Concernant les PM2.5, il n’existe aujourd’hui aucune réglementation bien qu’elles soient plus petites et donc plus dangereuses pour la santé que les PM10. L’union européenne a fixé son objectif de qualité à 20μg/m3 en moyenne sur l’année. L’OMS recommande, quant à elle, une valeur de 10 μg/m3.
In this paper, hourly observations of precipitation, wind, and PM2.5 and PM10 concentrations in Qinhuangdao from 2016 to 2018 were used to study the effects of precipitation and wind on PM2.5 and PM10 concentrations. The results show that precipitation has a certain wet scavenging effect on PM2.5 and PM10, and the scavenging effect on PM10 is greater than that on PM2.5.
Alternatively, PM 2.5 is more associated with fuel burning, industrial combustion processes and vehicle emissions. 0.1 m 1 m 10 m Anthropogenic: • Sulfates • Nitrates • Ammonia • Carbon • Lead • Organics Fine Coarse Natural: • Soil • Dust • Seasalt • Bioaerosols 2.5 m Sizes and Composition of Particulate Matter 4 Ultra-Fine Aerosol Aerodynamic Diameter (1 m = 1 x 10-6 m) ance Coarse PMs range between 2.5 – 10 μm, also called PM 10. Fine PMs range 2.5 μm or below, also called PM 2.5. Btw, those who don’t know, ‘μm’ stands for a micrometer or, 1×10^-6 m. Just a simpler conversion: 1 mm = 1000 μm.

Utsläppen av PM2,5 har minskat med en tredjedel i Sverige sedan år 1990, men har endast minskat svagt sedan millennieskiftet. Koncentrationen av PM2,5 har minskat sedan år 2000 och endast i södra Sverige överskrids miljömålets årsmedelvärde, 10 µg/m3.

Indexeringen PM10 används för att representera partiklar mindre än 10 mikrometer, och PM2.5 representerar partiklar mindre än 2.5 mikrometers aerodynamisk moreover, there is good evidence of the effects of exposure to various particle size ranges1: pm10 pm2.5 pm1 particles 10 μm in diameter or The size distribution between 10 and 368 nm was measured continuously by using a differential mobility particle sizer (DMPS) system.
For PM2.5, short-term exposures (up to 24-hours duration) have been associated with premature mortality, increased hospital admissions for heart or lung causes, acute and chronic bronchitis, asthma attacks, emergency room visits, respiratory symptoms, and restricted activity days.
As a result, even though levels of both PM 2.5 and PM 10 are under constant surveillance, experts believe that PM 2.5 is the more harmful of the two. PM stands for Particulate Matter. PM2.5 and PM10 are minute particles present in the air and exposure to it is very harmful for health. When the level of these particles increases and penetrate Additionally, PM 2.5 (fine) contains PM 1.0 (ultrafine) as well. To put things into perspective, human hair has a diameter of 50-70 µm and a grain of sand has a diameter of 90 µm.

Particulate matter (PM) is a term used to describe the mixture of solid particles and liquid droplets in the air. It can be either human-made or naturally occurring.
