 so far, the top 10 most polluted cities in the world might surprise you. Delhi has been bashed in the news frequently for its shocking air quality, but comes in at number 14, with Beijing hot on its heels at number 16. PM2.5 and Global Policy. As research continues to surface about the consequences of high PM2.5 levels, more countries have started to take notice. Because PM2.5 is airborne, it has quickly spread beyond cities and has begun to influence human health on a global scale. The GAIA air quality monitoring stations are using high-tech laser particle sensors to measure in real-time PM2.5 pollution, which is one of the most harmful air pollutants.

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

Scientific paper  late matter (PM10, PM2.5), as well as meteorological parameters, such as air sensors tend to be less precise in correctly measuring the pollutant level, and  Recent articles about the improved PM2.5 levels in 2015 have not mentioned weather factors.

Primary sources of PM2.5 emission are vehicle exhaust, incomplete combustion of wood or farm byproducts, forest fire, cooking, and dust. The secondary sources are the chemical reactions of gases like sulfur dioxide, nitrogen oxide, and nitrogen oxides, etc.

Research from the CARB-initiated Children’s Health Study found that children living in communities with high levels of PM2.5 had slower lung growth, and had smaller lungs at age 18 compared to children who lived in communities with low PM2.5 levels. India’s PM2.5 levels worst in world in 2019. According to the report, India was followed by Nepal, Niger, Qatar and Nigeria in exposure to PM 2.5, which are fine, Start wearing a N95 face mask when walking in Bangkok, the air pollutant PM2.5 is at unhealthy levels.
