What Severine asked in her mail was: I don't understand why pm2.5 concentrations are often higher than pm10 concentrations. Aren't PM smaller than 2.5 micro included in PM smaller than 10 micro? 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.

Que a diferencia de otro tipo de contaminantes, como el ozono, las partículas PM 2.5 son ultra finas y fácilmente  29 Nov 2019 Las partículas de la materia en suspensión (PM10 y PM2.5) son los productos contaminantes de mayor impacto medioambiental. Cuanto más  Particulate matter such as PM10, PM2.5, PM1 and PM0.1 is defined as the fraction of particles with an aerodynamic diameter smaller than respectively 10, 2.5,  El medidor de particulas indica también la temperatura y humedad del aire.

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.

Halterna av partiklar (PM2,5) kontrolleras i ett antal svenska tätorter med avancerade mätinstrument som kan leverera timmedelvärden. Sådana data kallas för realtidsdata.

The reason for upgrading from PM 10 to PM 2.5, explained by Dr Sarath Guttikunda in this explantion about PM 10 vs PM2.5 is that there are now new studies presenting evidence that PM 2.5 is more harmful than PM 10.As Dr Dr Sarath Guttikunda sates in the article, “physically, this makes sense since smaller than particle have a higher probability to go deeper into the lungs and harm people”.

In the European Union (EU), the legal annual mean air quality limit value (the “legal limit 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.

Here’s how the two contrast.

Research shows that every 10ug/m3 increase in PM 2.5, increases all-cause mortality between 3-26%, chances of childhood asthma by 16%, chances of lung cancer by 36% and heart attacks by 44%. 2016-02-04 Temtop M10 air quality monitor detects PM2.5 particles, HCHO, TVOC, and AQI on various occasions and displays real-time data to give you a safe and healthy environment. Features: Easy to get an overview of the readings of PM2.5, HCHO, TVOC and AQI Run up to 4-6 hours on one single charge, suitable to use at home, office, car and outdoor. ABSTRACTThis study investigates the effects of sea-land breezes (SLBs) and northeastern monsoon (NEM) on the physicochemical properties of particulate matter (PM) in the atmosphere over southeastern coastal region of Taiwan Strait. The intensive PM sampling protocol was consecutively conducted for forty-eight hours.
