PM stands for particulate matter on the order of microns. PM is also often referred to as aerosols. While the chemical composition of particulate matter is important, its size is the dominant factor when it comes to human health considerat...
· Smart Air Recommended Top 3 Air Quality Monitors. Elitech Temtop LKC-1000S+: Sensor provides real-time measurements of PM and PM 10 mass concentrations, formaldehyde and volatile organic compounds (VOCs). It also displays temperature, relative humidity and AQI. It features a histogram function to display PM concentration changes in the latest 12 hours.
· Monitor the real-time level via websites and mobile phone applications. is only one of several factors influencing the air quality. Minimise the amount of time you spend outdoors. Wearing a face mask (rated at N95 or higher) will help but these masks only provide limited effectiveness against ultrafine If you work outdoors ...
· PM is a potentially dangerous category of air pollutants, and it is important to understand what it is, where it comes from and how to deal with it. By monitoring outdoor air quality and taking a few simple steps in your home, you can limit your exposure to PM
PM means the mass per cubic metre of air of particles with a size (diameter) generally less than micrometres (µm). PM is also known as fine particulate matter ( micrometres is one 400 th of a millimetre). Health Effects of PM: Inhalation of particulate pollution can have adverse health impacts, and there is understood to be no ...
Suspended particles in the air are also known as dusts, which can cause air pollution if they are high in content, and they contain substances that can affect human particles can generally be divided into total suspended particulate matter (TSP), inhalable particulate matter (PM10) and fine dust particulate matter ().Here are the differences and relationships between the three ...
· For instance, China uses its own AQI scale and India uses a scale it calls National Air Quality Index (NAQI). Both of these are more “forgiving” scales. For example, A concentration of 45 micrograms would be an AQI of 124 in the US but just 75 in India. Even the definition of the number is different. For example, an AQI of 151 is ...
· The one-hour concentration readings are only an indicative measure of the current air quality. There are four bands on the concentration scale: 0 to 55 for normal, 56 to 150 for ...
· The UK is required to meet National Air Quality objectives and EU directive pollution limits. The limit for average levels of tiny particulate matter () in air in the UK is 25 µg/m3.
· An Air Quality Index or AQI is an overall scheme that transforms values of individual pollutants such as , PM10, SO2, CO etc. into a single number or set of numbers that can then be used to communicate the current levels of air quality and their corresponding health impact consistently across the entire country. The Indian AQI system classifies pollution levels into Good(0-50) to Severe ...
· Particulate Matter (PM) is a mixture of solid and liquid particles that are suspended in the air. These are categorized into coarse, fine and ultrafine. Coarse particles have a diameter of micrometres to 10 micrometres (about 25 to 100 times thinner than a human hair), are relatively heavier and thus tend to settle. Dust, spores and pollen are some examples. refers to particles that ...

· Air quality standard for PM in outdoor air. PM and PM 10 affect every country in the world. Hence, each country has set its limits for particulates in the air. The following table (courtesy Wikipedia) will make matters clear. Country: PM 10 : PM : Yearly average: Daily average: Yearly average: Daily average : Australia: None: 50 microns/m3: 8 microns/m3: 25 microns/m3: China: 70 ...
· For this reason, the US Environmental Protection Agency (EPA) sets standards for PM10 and concentrations in urban air, and provides data so that the public can check the air quality index. The EPA regulates primary particulate emissions and precursors to secondary emissions (NOx, sulfur,and ammonia). Many areas in the US and Europe still frequently violate the particulate …
PM stands for particulate matter (also called particle pollution): the term for a mixture of solid particles and liquid droplets found in the air. Some particles, such as dust, dirt, soot, or smoke, are large or dark enough to be seen with the naked eye. Others are so small they …
· Many regions with the most air pollution don't even measure air pollution, like the Middle East. They also found that the weakest air quality standards are often violated, particularly in ...
